Note on the growth of endemic soft-muzzled trout Salmothymus obtusirostris translocated into a Dalmatian river

The growth in standard length of endemic soft-muzzled trout Salmothymus obtusirostris, translocated to the Zrnovnica river about 25 years ago, was studied. Before the Prancevica dam was built at the other side of the karst mountain where the river springs from, the river Zrnovnica existed only temporarily and therefore did not provide a habitat for fish. The S. obtusirostris specimens caught ranged from 15.5 to 33.5 cm in standard length and from 80 to 425 g in weight. The growth in standard length of this population could be expressed by the following von Bertalanffy expression: L-t = 48.68(1-e(-0.2379(t-0.1261))). These results indicate that S. obtusirostris adapted to the new environment. They also show translocation to be a useful tool for its conservation. Nevertheless, the protection of this endangered species should be of the utmost importance.
