Abstract

Taken as a whole, Leiognathus splendens spawns throughout the year along
the Porto Novo coast with two peaks, during October-December|January and
during April-May. Individual fish appears to spawn twice a year for a short
duration. High gonado-somatic indices correspond well with the peak spawning
months, and females always have higher values. The Relative condition factor
does not indicate any relation with the reproductive cycle. Females mature between
76 mm and 111 mm total length whereas males mature, between 81 mm
and 111 mm. Sex ratio shows general preponderance of males and chi-square
test indicates significant difference between years. Fecundity, varying between
7099 and 21,507, appears to increase with length of fish.
