  abstract = {{T}he effects of salinity on the expression of genes coding for growth hormone ({GH}) and prolactin-1 ({PRL}1) were studied in various natural populations of the black-chinned tilapia {S}arotherodon melanotheron from {W}est {A}frica. {I}ndividuals were sampled in {J}une 2005 in six locations in {S}enegal and the {G}ambia, at various salinities between 0 and 101. {T}he poorest condition factors were recorded in the most saline sampling site and the best growth in the fish from a marine environment. {T}he pituitary {GH} m{RNA} levels were significantly higher in fish adapted to seawater, whereas the {PRL}1 m{RNA} levels were highest in fish adapted to fresh- and brackish water. {T}hese results show that the {PRL}1 m{RNA} levels seem to reflect relatively well the differences in environmental salinity, in contrast to those of {GH}, which would tend instead to reflect the individual growth in each environment. {H}owever, no relation could be found between growth in the hypersaline areas and the expression profile of {GH}. {A}lthough the fish analysed were morphologically identical, the expression of genes coding for {GH} and {PRL}1 showed large differences between individuals. {T}his inter-individual variation in gene expression remains poorly understood.},
