In the catch composition of organisms by size predominated the median with an average weight of 172.2 g. to 43.1 % followed by small with an average weight of 104.3 g. to 29.3 % and to a lesser extent the large size with an average of 326 g. At 27.6 % Total catch volumes registered reached the corvinillas 793.66 pounds . Both the volume of fishing , such as catch per unit effort (cpue) was higher in Leonidas Plaza ( p value > 0,05 ). A socio – economic study was conducted, and found that of those surveyed fishermen only 70 % havea level of primary education and only 30 % attended high.
