Characterization of the Artisanal Fishery of Elasmobranchs in Puerto Casma, Ancash, Peru: 2010-2015

Abstract

The purpose of the research was to characterize the artisanal fishery of elasmobranchs from the Port of Casma, Ancash, Peru, 2010-2015. The population and sample was comprised by the fishing records of elasmobranchs landed and reported in the various geographical points of the jurisdiction of the Port of Casma. This information is comprised in the period 2010-2015. The values were processed through graphs, and then their behavior was analyzed, in addition to relating the total annual landings over time using the regression model. The most important landings were recorded in 2011 and 2015 with 2543 kg and 2305 kg respectively, presenting 4 target species being the "eagle ray", "guitar", "common dogfish", "hammerhead shark", the main vessel used for the artisanal fishery of elasmobranchs was the boat and the fishing gear used was the curtain. The main fishing ports that contributed to the landings in the Port of Casma were Islote La Viuda, Isla Blanca, El Buey, Hogadero, Cajero, Batan/Perez, and the regression model that described the total annual landings and time relationship was the polynomial regression model with an r2 of 0.158.
