Abstract

The Persian Gulf is Unique in the world of open waters due to high fish species diversity. Every year in shrimp catch season about 9975 Kg bycatch and non-target species are caught with shrimp trawl which included teleost fishes less than LM50 or Chondroepiphysis fishes that have high ecological value. These fishes are not market species and used in other industries such as fish meal, inevitably. This review tries to investigate current researches on machine vision ability to sort fishes by species. While trapped fishes in shrimp trawl sorted immediately, non-target species could be returned to sea and can be hoped that a high percentage of them survive and return to the cycle of the ecosystem.
