Estudio comparativo del zooplancton (biomasa y composición) en dos bahías del Mar Caribe Mexicano

Abstract

Existen diferencias notables en biomasa, composición y distribución del zooplancton, entre las bahías de la Ascensión y de Chetumal, en el· litoral oriental de la Península de Yucatán. La de Chetumal representa un sistema heterogéneo desde el punto de vista hidrológico y la comunidad zooplánctica local está representada básicamente por especies eurihalinas; las larvas de peces y decápodos son un componente importante del zooplancton local; esto indica que esta bahía es propicia para la crianza de estas especies. Sin embargo, es probable que la mayor parte de las larvas sean exportadas o bien, emigren del sistema a partir de sUs etapas juveniles o autónomas. El aislamiento de la influencia marina y la baja energía interna restringen la productividad y riqueza faunística de la Bahía de Chetumal. La Bahía de la Ascensión es un sistema hidrológicamente más homogéneo, con mayor influencia marina; su fauna zooplánctica local es más diversa y abundante, yes probable que la emigración de larvas de peces y de decápodos sea menos intensa que en el caso de la Bahía de Chetumal.

Strong differences were observed in zooplankton biomass, composítion and distribution in Chetumal and Ascension bays, eastern coast of the Yucatan Península, Mexico. Chetumal Bay is an hydrologically heterogeneous system and the local zooplanktic cornmunity is represented mainly by eurihaline elements. Fish and decapod larvae are relevant eonstituents of the local zooplankton, suggesting a significant breeding area. However, mos! of these larvae migrate passively or actively when reaching juvenile, autonomous stages. The isolation from (he influence of marine water and the internal low energy restríet both productivity and faunistic diversity in Chetumal. Ascensión Bay is, hydrologically, a more homogeneous system, with higher marine input. Its local zooplanktic fauna is more diverse and abundant. Probably, the passive migration of fish and decapod larvae is lower than in Chetumal
