The aim of the present study was to determine various types of hemocytes, total and differential hemocyte count and to show some indices of phagocytosis, including percent phagocytosis and phagocytic index in Indian white shrimp, Fenneropenaeus indicus in Iranian shrimp farms. The hemolymph was extracted from the shrimps and mixed with anticoagulant. It then stained and Yeast was added as forei...

It is estimated that approximately 60% of disease losses in shrimp aquaculture have been caused by viral pathogens and 20% by bacterial pathogens. By comparison, losses to fungi and parasites have been relatively small. For bacterial pathogens, Vibrio species are the most important while for viral pathogens importance has changed since 2003 when domesticated and genetically selected stocks of t...

Population parameters were estimated for goatfish (Upeneus sulphureus, Cuvier, 1829) as a small size and abundant species in the Persian Gulf ecosystem. A method of Tropfish R package based on length frequencies analysis was used. A total of 520 fish samples were taken monthly from landing stations in the coastal area of Iranian Waters in the Persian Gulf (Bushehr coasts) from January 2017 to D...

Monthly length frequency data of banana shrimp, Penaeus merguiensis were collected from the coastal waters of North east Persian Gulf, from January 2012 to January 2013. Software package FiSAT was used to analyze the length frequency data. Growth parameters, mortalities, exploitation rate and recruitment pattern were estimated from the carapace length in the area. Based on length – weight relat...
