ABSTRACT Purpose: To describe the epidemiological and clinical profile of hospitalized patients with retinoblastoma in Brazil. Methods: Using data from the Hospital Cancer Registry of the Instituto Nacional de Câncer, patients with the morphological codes of retinoblastoma who were diagnosed between 2000 to 2018, aged 0–19 years, and followed up in registered hospitals (analytical cases) were selected. The relative and absolute frequencies of demographic, clinical, diagnostic, therapeutic, and outcome variables were described. Hospital performance indicators were calculated and compared between hospitals qualified and not qualified to treat pediatric oncology cases and between hospitals with different case volumes (<20, 20-75, >75 cases). Results: Of the 2,269 identified analytical cases from 86 institutions, 48% were from the Southeast, 54% were male, and 66% were aged <4 years. The proportion of missing data (NA) was too high for several variables. Approximately 84% of the patients were from the public health system, 40% had a positive family history, and 88% had unilateral involvement. The first treatment included surgery in 58.3% of the patients (NA=2), Approximately 36.6% of these patients achieved complete remission, 10.8% achieved partial remission, and 12.7% died (NA=59%). Hospital performance indicators were within the target in >90% of the patients. The median time between the first appointment and diagnosis (6 days, interquartile range [IQR] 1–14) was significantly lower and the median time to death was longer (343 days, IQR, 212-539) in high-volume hospitals (>75 cases) than in medium- and low-volume hospitals. Conclusions: Despite the high proportion of missing data, we found that the delay in diagnosis is due to prehospital factors. Additionally, there is a need for educational programs for healthcare professionals and families that emphasize early identification and referral to specialized centers. Future studies should focus on the impact of Hospital Cancer Registry data completeness on outcomes, causes of delay in diagnosis, regional inequalities, and barriers to accessing specialized services.

What motivates voters to support candidates with backgrounds in public security for Brazil’s National Congress, the so-called Law & Order (L&O) politicians? The 2018 elections witnessed a surge in parliamentarians from police and military backgrounds and the election of a president closely aligned with this agenda. We explore whether this trend correlates with municipal-level violence indicators and the presence of municipal capacity in the security sector, employing various regression models that account for socioeconomic, demographic, political, and geographic factors. Our findings from the additive model reveal a negative association between the level of violence and votes for L&O candidates. This suggests a potential disconnection between fear, victimization, and support for repressive policies, while also indicating that local capacity in the security sector tend to enhance L&O candidates’ performance. However, our model incorporating the interaction between both variables uncovers that violence exacerbates the negative impact on L&O voting when the city has capacity in the security sector. This may reflect a municipal-level preference for preventive measures, particularly in more violent areas, which contrasts with the generally repressive stance of L&O candidates.

ABSTRACT Soil water balance models can be a good option for studying crop growth and yield responses under different water supply levels. The aim of this study was to evaluate the effect of different irrigation strategies on sunflower yield and water productivity using field experiments and soil water balance simulations. Two field experiments were performed. In 2018/19, four irrigation strategies (aimed at maintaining soil available water at 80, 70, 60, and 50% of total available water) were evaluated. In 2020/21 an irrigated and a rain-fed treatment were evaluated. The SIMDualKc model was calibrated and validated to simulate soil water balance and derive the dual coefficients using plant variables from field observations. Grain yield was highest in the treatment maintained at 70% of total available water in Study I, suggesting that a water replenishment reduction strategy may be an alternative to irrigation management, especially in locations where water is scarce. The statistical indicators showed good performance of the model in simulating the water available in the soil, with the coefficient of determination > 0.90 and modeling efficiency above 0.86 for all cases. The study allowed the calibration of the single and basal crop coefficients of sunflower, which are important parameters for irrigation management. levels simulations performed 201819 2018 19 2018/19 aimed 80 70 60 50 evaluated 202021 2020 21 2020/2 rainfed rain fed observations I management scarce 090 0 90 0.9 086 86 0.8 cases 20181 201 1 2018/1 8 7 6 5 20202 202 2 2020/ 09 9 0. 08 20 2018/

RESUMO Os modelos de balanço hídrico do solo podem ser uma boa opção para estudar o crescimento das culturas e as respostas de rendimento sob diferentes níveis de fornecimento de água. O objetivo deste estudo foi avaliar os efeitos de diferentes estratégias de irrigação na produtividade do girassol e na produtividade da água usando experimentos de campo e simulações de balanço hídrico do solo. Dois experimentos de campo foram realizados. Em 2018/19, foram utilizadas quatro estratégias de irrigação (mantida a água disponível no solo em 80, 70, 60 e 50% da água total disponível). Em 2020/21 foi utilizado um tratamento irrigado e de sequeiro. O modelo SIMDualKc foi calibrado e validado para simular o balanço hídrico do solo e derivar os coeficientes duais usando variáveis da planta a partir de observações de campo. A produtividade de grãos foi maior no tratamento mantido a 70% do total de água disponível no Estudo I, sugerindo que a redução da reposição de água pode ser uma alternativa para o manejo da irrigação, principalmente em locais onde a água é escassa. Os indicadores estatísticos mostraram um bom desempenho do modelo na simulação da água disponível no solo, com coeficiente de determinação > 0,90 e eficiência de modelagem acima de 0,86 para todos os casos. O estudo permitiu a calibração do coeficiente de cultura simples e basal do girassol, que são parâmetros importantes para o manejo da irrigação. realizados 201819 2018 19 2018/19 mantida 80 70 6 50 disponível. . disponível) 202021 2020 21 2020/2 sequeiro I escassa 090 0 90 0,9 086 86 0,8 casos 20181 201 1 2018/1 8 7 5 20202 202 2 2020/ 09 9 0, 08 20 2018/

Abstract The way residents occupy and operate houses influences the energy consumption. The objective of this paper is to findpatterns of occupant behaviour in actual data for thermal performance simulation.Data on occupancy of rooms and operation of doors and windows were obtained through a database created by means of application of questionnaires in low-income houses located in Florianópolis, southern Brazil. The reference profiles were obtained using cluster analysis, hierarchical and non-hierarchical techniques combined. Such profiles were submitted to computer simulations. The results showed significant variability within the clusters regarding the occupancy and operation of doors and windows. It was possible to verify the impact that different profiles have on the performance of the house, either due to occupancy or heat losses and gains from air changes through doors and windows. The combination of these effects resulted in some profiles that were highly vulnerable to external temperature conditions, while others were able to maintain the internal temperatures more constant. It was possible to verify that the use of reference profiles based on actual data lead to more reliable performance indicators. consumption simulationData simulation Data lowincome low income Florianópolis Brazil analysis nonhierarchical non combined simulations house conditions constant indicators

Resumo A forma como os moradores ocupam e operam as casas influencia o consumo de energia. O objetivo deste trabalho é encontrar padrões de comportamento dos moradores em dados reais para fins de simulação do desempenho térmico. Dados sobre ocupação de cômodos e funcionamento de portas e janelas foram obtidos por meio de um banco de dados criado por meio da aplicação de questionários em habitações de interesse social localizadas em Florianópolis. Os perfis de referência foram obtidos por meio de análise de agrupamento, com técnicas hierárquicas e não hierárquicas combinadas. Tais perfis foram submetidos a simulações computacionais. Os resultados mostraram variabilidade significativa entre os grupos quanto à ocupação e operação de portas e janelas. Foi possível verificar o impacto que diferentes perfis têm no desempenho da casa, seja pela ocupação ou pelas perdas de calor e ganhos com as trocas de ar através de portas e janelas. A combinação desses efeitos resultou em alguns perfis altamente vulneráveis às condições de temperatura externa, enquanto outros foram capazes de manter as temperaturas internas mais constantes. Foi possível verificar que a utilização de perfis de referência baseados em dados reais leva a indicadores de desempenho mais confiáveis. energia térmico Florianópolis agrupamento combinadas computacionais casa externa constantes confiáveis

Abstract The study analyzed the technical and environmental feasibility of using Erythrina poeppigiana to produce plywood with different adhesives: phenol-formaldehyde (PF), urea-formaldehyde (UF), and castor oil-based polyurethane (PUA). The physical and mechanical properties of the plywood were evaluated, including apparent density, moisture content, water absorption, thickness swelling, shear resistance, and static bending. Tests proved erythrina’s suitability for non-structural plywood production. The environmental impact of the production process was also evaluated, using embedded energy and CO2e emissions as indicators. The results showed that plywood produced with PU adhesive had better environmental performance compared to panels with FF and UF adhesives. T1 treatment (PF) had the highest embodied energy, while T2 (UF) had the highest CO2e emission. Overall, the study suggests that using erythrina to produce plywood can be a viable option for promoting regional socioeconomic development while also being environmentally sustainable and presents an advantage over foreign plywood in terms of environmental performance. adhesives phenolformaldehyde phenol formaldehyde PF, PF , ureaformaldehyde urea UF, oilbased oil based PUA.

Abstract Ceramic coating finds are widely used in buildings due to their durability, weather resistance and attractive aesthetics. Over time, these facades are subject to various factors that can cause anomalies, affecting their appearance and performance. Different degrees of protection and exposure to degradation agents, as well as the variability in the quality of materials and construction processes lead to different degradation along the facade. The objective of the research is to study the variability of degradation along the facade, how it appears and which are the main factors responsible. The research is based on a database, developed from inspections of buildings in Brasília, using the Degradation Measurement Method (MMD. The analyzes are based on degradation indicators. The results show that there is variability in degradation resulting from numerous variables. Older buildings have greater extents of degradation. It is observed that there is variability in degradation between the floors of the building's facade, mainly in relation to the sixth floor and top, showing that the position on the facade is a significant factor in the degradation process. The identification of causes of degradation and the most vulnerable points of the facade allows the development of appropriate design and maintenance strategies. durability aesthetics time anomalies performance agents responsible database Brasília MMD.

RESUMEN Paraguay ha aumentado la inversión en educación en la última década por medio del Fondo Nacional de Inversión Pública y Desarrollo (FONACIDE) cuya finalidad consiste en abordar las carencias que afectan a la educación paraguaya. Entonces, considerando la creciente preocupación por la gestión de los recursos públicos dada la escasa infraestructura y el deficiente servicio del almuerzo escolar, en este trabajo se pretende analizar la eficiencia de la gestión de los gastos públicos en educación del FONACIDE de los departamentos de Paraguay durante el período 2015 a 2017, a través de la aplicación de la técnica Data Envelopment Analysis (DEA) con análisis de ventana y retornos variables de escala con orientación producto. La técnica DEA con análisis de ventana consiste en medir el nivel de eficiencia de varias Decision Making Units (DMUs) en diferentes períodos de tiempo basado en el principio de promedios móviles. Los resultados muestran que la ineficiencia técnica pura media nacional es del 11,04%, por tanto, los departamentos en general podrían mejorar sus indicadores educativos utilizando los mismos niveles de financiamiento. Además, el mayor acceso a recursos no está vinculado a mejores rendimientos educativos. Por tanto, para potenciar el rendimiento educativo es necesario establecer otros criterios de redistribución presupuestaria del FONACIDE, considerando la necesidad de infraestructura y número de alumnos matriculados por departamento.

ABSTRACT Paraguay has increased investment in education over the past decade through the National Fund for Public Investment and Development (FONACIDE), whose goal is to address the deficiencies affecting Paraguayan education. Considering the growing concern over the management of public resources given the inadequate infrastructure and poor school lunch service, this paper aims to analyze the efficiency of public spending management in education by FONACIDE in the departments of Paraguay during the period 2015 to 2017. This is achieved through the application of the Data Envelopment Analysis (DEA) technique with window analysis and variable returns to scale with product orientation. The DEA technique with window analysis measures the efficiency level of several Decision-Making Units (DMUs) over different periods based on the moving averages principle. The results show that the average national pure technical inefficiency is 11.04%, meaning that the departments, in general, could improve their educational indicators using the same funding levels. Additionally, greater access to resources is not linked to better educational outcomes. Therefore, to enhance educational performance, it is necessary to establish other budget redistribution criteria for FONACIDE, considering the need for infrastructure and the number of enrolled students per department

Summary: The cocoa crop is very susceptible to nutritional deficiencies and moniliasis caused by the phytopathogen Moniliophthora roreri. One of the alternatives to synthetic chemicals are compounds based on silicon (Si). In the present investigation, the ef fect of silicon as a biostimulant in cocoa cultivation and as a biological control agent for M. roreri was evaluated. In the experiment, five Si treatments were used: T1 (4.00 kg ha-1), T2 (3.00 kg ha-1), T3 (2.00 kg ha-1) and T4 (1.5 kg ha-1) and a control treatment (without application). Production indicators, ear number, fresh and dry weight of almonds, dry weight of 100 almonds and crop yield were determined. In addition, the incidence and severity of the disease at 60, 120 and 180 days af ter the application of Si and the ef ficiency of the treatments. The significantly higher results for the variables: Production, ear number, fresh and dry weight of almond and dry weight of 100 almonds, were obtained by applying 4 kg ha-1 of Si, all doses of Si exceeded the control (P ≤ 0.05) in the variables related to production. In the control of the phytopathogen (M. roreri), the dose of 4 kg ha-1 Si decreased the incidence and severity of the disease by more than 50%. The application of Si can be an option in cocoa cultivation as a biostimulant and biological control agent for M. roreri.

Resumen: El cultivo del cacao es muy susceptible a deficiencias nutrimentales y a la moniliasis ocasionada por el fitopatógeno Moniliophthora roreri. Una de las alternativas a los productos químicos sintéticos son los compuestos a base de silicio (Si). En la presente investigación se evaluó el efecto del silicio como bioestimulante en el cultivo de cacao y agente de control biológico de M. roreri. En el experimento se utilizaron cincos tratamientos de Si: T1 (4.00 kg ha-1), T2 (3.00 kg ha-1), T3 (2.00 kg ha-1) y T4 (1.5 kg ha-1) y un tratamiento control (sin aplicación). Se determinaron los indicadores de producción, número de mazorca, peso fresco y seco de almendras, peso seco de 100 almendras y el rendimiento del cultivo. Además, de la incidencia y severidad de la enfermedad a los 60, 120 y 180 días después de la aplicación del Si y la eficiencia de los tratamientos. Los resultados significativamente superiores para las variables: Producción, número mazorca, peso fresco y seco de almendra y peso seco de 100 almendra, se obtuvieron mediante la aplicación de 4 kg ha-1 de Si, todas las dosis de Si superaron al control (P ≤ 0.05) en las variables relacionas a la producción. En el control del fitopatógeno (M. roreri), la dosis de 4 kg ha-1 Si disminuyó la incidencia y la severidad de la enfermedad en más del 50%. La aplicación de Si puede ser una opción en el cultivo de cacao como bioestimulante y agente de control biológico de M. roreri.

ABSTRACT The contribution of plant residues throughout the sugarcane cycles favors the increase of organic matter and the activity of microorganisms in the soil, especially in the surface layers. Soil texture also has an important effect on ecological processes and soil quality. In this context, the objective of this study was to evaluate soil biological attributes in different sugarcane cultivation cycles under mechanized harvesting in an Oxisol in the Savanna region of Central Brazil. The study was conducted in commercial areas under sugarcane cultivation during the 2018/2019 season, which were considered homogeneous in terms of soil and climatic conditions, with the source of variation among the areas being the cultivation cycles (C1: one cultivation cycle; C3: three cultivation cycles; C7: seven cultivation cycles) and a savanna vegetation area selected as a reference. Microbiological variables were determined in two layers, 0-0.1 and 0.1-0.2 m. The variables related to microbial biomass and texture were subjected to principal component analysis. Areas with longer sugarcane cultivation cycles show higher proportion of microbial biomass carbon in the total organic carbon in subsurface layers (microbial quotient). The performance of the soil microbial community, as expressed by total organic carbon and microbial biomass nitrogen indicators, was associated with higher presence of clay and silt, i.e., soil particles smaller than 0.02 mm. quality context Brazil 20182019 2018 2019 2018/201 season conditions C1 C (C1 cycle C3 C7 reference 00.1 001 0 0.1 1 0-0. 0.10.2 0102 0.2 2 0.1-0. m analysis quotient. quotient . quotient) community indicators silt ie i e i.e. 002 02 0.0 mm 2018201 201 2018/20 (C 00 00. 01 0. 0-0 10 0.10. 010 0.1-0 i.e 201820 20 2018/2 0- 0.10 0.1- 20182 2018/

RESUMO O aporte de resíduos vegetais ao longo dos ciclos da cana-de-açúcar favorece o incremento de matéria orgânica e atividade de microrganismos no solo, especialmente nas camadas superficiais. A textura do solo também tem um efeito importante nos processos ecológicos e na qualidade do solo. Nesse sentido, o objetivo desta pesquisa foi avaliar atributos biológicos do solo em diferentes ciclos de cultivo de cana-de-açúcar sob colheita mecanizada, em um Latossolo da região de cerrado do Brasil Central. O estudo foi realizado em áreas comerciais de cultivo de cana-de-açúcar na safra 2018/2019, consideradas homogêneas em termos de condições edafoclimáticas, tendo como fonte de variação entre as áreas os ciclos de cultivo (C1: um ciclo de cultivo; C3: três ciclos de cultivo; C7: sete ciclos de cultivo) e uma área de vegetação de cerrado selecionada como referência. Foram determinadas variáveis microbiológicas nas camadas de 0-0,10 e 0,10-0,20 m. As variáveis relacionados à biomassa microbiana e textura foram submetidos à análise de componentes principais. Áreas com ciclos de cultivo de cana-de-açúcar mais longos apresentaram maior proporção de carbono da biomassa microbiana no carbono orgânico total nas camadas subterrâneas (quociente microbiano). O desempenho da comunidade microbiana do solo, expresso pelos indicadores carbono orgânico total e nitrogênio da biomassa microbiana foi associado à maior presença de argila e silte, ou seja, partículas de solo menores que 0,02 mm. canadeaçúcar cana açúcar superficiais sentido mecanizada Central 20182019 2018 2019 2018/2019 edafoclimáticas C1 C (C1 C3 C7 referência 00,10 0010 0 0,10 10 0-0,1 0,100,20 010020 0,20 20 0,10-0,2 m principais quociente microbiano. microbiano . microbiano) silte seja 002 02 0,0 mm 2018201 201 2018/201 (C 00 00,1 001 010 0,1 1 0-0, 100 0,100,2 01002 020 0,2 2 0,10-0, 0, 201820 2018/20 00, 01 0-0 0,100, 0100 0,10-0 20182 2018/2 0- 0,100 0,10- 2018/

Global databases such as Web of Science and Scopus have determined the standard indicators to measure the research output in national comparisons and its quality evaluation for decades. Already classic studies of science proved that this landscape of scientific production was distorted by using overly selective bibliographical indexes that were considered “international databases” while their coverage was severely limited. A relevant part of the bibliometric literature in the last 10 years has revolved around the limitations of these global data sources and the search for alternatives to explore more comprehensive universes of the scholarly output, considering all disciplines and languages. Particularly relevant in this debate are some recently created bibliographic services and search engines that provide new opportunities: Dimensions, Lens, Open Alex, CrossRef and Google Scholar. Our specific contribution to these studies relies on a methodological shift based on a convergence between prosopography and bibliometrics. For that end, we selected two countries that can be considered “peripheral centers” in the Latin American region. Firstly, we determined a universe of national researchers of the National Council for Scientific and Technological Development (CNPq, Brazil) and the National Council for Scientific and Technical Research (CONICET, Argentina). The target populations are composed of 10,619 tenured researchers at CONICET and 14,418 holders of the CNPq’s “research productivity fellowship”. Secondly, we built a database with their comprehensive publishing performance uploaded in the national curricular information systems, the Brazilian Lattes and Argentina’s SIGEVA, that includes metadata for all articles. After computational and manual data cleaning of this database, we retained a total 464,361 articles for Brazil and 81,005 for Argentina published in 2013-2020. The comparative study shows that Argentina and Brazil have similar patterns of coverage in the global databases, although they differ in terms of collaboration practices and national publishing.

ABSTRACT Using data from the 2020 higher education admission process, this article analyzes the distributive behavior of the special quotas of a Chilean socio-educational inclusion policy. Several indicators have been created to profile both the demand and the programmatic offer that adheres to this initiative. The results show that the allocation of special quotas is neither homogeneous nor random; the higher the elitism, academic profile and socioeconomic characteristics of a program's enrollment, the lower its number of vacancies for special admission. Likewise, special quotas increase in programs with low levels of demand and that concentrate students with low performance in admission tests. The conclusions discuss whether the contribution of the most prestigious programs make to social inclusion is more symbolic than real, as well as the configuration of a logic of instrumental use of special admission in programs with low demand.

RESUMEN Utilizando datos del proceso de admisión a la educación superior en 2020, este artículo analiza el comportamiento distributivo de los cupos especiales de una política de inclusión socioeducativa chilena. Se crearon distintos indicadores para perfilar tanto la demanda como la oferta programática que adhiere a esta iniciativa. Los resultados evidencian que la asignación de cupos especiales no es homogénea ni azarosa; conforme mayor es la elitización, perfil académico y atributos socioeconómicos de la matrícula de un programa, menor es su cantidad de vacantes para admisión especial. Asimismo, los cupos especiales aumentan en carreras con bajos niveles de demanda y que concentran estudiantes con bajo desempeño en pruebas de admisión. Las conclusiones discuten si la contribución que los programas de mayor prestigio hacen a la inclusión social es más simbólica que real, así como la configuración de una lógica de uso instrumental de la admisión especial en programas de baja demanda.

ABSTRACT This paper describes the main socio-political events that took place in Uruguay in 2023, Luis Lacalle Pou’s fourth year as president (supported by a rightist coalition). During the 2019 electoral campaign, many of Lacalle Pou’s promises were not based on a programmatic shift but on better management (non-policy politics), particularly of economic and security policies. While macroeconomic indicators show moderate performance, security indicators have not improved substantially. Dormant during the pandemic, security became a very important issue in 2023, materialized in high homicide rates and violence linked to drug trafficking and gang conflict. Much like in other Latin American countries, security has become a protracted problem that no single administration can improve. Furthermore, in 2023 there were a series of politi- cal scandals, some of which were linked to organized crime and drug-trafficking. We posit that, jointly, these facts undermine the better management capacity rhetoric. This suggests that the current administration lost the advantage of non-policy poli- tics, which could affect its electoral chances in 2024.

RESUMEN Este artículo describe los principales acontecimientos socio-políticos durante 2023 en Uru- guay, el cuarto año de gobierno de Luis Lacalle Pou (un presidente apoyado por una coali- ción de derecha). Durante la campaña electoral de 2019, muchas de las promesas de Lacalle Pou se basaron en la garantía de una mejor gestión (non-policy politics), en particular en materia de política económica y de seguridad. Si bien los indicadores macroeconómicos muestran un desempeño moderado, los indicadores de seguridad no han mejorado sustancialmente. Los problemas de seguridad, en estado latente durante la pandemia, volvieron a ser un asunto importante en 2023 como muestran las altas tasas de homicidios y violen- cia vinculada al narcotráfico y al conflicto entre bandas. Al igual que en otros países de América Latina, la seguridad se ha convertido en un problema persistente de no sencilla resolución en un único período de gobierno. Además, en 2023 salieron a la luz una serie de escándalos políticos, algunos de ellos vinculados con el crimen organizado y el narcotráfico. En este artículo argumentamos que estos hechos, considerados en conjunto, socavaron las apelaciones discursivas a la mejor capacidad de gestión. Esto sugiere que la actual ad- ministración perdió la ventaja del non-policy politics, lo que podría afectar sus chances electorales en 2024.

RESUMEN Introducción: Los hoteles son instalaciones cuyo recurso fundamental constituye su capital humano, requieren sistemáticamente de inversiones sobre el conocimiento, el continuo perfeccionamiento de los hábitos de trabajo y conductas laborales seguras que permitan el mejoramiento del desempeño individual y colectivo, y con ello, la calidad de los servicios.

ABSTRACT Introduction: Hotels, whose fundamental resource constitutes their human capital, systematically require investments in knowledge, the continuous improvement of work habits and safe work behaviors that allow the improvement of individual and collective performance, and with it, the quality of services. At the “Meliá Cayo Santa María Complex” the performance of staff is evaluated using general indicators, without considering specific functions and tasks, which does not allow individual performance to be managed based on organizational performance. Objective: Propose a procedure for evaluating the performance of staff that contributes to the management of occupational health and safety at the “Meliá Cayo Santa María Complex.” Methods: Empirical methods were used: documentary analysis of the work plans of the staff, procedure manuals, strategic planning of the hotel, performance evaluations and position qualifiers, interviews with managers and direct observation of the process performance evaluation. Results: As the main contribution of the research, a procedure was developed for evaluating the performance of staff that allows improving health and safety management in the hotel complex. Conclusions: The proposal for evaluating the performance of staff based on the competencies and associated strategic behaviors as a contribution to the commitment to safety and health, the improvement of the quality of the worker's work life and effective managerial performance.

Abstract Continuous illumination and increased feeding periods have enhanced growth in commercial fish species. However, oxygen consumption under these conditions has yet to be previously assessed in agastric short-intestine fish. This study evaluated Chirostoma estor (Atherinopsidae) oxygen consumption under three specific feeding and light regimes: resting-unfed, routine-fed, and continuous light/feeding. Fish in the continuous light/feeding condition presented oxygen consumption levels 60 and 20% higher than resting-unfed and routine-fed fish, respectively. The latter implies that constant high oxygen supply levels are required to satisfy the demand for C. estor raised under these high growth rate conditions. The present study shows the relevance of determining oxygen consumption levels during continuous illumination and extended feeding periods to consider optimal oxygen levels required to achieve better performance indicators, such as the growth and welfare of atherinopsids and species with similar digestive configurations.

Resumen La iluminación continua y el aumento de frecuencias alimenticias han mejorado el crecimiento de peces en cultivo. Sin embargo, el consumo de oxígeno en estas condiciones no se ha evaluado en peces agástricos de intestino corto. Este estudio evaluó el consumo de oxígeno de Chirostoma estor bajo tres regímenes específicos de alimentación y luz: reposo sin alimentación, alimentación de rutina y alimentación/luz continua. En este último tratamiento los peces presentaron niveles de consumo de oxígeno de 60 y 20% más altos que los peces en reposo y con alimentación rutinaria, respectivamente. Esto implica que se requieren niveles elevados y constantes de suministro de oxígeno para satisfacer la demanda de C. estor en cultivo en condiciones crecimiento acelerado. El presente estudio muestra la relevancia de determinar los niveles de consumo de oxígeno bajo protocolos de crecimiento acelerado para lograr mejores indicadores de desempeño de otras especies con configuraciones digestivas similares.
