TASA DE PRODUCCIÓN DE HUEVOS DE COPÉPODOS DEL PACÍFICO CENTRAL MEXICANO
Abstract
Se estimó la producción de huevos en aguas mexicanas del Pacífico tropical oriental mediante indicadores en copépodos pelágicos bajo condiciones de laboratorio. Los copépodos fueron recolectados durante abril de 2015, separados e incubados en tres estaciones oceanográficas frente a las costas de Guerrero, México. Solo Labidocera acutifrons, Subeucalanus pileatus y Centropages furcatus presentaron actividad reproductora. Los indicadores de producción secundaria fueron la tasa de producción de huevos (TPH), la relación masa-longitud y el factor de condición. La especie con mayor TPH y el valor más alto de factor de condición (K) fue L. acutifrons. En las tres especies se observó un crecimiento de tipo alométrico. Esta es la primera estimación de producción secundaria de zooplancton en el Pacífico Central de México, por lo que debe ampliarse a un mayor número de taxa y a una escala temporal-espacial estacional mayor.
Copepod egg production rate in pelagic copepods in the Mexican Central Pacific
Estimates of secondary production through indicators from pelagic copepods under laboratory conditions were carried out in Mexican waters of the eastern tropical Pacific. Copepods were collected during April 2015, separated and in three oceanographic stations off the coast of Guerrero, Mexico. Only Labidocera acutifrons, Subeucalanus pileatus and Centropages furcatus presented reproductive activity. Secondary production indicators were the rate of egg production (TPH), the mass-length relationship and condition factor. The species with the highest TPH and the highest value of condition factor (K) was Labidocera acutifrons. In all three species allometric growth was observed. This is the first estimate of secondary production for zooplankton in the Mexican Central Pacific. Thus it should be extended to a larger number of taxa and for a wider seasonal space-time scale
