Ichthyoplakton surveys were conducted in December (rainy season), 1993 and February (dry season), 1994, during the RV Victor Hensen German-Costa Rican Expedition to the Gulf of Nicoya and Golfo Dulce. Costa Rica. Samples from the inner, central, and outer areas of each gulf were collected in oblique tows with a bongo net of 0.6 m mouth diameter, 2.5 m long and 1000-μm mesh. A total of 416 fish larvae of 22 families; were sorted out of 14 samples. Stations of both the maximum (II) and the minimum (I) family richness were located in Golfo Dulce. Mean total larval abundances were 124.9 and 197.2 individuals 10 m-2 for the Gulf of Nicoya and Golfo Dulce, respectively, while mean larval densities ranged from 95.3 larvae 10 m-2 in December to 236.7 larvae 10 m-2 in February. However, no statistical differences between gulfs or seasons were detected. due to the high within-group variability. Cluster Analysis, Multi-Dimensional Scaling (MDS), and non-parametric tests showed two well-defined major groups: (I) the Gulf of Nicoya neritic assemblage, represented by Engraulids, Sciaenids, and Gobiids (inner and central stations), and (2) the oceanic assemblage, dominated by Myctophids, Bregmacerotids, Ophiidids, and Trichiurids (outer stations off the Gulf of Nicoya and Golfo Dulce). A third, although less defined group, was an Ophichthid-dominated assemblage (typical in areas nearby coral or rocky reefs). These assemblages closely resemble the clusters based upon adult fish data of the beamtrawl catches of the same cruise. This publication is the first to report on the ichthyoplankton community of Golfo Dulce. |

Se realizaron arrastres oblicuos en estaciones en las zonas interna, central y externa de cada golfo, con una red de 0,6 m de diámetro de boca, 2.5 m de largo y 1000-μm de poro. En 14 muestras se extrajo un total de 416 larvas de 22 familias de peces. Tanto la estación con máxima riqueza de familias (II) como la mínima (I) están localizadas en Golfo Dulce. En el Golfo de Nicoya la densidad promedio fue de 124.9 larvas 10 m-2, mientras que en Golfo Dulce fue de 197.2 larvas 10 m-2. En diciembre se encontró un promedio de 95.3 larvas 10 m-2 y en febrero fueron 236.7 larvas 10 m-2. Sin embargo, no se registraron diferencias estadísticamente significativas de las abundancias totales entre golfos o entre épocas, debido a la alta variabilidad dentro de los grupos. Mediante Análisis de Conglomerados y de Escala Multidimensional, se establecieron dos tipos de comunidades ictioplanctónicas definidas: (I) el Grupo Nerítico del Golfo de Nicoya, representado por las familias Engraulidae, Sciaenidae y Gobiidae (estaciones internas y centrales), y (2) el Grupo Oceanico, dominado por Myctophidae, Bregmacerotidae, Ophiididae y Trichiuridae (fuera de la boca de ambos golfos). Un tercer grupo, mas disperso, estaba constituido por estaciones dominadas por larvas leptocefalas de la familia Ophichthidae. y fue típico en zonas aledanas a los arrecifes coralinos o rocosos. Esta clasificación se asemeja a la descrita para la comunidades de peces adultos recolectados durante el mismo crucero con una red de arrastre.
