ANALYSIS OF THE FISH ACCOMPANYING OF SHRIMP (FAS) CAUGHT WITH CHURUPA NET IN THE LAGOON SYSTEM TOPOLOBAMPO, SINALOA, MEXICO

From September to December 2013 we carry out an analysis of fish accompanying of shrimp in the lagoon system Topolobampo, captured with the net of fishing churupa assisted by three vessels, a richness of 14 species was recorded. They were identified taxonomically highlighting the orders Clupeiformes, Scorpaeniformes, Perciformes, Pleuronectiformes and Tetradontiformes containing families like Engraulidae, Scorpaenidae, Serranidae, Gerreidae, Haemulidae, Sciaenidae, Chaetodontidae, Achiridae, Cynoglossidae, Balistidae, and Tetraodontidae. The species mostly captured by the three ships are Diapterus peruvianus, Sphoeroides annulatus, Balistes polylepis, Anchovia macrolepidota and Etropus crossotus. Biometric parameters (length, height, and weight average) of harvested species showed no significant differences. A. mazatlanus(black sole) had the lowest average weight (1.70 g), while the sardine (A. macrolepidota) obtained the highest record with 38.57 g. Most fishing importance lies in the gray sole (E. crossotus), the crappie yellowfin (D. peruvianus) and sardine (A. macrolepidota) both for its high biomass and spatio-temporal distribution. In catch per unit effort, crappie yellowfin (D. peruvianus), the cochi (Balistes polylepis), gray sole, puffer fish (S. annulatus) and sardines obtained values from 1.058 to 1.525 organisms per hour. Sizes and weights stand very low, so it is urgent regulation of fishing gear, selecting a suitable mesh light, allowing catches are commercial and productive from an economic, social and environmental vision
