摘要
Length-weight relationships for Leucos aula, Scardinius hesperidicus, and Squalius squalus from the Piediluco Lake were provided. Data were collected by means of electrofishing, gill-nets (mesh sizes varying from 5 to 55mm) and fyke-nets (mesh size 16mm, total length 8m, mouth width 1.5m). The monitoring campaigns were carried out seasonally in the years 2004 and 2011, and in autumn 2012. A total of 5,198 specimens were analyzed. For all the species the value of b ranged between 3.163 for Leucos aula and 3.297 for S. hesperidicus. For L. aula a new maximum total length was also reported.
