Short Communication Length-weight relationships of fishes from three northern Aegean estuarine systems (Greece)

Length–weight relationships for fish were originally used to provide information on the condition of fish and to determine whether somatic growth was isometric or allometric (Le Cren, 1951; Ricker, 1975). In fisheries biology, length–weight relationships are useful in determining weight and biomass when only length measurements are available, as indications of condition and to allow for comparisons of species growth between different regions. Length–weight relationships have been reported for Greek marine (Petrakis and Stergiou, 1995; Stergiou and Moutopoulos, 2001) and freshwater (Kleanthidis et al., 1999) species but data for estuarine fish are inadequate. In this study, the parameters of the length–weight relationships are reported for 43 freshwater, estuarine and marine fish species collected from three northern Aegean estuarine systems.
