Abstract

Length-weight relationships (LWRs) were estimated for ten freshwater fish species such as a species of crucian carp, gin-buna, Carassius langsdorfii Temminck & Schlegel, 1846, lake minnow Phynchocypris percnura (Pallas, 1814), a species of  stone loach Barbatula toni (Dybowski, 1869), Japanese smelt Hypomesus nipponensis McAllister, 1963, masu salmon Oncorhynchus masou (Brevoort, 1856), rainbow trout O. mykiss (Walbaum, 1792), whitespotted char Salvelinus leucomaenis (Pallas, 1814), ninespine stickleback Pungitius pungitius (Linnaeus, 1758), a species of sculpin, hana-kajika, Cottus nozawae Synder, 1911, and a species of goby Rhinogobius sp. OR. Specimens were collected once a month except snowy season from Abashiri River basin, eastern Hokkaido, between June 2007 to November 2011. Fish were captured by the electrofisher (Smith-Root, Model 12-b). The estimated allometric coefficient b values ranged from 2.790 (ninespine stickleback ) to 3.294 (the sculpin), and r2 values ranged from 0.772 (lake minnow) to 0.994 (the goby). All the LWRs were highly significant, with p < 0.001. Besides, the study provides the first estimates of LWRs for the stone loach, Japanese smelt, masu salmon, whitespotted char, the sculpin, and the goby.
