Length-weight relationships of European eel Anguilla Anguilla(Linnaeus, 1758) from six karst catchments of the Adriatic basin, Croatia

This study presents the first references available for the length–weight re- lationships (LWRs) of eels from six karstic rivers in Croatia. A total of 380 European eels 13.0–76.0 cm long were collected by electro-fishing from six karst catchments of the Adriatic basin between 2004 and 2007. Eels of 34.0 cm in length dominated (over 50%) the catches, while abundance of eel smaller than 15.0 cm was very low. Value b of LWRs remained within the range between 2.5957 and 2.8155 , which indicates a negative allometric growth. CPUE (g 100 m -1) rapidly declined during the period of sampling, probably due to environmental changes, but also due to global disappearance of this species.
