Crecimiento y producción de carpa común (Cyprinus carpio Linnaeus, 1758) durante la época de sequía y lluvias en un bordo del Estado de México, México

Abstract

This paper describes the relationship between the environmental parameters (physical, chemical, absolute abundance of zooplankton and zoobenthos), and the absolute weight growth (CAP) of the carp (Cyprinus carpio), in a temporary pond of the State of México, Morelos, during the dry and wet season. The behavior of the system in both periods was influence by depth. During the dry season the water alkalinity, hardness, temperature and oxygen concentration increased, while transparency decreased. This season also registered the highest zooplankton and zoobenthos abundances, in this period, the most import parameter were, hardness and orthophosphate concentration, and in the wet season, hardness and pH. In the wet season, the environmental paramenters did not have values as drastic as those registered during the dry season, allowing the fishes to grow more. The yield in the wet season was 1,367% higher than during the dry season. During the dry season, the CAP was more related to the conductivity, pH and turbidity parameters, while in the dry season it was more related to the zoobenthos abundance and pH. The wet period is the stocking season recommended because is the most appropiate growth fish season.
