Length-weight and length-length relationships for cavedano chub Squalius squalus (Bonaparte, 1837) in Italy

Abstract

Summary Data of 31496 specimens of cavedano chub Squalius squalus were collected in 89 different waterbodies distributed geographically throughout Italy and used to provide length–weight and length–length relationship for this species. The linear relationship between total length (TL) and standard length (SL) was described by the equation TL (cm) = 4.007 + 0.874 SL (cm). The resulting total length–weight equation for cavedano chub in Italy was: log10 W = −2.121 + 3.083 log10 TL (cm).
