AB  - Artisanal gillnet fishery was investigated in Ayam&eacute; I reservoir during a survey of 12 months. Mean value of Catch Per Unit Effort (CPUE) was 9.23&plusmn;5.18 kg of fish per trip. Both commercially important tilapiine species, <I>Sarotherodon melanotheron </I>and <I>Oreochromis niloticus, </I>constituted &gt;57% of gillnet catches. The von Bertanlanffy growth parameters (L<SUB>&infin;</SUB> and K) computed from length-frequency data through the FiSAT software were (L<SUB>&infin;</SUB> = 35.3 cm and K = 0.4 year<SUP>-1</SUP>) for<I> O. niloticus</I> and (L&infin; = 33 cm and K = 0.55 year<SUP>-1</SUP>) for <I>S. melanotheron</I>. Resources status analysis by comparison of fishing mortality rates F with the target [(F<SUB>opt</SUB>) and limit (F<SUB>limit</SUB>)] ones, biological reference points indicated that <I>S. melanotheron </I>is overfished whereas, <I>O. niloticus</I> is exploited close to the optimum level. These results allowed us to suggest some management strategies for sustainable exploitation of the studied tilapiine stocks in the reservoir.
