| Resumo: |
In the Ebrie lagoon, the reproductive season of T. jentinki jentinki ranges from August to Februarywith a main spawning period in November, which is related to the rising of lagoon water level. The size of both males and females at first sexual maturity is about 160 mm fork-length. Each female of T. jentinki jentinki lays between 110 and 420 eggs depending on the size. It represents an average of about 1,100 eggs/kg weight. The female keeps the eggs in its mouth: this oral incubation reaches an average of 15 days at the end of which the released fry measures from 12 to 20 mm fork length. The species growth in length has been studied by examination of scales structures (circuli and annuli). This growth, compared to other cichlids is relatively slow. Molluscs constitute most of the diet. In the Ebrie lagoon, the artisanal fishery yearly catch is about 300 MT of T. jentinki jentinki , which could be suitable for pisciculture production.
