Resumo O presente estudo foi realizado para descobrir novas descobertas sobre os valores máximos de comprimento e peso de Umbrina cirrosa na Baía de Saros (Mar Egeu do Norte, Turquia). Em 11 de setembro de 2016, um único espécime de Umbrina cirrosa com 68.8 cm de comprimento total e 2600.00 g de peso total foi capturado por linha de mão a uma profundidade de 20 m. O tamanho provável é o segundo maior comprimento já registrado em todos os mares do mundo.

Abstract The present study has been conducted to find out new findings on maximum length and weight values of Umbrina cirrosa in the Bay of Saros (Northern Aegean Sea, Turkey). On September, 11, 2016, a single specimen of Umbrina cirrosa with 68.8 cm total length and 2600.00 g total weight was caught by handline at a depth of 20 m. The provable size is the second largest length ever reported in the all seas of the world

Resumo Este estudo foi realizado em abril-junho de 2014 para determinar a fecundidade absoluta (F) da cavala (Scomber japonicus Houttuyn, 1782) na Baía de Saros (Mar Egeu, Turquia). As relações entre a fecundidade absoluta e comprimento total, peso total e a idade da cavala fêmeas foram estimados como F=0.0318TL4.81, F=1573.9 TW- 42858 e F=109607A-136129, respectivamente. Este estudo visa contribuir para a biologia reprodutiva de S. japonicus, apresentando as primeiras conclusões sobre a fecundidade absoluta das espécies para o Mar Egeu.

Abstract This study was carried out in April - June 2014 to determine absolute fecundity (F) of the chub mackerel (Scomber japonicus Houttuyn, 1782) in Saros Bay (Aegean Sea, Turkey). The relations between the absolute fecundity and total length, total weight and age of the chub mackerel females were estimated as F=0.0318TL4.81, F=1573.9TW- 42858 and F=109607A-136129, respectively. This study aims to contribute to the reproductive biology of S. japonicus by reporting the first findings about the absolute fecundity of the species for the Aegean Sea.

ABSTRACT The present study was conducted to investigate the influence of different levels of dietary phytogenic feed additive (PFA) on growth performance, caecal microbiota, and intestinal morphology of broilers. A total of 480 Ross-308 one-day-old male broilers chicks (body weight 43±3 g) were randomly assigned to 32 replicate pens of four experimental groups, each experimental group consisting of 8 replicates (each replicate pen consisting of 15 chicks). A basal diet was formulated based on corn and soybean meal that was fed to the control group. Other dietary treatments received a commercial PFA at 100 mg/kg (PFA100), 125 mg/kg (PFA125), and 150 mg/kg (PFA150). Body weight gain, feed intake, and feed conversion rate of broilers were recorded on 1-21, 22-42, and 1-42 days of age. One bird was slaughtered on the 21st and 42nd days and caecal contents were aseptically collected. Jejunal tissue samples were also collected on the same days. Total aerobic bacteria, coliforms, Escherichia coli, and lactobacilli were counted in the caecal contents. Villus height, villus diameter, crypt depth, muscular thickness, and goblet cell number per villus were recorded. There was no difference among the dietary treatments for growth performance and caecal microbe populations at any phase. However, the dietary PFA supplementation increased the villus height, villus width, muscularis thickness, and reduced the crypt depth and goblet cell number per villus in broilers compared to those fed control diets. In conclusion, this study suggests that dietary supplementation of a PFA consisting of blend of different spices and essential oils did not improve growth performance and caecal microbial populations despite a positive improvement in the jejunal morphometry of broilers.
