PRODUCTION OF PACIFIC RED SNAPPER (Lutjanus peru) IN FLOATING CAGES

Abstract

The Pacific red snapper (Lutjanus peru) is a scale species that is highly valued in the state of Guerrero, Mexico, for which fishermen have opted to use aquiculture to offer a quality product during the seasons of greatest demand. There has not been permanent technical monitoring for the breeding implemented, which has generated low yields and economic losses. Therefore, since the year 2008, the National Fishery Institute (Instituto Nacional de Pesca, INAPESCA), together with the Costa Grande-Guerrero cooperative, began projects directed at fattening the Pacific red snapper in a locality with the aim of evaluating the growth of this species in floating cages through indicators of growth and economic profitability. Under breeding, with designed feeding, the Pacific red snapper reached the growth desired in length and weight, obtaining a commercial “dish” size in four months, and reducing production costs. The growth of L. peru was isometric with an instant growth rate qualified as fast, the amount of food supplied (FCA) showed good yield for a source of natural origin. The earnings obtained were higher than the point of equilibrium, indicating profitability of the fish.
