during the period from late metamorphic larvae to early juveniles by a 20-day rearing
experiment under different salinity regimes (1, 4, 8, 16 and 32 ppt). Effects of low-salinity on
growth and development were examined and the changes in the prolactin (PRL) production
level in the pituitary and the gill chloride cell morphology were examined as physiological
backgrounds for low salinity adaptation. PRL cells and chloride cells were identified by …
