Abstract copyright bass Cichla temensis is an important species at the Amazon basin, since commercial, subsistence and recreational fisheries simultaneously exploit it.Cichla temensis is the preferred species by recreational fishers and it has been strongly exploited, mainly at the Negro river, the second largest tributary of the COENZYME Q10 200 MG Amazon River.It was used data from experimental fisheries, collected at the middle stretch of Stove Knobs Negro river, which were coupled with previously published data on its population dynamics, to run a yield per recruit model and build scenarios of sustainable fisheries.The results showed that the age of the first catch is a key variable to successful management of the copyright bass stocks at this region.
