The black-chinned tilapia (Sarotherodon melanotheron) is a paternal mouthbrooder. Pairs of adult black-chinned tilapia were raised in freshwater and the males were sampled during the mouthbrooding cycle. Sampling also occurred 10 days after release of the free-swimming fry for comparison. During the first week of incubation of the eggs, total androgens and estradiol were low (<5 and <0.3 ng/ml, respectively). During the second week of brooding, when the eggs have hatched and they are called… CONTINUE READING
