Length–girth relationships for freshwater fishes from Lake Volvi (Northern Greece)
Author(s): Kyritsi S, Mantzouni I and Moutopoulos DK
Abstract: We estimated the relationships between total length (TL) and opercular (G
ope) and maximum (G
max) girths, for the seven most important freshwater fish species in Lake Volvi during 2016-2017. Both G
ope and G
max increased significant linearly with TL for all studied species with all r
2 values being greater than 0.83. When G
ope and G
max were plotted against TL for all species combined, four general length–girth relationships were identified, the slopes of which differed significantly (ANCOVA,
P< 0.05) and corresponded to three general body shapes. Twenty-nine out of 52 species-season combinations showed that the intercept a and/or slope b values differed significantly among seasons, with more than half of which are attributed to the effect of spring and summer. The implications of girth measurements for selectivity estimates are also discussed.
