  abstract = {{T}hrough the experiments presented here we wanted to test whether egg production of the black-chinned tilapia {S}arotherodon melanotheron heudelotii under experimental conditions varies as a function of ambient salinity (fresh waters vs. sea waters vs. hypersaline waters, 0, 35 and 70, respectively) and whether these responses differ between fish acclimated within a few weeks from fresh water to saline and hypersaline environments (experiments {E}1 and {E}2, monitoring over 10 and 18 weeks), and individuals born and raised all life long at the experimental salinities ({E}3, monitoring over 18 weeks). {I}n total, 233 spawns were collected. {I}n each of the three experiments, the reproductive investment (gram of egg per gram of female over 2 weeks) did not differ between salinities of 0 and 35, whereas it was 2-3 times lower at 70 than at 0-35, because of lower spawning frequency ({E}1-{E}3), smaller clutch size ({E}1) and lower spawn mass ({E}1-{E}3). {F}inally, fish acclimated to salinity from fresh water over a few weeks and those maintained at a particular salinity all life long showed similar reproductive traits, thereby emphasizing the remarkable physiological plasticity of this species.},
