AbstractThe age of first sexual maturation is an important reproductive trait for genetic selection or to fix some experimental design in research programs. The detection of precocious puberty is essential to plan cohort management in aquaculture. So far no early individual indicator exists without killing the fish. We propose to identify non-lethal/non invasive markers in trout and sea bass that could accurately predict the maturational status of individual fish several months before any visible sign of maturation could be detected such as sperm production or ovulation. Based on our previous data, "a priori" candidate markers were blood concentrations of reproductive hormones
