Abstract

Freshwater A. scabra is an endemic species of the Bia river precisely in Aboisso and Biaka. A total of 720 individuals were collected from August 2014 to July 2015 in the above-mentioned localities. No significant difference of the sex ratio have been observed (Aboisso: 1.2 M/F; Biaka: 1.16 M/F). The initial volume of eggs has increased during incubation of 66.25 and 79.17% of stage I to III respectively in Aboisso and Biaka. Thus, the size (Lt) at first maturity obtained respectively in males and females was estimated at 8.28 and 8.21 cm at Aboisso and 8.13 cm and 8.01 cm at Biaka.

It was a respectively variation of 0.15 cm and 0.20 cm in males and females of both study sites. Aboisso absolute fecundity ranged from 7876 eggs (2.5 cm Lc and 6.4 cm Lt) to 33156 egg (4.1 cm Lc and 11.7 cm Lt) while at Biaka, it fluctuated between 6941 eggs (2.3 cm Lc and 6.7 cm Lt) to 37721 eggs (4.3 cm Lc et 12.4 cm Lt).The relative fecundity (FR) was 704
