First record of palmetto bass (Morone saxatilis x M. chrysops) in the Croatian part of the river Danube

Abstract

On October 19, 2010, a male specimen of palmetto bass (Morone saxatilis x M. chrysops) was caught by commercial fishing net in the Croatian section of the river Danube (302 mm TL and 331 g). It was in its third year of age (2+). A condition factor of 1.20 was based on the total length. Six specimens of prey fish were found in its gut (22.97 g altogether). Morphometric and meristic traits of this palmetto bass are presented and its possible threat to the fish community is discussed.
