Se identificaron estadios larvales de 19 especies pertenecientes a 18 familias, en su mayor¨ªa de inter¨¦s para la pesca. Las familias m¨¢s abundantes fueron Photichthyidae (179 larvas¡¤1000 m-3) y Hemiramphidae (106 larvas¡¤1000 m-3). Se determin¨® la distribuci¨®n y abundancia de huevos mediante el an¨¢lisis gr¨¢fico de mapas de dispersi¨®n espacial. Destacaron por su frecuencia de ocurrencia y abundancia las larvas de Vinciguerria lucetia (Familia Photichthydae) con 112 larvas¡¤1000 m-3, Cetengraulis mysticetus (Familia Engraulidae) con 104 larvas¡¤1000 m-3, y Hyporhamphus sp. y Oxyporhamphus sp. (Familia Hemiramphidae) con 73 y 33 larvas¡¤1000 m-3 respectivamente. Considerando las limitaciones del muestreo (hora, tipo de red y arrastre), es muy probable que los valores de abundancia de larvas fueron subestimados We show the results of taxonomic and ecological analyses carried out on ichthyoplankton caught in 23 surface tows during the PACIFICO XXXVIII-ERFEN XXXVI oceanographic research campaign in the Colombian Pacific Ocean. Larvae of 19 fish species belonging to 18 families were identified. Most of the fish larvae were commercial value species. The most abundant family was Photichthyidae (179 larvae¡¤1000 m-3), followed by Hemiramphidae with 106 larvae¡¤1000 m-3. The spatial distribution and abundance of fish larvae and eggs were determined using dispersion maps (graphic analysis). Fish larvae abundances were probably underestimated due to sampling limitations (hour, type of net, and surface towing). However, larval abundances of Vinciguerria lucetia (Family Photichthydae: 112 larvae¡¤1000 m-3), Cetengraulis mysticetus (Family Engraulidae: 104 larvae¡¤1000 m-3), Hyporhamphus sp. (Family Hemiramphidae: 73 larvae¡¤1000 m-3), and Oxyporhamphus sp. (Family Hemiramphidae: 33 larvae¡¤1000 m-3) were outstanding %K ictioplancton %K huevos de peces %K larvas de peces %K Colombia %K Oc¨¦ano Pac¨ªfico %K Ichthyoplankton %K fish eggs %K fish larvae %K Colombia %K Pacific Ocean %U http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-71782006000200016
