Resumo A seletividade é uma característica das artes de pesca capazes de capturar peixes de determinado tamanho e espécie da distribuição populacional existente. O tamanho da malha é um dos fatores importantes que influenciam a seletividade da rede de emalhar. Devido ao tamanho diferente, eles pegam vários tipos de peixes. Este trabalho centra-se na seletividade de dois tamanhos de malha de emalhar (8,89 e 10,16 cm) na captura de cavala e na construção de uma rede de emalhar nas águas de Sungailiat. O método de pesca experimental e a análise de seletividade foram usados para a preparação mais seletiva das artes de pesca, se o valor da maior razão de pesca para o comprimento do garfo (L) for alto e o valor do desvio padrão (S) for mais próximo de 1. Conclui-se que para ser mais seletivo dev ter um maior valor S (L) de 0,999267194 no comprimento do garfo (L = 54,95 cm), um maior valor S (L) 0,997096071 e com (L = 66,55 cm) para o tamanho da malha 8,89 cm e 10,16 cm respectivamente.

Abstract Selectivity is a fishing gear characteristic capable of catching fish of a specific size and species from the existing population distribution. Mesh size is one of the important factors that influence gillnets’ selectivity, because different length-classes of fish are caught by them. This report focuses on the selectivity of two mesh sizes of gillnets (8.89 cm and 10.16 cm) on mackerel's catch and constructing a gillnet in Sungailiat waters. Experimental fishing methods and selectivity analysis were used for the fishing gear’s more selective preparation, if the largest fishing ratio's value at the fork length (L) is high and the standard deviation value (S) is closer to 1. It is concluded that to be more selective a largest S (L) value of 0.999267194 at fork length (L=54.95 cm), and with a larger value of S (L) 0.997096071 and with (L=66.55 cm) for mesh Sizes 8.89 cm and 10.16 cm, respectively.

Although several animal models for human cerebral malaria have been proposed in the past, name have shown pathological findings that are similar to those seen in humans. In order to develop an animal model for human cerebral malaria, we studied the pathology of brains of Plasmodium coatneyi (primate malaria parasite)-infected rhesus monkeys. Our study demonstrated parazitized erythrocyte (PRBC) sequestration and cytoadherence of knobs on PRBC to endothelial cells in cerebral microvessels of these monkeys. This similar to the findings een in human cerebral malaria. Crebral microvessels with sequestred PRBC were shown by immunohistochemistry to possess CD36, TSP and ICAM-1. These proteins were not evident in cerebral microvessels of uninfected control monkeys. Our study indicates, for the first time, that rhesus monkeys infected with P. coatneyi can be used as a primate model to study human cerebral malaria.
