Abstract
Length–weight relations were estimated for 7 native fish species of the Louros River in north-western Greece, 6 of them being endemic to the Ionian Sea ecoregion. The b values ranged from 3.05 to 3.21. Five species, namely Cobitis hellenica Economidis et Nalbant, 1996; Pelasgus thesproticus (Stephanidis, 1939); Gasterosteus gymnurus Cuvier, 1829; Economidichthys pygmaeus (Holly, 1929); and Valencia letourneuxi (Sauvage, 1880) displayed an isometric growth pattern (b = 3) while the remaining two species—Salmo lourosensis Delling, 2011 and Telestes pleurobipunctatus (Stephanidis, 1939)—showed a positive allometric growth (b > 3). New maximum lengths are given for three species. Moreover, this study constitutes the first world report on the length–weight relations for 5 species and the first report for the Ionian Sea ecoregion for two other species.
