Tortugas marinas durante el 2010 en Pisco, Perú

Abstract

Durante el 2010, se capturó 55 ejemplares de tortuga verde Chelonia mydas en La Aguada (13°51’S y 76°15’W) al sureste de la bahía de Paracas; el número promedio de tortugas capturadas por kilómetro de red tendida fue 3,08±2,5; el tamaño promedio de la LCC fue 60,3±10,5cm; el 78% de los ejemplares presentaron el patrón 5c, 4d, 4i y 11d, 11i, para los escudos centrales, costales y marginales, respectivamente. La TSM donde se capturaron varió entre 15,2 y 20,9 °C, la mayor ocurrencia de tortugas se registró de 18,5 a 20 °C. Los epibiontes más representativos fueron Platylepas hexastylos (56,8%), Conchoderma virgatum (26,9%) y Chelonibia testudinaria (13,3%); la ocurrencia de los ítems alimenticios: Clorophyta (78%), Rhodophyta (30%), Cnidaria (43%), Crustacea (43%), Polichaeta (17%), Mollusca (17%), arena (26%) y plástico (17%); el 72% de las tortugas presentaron cobertura algal, de las cuales el 65% fue el alga verde Enteromorpha sp.

ABSTRACT: During 2010, we captured 55 samples of green turtle Chelonia mydas in La Aguada (13°51’S and 76°15’W) to the southeast of Paracas Bay; the average number of turtle caught per kilometre of network lying was 3,08 ±2,5; the average size of the LCC was 60,3 ±10.5 cm; 78% of the specimens showed the pattern 5c, 4d, 4i and 11d, 11i for central shields, costal and marginal, respectively. The TSM where captured varied between 15.2 and 20.9 °C, the highest occurrence of turtles was recorded from 18.5 to 20 °C. The most representative epibionts were Platylepas hexastylos (56.8%), Conchoderma virgatum (26.9%) and Chelonibia testudinaria (13.3%); the occurrence of food items: Clorophyta (78%), Rhodophyta (30%), Cnidaria (43%), Crustacea (43%), Polichaeta (17%), Mollusca (17%), sand (26%) and plastic (17%); 72% of the turtles presented algal coverage, of which 65% was green algae Enteromorpha sp.
