3.5 Ichthyoplankton abundance
Larvae of fish found were mainly species of
Sardinella
in both seasons. In the peak season, a large number of
decapoda larvae
, primarily of the family Peneaidae and Portunidae were observed, as well as larvae of the species
Scyacium micrurum
. A higher abundance was observed during the peak season as compared to the lean season
(Figure 14). However these abundances were found to be not significant (Kruskal-Wallis H test, df = 1, P > 0.05).
