Abstract: Black gill syndrome is caused due to Fusarium Solano in shrimp. Associated diseases such as Vaybr Reeves, as well as Mitosis, the presence of heavy metals such as copper and cadmium can cause the incidence of the disease. The immune system is weakened by stress and the effect of these factors, so the disease happens. The disease symptoms are the Macroscopic and microscopic melanization of shrimp gills. The other pathological signs of the syndrome are hypertrophy and hyperplasia of gill and accumulation of hemisects in the gills. Due to nutritional importance of shrimps and also importance of shrimps in exports, the aim of this study was histopathological study of black gill disease in marine shrimps of coastal city of Bushehr, which is one of the most important areas. In this study, 100 pieces of shrimp were caught off shore in the coastal city of Bushehr. After fixing with the Davidson’s fixing solution, were transferred to Laboratory of Veterinary Medicine in Kazeroon Islamic Azad University and then Histopathological sections were prepared and carefully studied, and the results in the form of photographs and a table were reported. The results show that the risk of this syndrome is38% in the population of marine shrimps in coastal city of Bushehr. The histological results showed that there is necrosis, melanomas and hypertrophy in the gill cells. With regard to the above contents environmental conditions, special bacteria and fungi attack and nutritional deficiencies can weaken the immune system of shrimp, and this make a ground for the black Gill disease to appear.
