The green tiger shrimp (Penaeus semisulcatus) is an economically important species among native Iranian Shrimps. Microsatellite loci were developed for population genetic assessment of this species in Iranian waters. A total of eight polymorphic microsatellite loci were developed and tested on 40 individuals. The number of alleles per locus ranged from 5 to 12 with average of 7.38 per locus. Th...
Sea cucumber is an important component of the food chain in temperate ecosystems and coral reefs and plays an important role as a poultry eater and has antiviral, anti-cancer and anti-tumor properties in addition to oral administration and in the pharmaceutical industry. It has many uses. This creature swallows sediment on the bottom of aquaculture ponds and is in fact considered as a natural p...
This study aimed to investigate the quality of effluent water of a large shrimp farming complex in Chabahar region in Sistan and Baluchestan province (Iran). Fifteen sampling stations were designated in three distinct areas of these farms i.e. the water supply canal, the drainage canal and the receiving area of the farm effluents in Gwatar Gulf. Water samples were taken from June to December ...

intestinal coccidiosis, caused by eimeria species, is an economically-important disease of poultry production industry worldwide. this study was designed to investigate the prevalence of different eimeria species in the farmed broilers of khoy city, west azarbaijan, north west iran. a total of 26 broiler farms of different production capacities were arbitrarily selected and examined in 2013. in...
Biofloc systems were developed to improve environmental control over production. In places where water is scarce or land is expensive, more intensive forms of aquaculture must be practiced for cost-effective production. There are strong economic incentives for an aquaculture business to be more efficient with production inputs, especially the most costly (feed) and most limiting (water or land)...
