Abstract

GARCIA, Camilo B.. Ichthyoplankton seasonality in the Gulf of Salamanca, Colombian Caribbean Sea. Actu Biol [online]. 2019, vol.41, n.110, pp.21-40. ISSN 0304-3584.  http://dx.doi.org/10.17533/udea.acbi.v41n110a02.

The identity, density and spatial and temporal distribution of fish larvae and eggs were investigated in the Gulf of Salamanca, Colombian Caribbean. A total of 49 stations chosen randomly and distributed among the rainy and dry seasons were visited. Due to scarcity of previous studies taxonomic level was restricted to families. Twenty-six fish families were identified and two more could not be identified. Kruskal-Wallis one-way analysis of variance, non-metric multidimensional scaling and Bio-Env analysis were used to test hypotheses and search for patterns. Fish larvae and eggs have a patchy spatial distribution. Temporal distribution suggests a definite influence of seasonality on fish larvae assemblages with the transition time into the dry season (December) correlating to the highest abundance in numbers and biomass of fish larvae and eggs.

Keywords : Ichthyofauna; fish eggs; fish larvae; assemblages; Caribbean Sea; spatial-temporal distribution.
