Mouth Size and Body Length Relations for Freshwater Fish Species

Özet

We estimated the relationships between total vertical, horizontal and mouth area with total length for seven fish speciescaught from Lake Volvi (Northern Greece) during September 2016-February 2017. All relationships were significantlyallometric (P<0.05) and were described by the power regressionwith r2 values ranging from 0.435 to 0.882. The establishmentof such relationships is important for defining the ecological position of species in the food web, as well as for fisherymanagement purposes.
