Asociaciones de larvas de peces en una bahía del Caribe mexicano

Abstract

Se analizaron las variaciones interanuales del ictioplancton, en la Bahía de la Ascensión, Quintana Roo durante diciembre de 1994 a 1997. Fueron identificadas 32 familias, 35 géneros y 21 especies de peces. Las familias dominantes fueron la Gobiidae, Callionymidae, Clupeidae y Tetraodontidae. La diversidad larval fue baja comparada con la registrada en otras épocas del año (secas y lluvias). En diciembre de 1994 y 1995 se observaron tres asociaciones espaciales (interna, media y externa). En diciembre de 1996 y 1997 las asociaciones se conformaron por la mezcla de estaciones de la parte interna y externa de la bahía. Las familias dominantes caracterizaron a la mayoría de las asociaciones faunisticas. La densidad de huevos de peces fue más alta en la zona externa de la bahía, mientras que las larvas fueron más abundantes en la zona interna. Los principales factores que afectan a las asociaciones de larvas de peces durante diciembre (1994-1997) en la bahía de la Ascensión parecen estar relacionados a la localización de áreas de crianza, zonas de desove y al periodo y estrategia reproductiva de peces estuarinos y arrecifales.

Interannual ichthyoplankton variation, was analyzed in Bahía de la Ascensión, Mexico, during December of four consecutive years (1994-1997). A total of 32 families, 35 genera and 21 species of fish larvae were identified. The most abundant fish larvae were the Gobiidae followed by the Callionymidae, Clupeidae and Tetraodontidae. Larval diversity was low when compared with other periods (“dry” and “rainy”). Three spatial associations (internal, medium and external) were found in December 1994 and 1995. In 1996-1997, stations of the inner and outer parts of the bay were mixed. The dominant families characterized most of the faunal associations. Egg density was highest in the external zone of the bay, whereas larvae were most abundant in the inner area. Major factors affecting the fish larval assemblages during December (1994-1997) in Bahía de la Ascensión seem to be related to the nursery areas location and to the tropical fishes reproductive period.
