Length-weight relationships of three fish species from Trasimeno Lake, Italy

Abstract

Length-weight relationships for Alburnus arborella, Esox cisalpinus and Scardinius hesperidicus from Trasimeno Lake are provided. A total of 4,205 specimens were collected for examination from 2008 to 2014 throughout the lake by means of electrofishing and nets. For all species the value of b ranged from 2.887 for Esox cisalpinus males to 3.115 for Scardinius hesperidicus. The study provides the first reference of length-weight relationships for the three species. A new maximum total length is also reported for E.cisalpinus.
