Abstract

The results of the analysis of the ichthyoplankton obtained by means of superficial trawling in 23 sampling stations during the campaign Pacific XXXVIII ERFEN - XXXVI in the Colombian Pacific Ocean basin, are presented. The larval stages of 19 species belonging to 18 families were identified, most of them considered commercially valuable. The family Photichthyidae stands out for its abundance, followed by the family Hemiramphidae which showed the widest distribution. The egg distribution and abundance were determined by means of graphical analysis of spatial dispersion maps and the relationship between the fish larval distribution and abundance with the temperature, salinity, oxygen, chlorophyll a and nictimeral variation was evaluated. The physical-chemical variables behavior did not show anomalous changes, consequently it is considered as a normal period. The was no significant differences between the ichthyoplankton abundance during day and night (Mann Whitney, P = 0.2974), Nevertheless, the larval distribution and abundance in the coastal and oceanic zone was influenced by the chlorophyll, temperature and salinity. Considering the error for the simple conical net use and the type of trawling, it is suggested that the abundance is sub-estimated.
