Abstract
An ichthyoplankton survey was made at four stations along a longitudinal transect in the Pochote Estuary in Gulf of Nicoya, Costa Rica. Samples were taken monthly between June 1983 and March 1984. A yearly egg frequency curve was bimodal, showing peaks during May and August. A similar larval frecuency curve revealed three peaks: May, January-February and August. The peak abundance of both eggs and larvae was in May, possibly correlated to the transition period between wet and dry seasons. The less pronounced peaks occurred in both wet and dry periods with no apparent correlation to climate. Twenty larval types were identified to some taxonomic rank. Dominant types of larvae in this estuary, in order of importance, were: Gobiidae, CR-9 (an abundant, non-identified type), and Clupeiformes.
