摘要

As in higher vertebrates, vasotocin is also involved in osmoregulation in teleosts. However, the specific vasotocinergic influences and actions in the extremely complex osmoregulatory system of teleosts are only partially deciphered. In the present investigation we examined the effects of long-term acclimation to different salinities on the vasotocin system of Rivulus marmoratus, a teleost species inhabiting brackish waters of tropical mangrove forests. Caused by tidal influences, this species is naturally exposed to fast changes in salinity ranging from freshwater to seawater conditions without showing behavioral alterations. R. marmoratus was obtained from a breeding population continuously maintained (25℃, LD 12:12, 1.6% salinity) by DLGN. Due to the fact that this species changes sex, only males and hermaphrodites could be investigated.
