Fourhorn Sculpin

 

(Myoxocephalus quadricornis), a fish of the family Cottidae. The fish measures as much as 37 cm in length and reaches 500 g in weight. Two pairs of bony protuberances on the head are highly developed in ocean forms and poorly developed or absent in lake forms.

The fourhorn sculpin is distributed along the shores of the northern Arctic Ocean, the Baltic Sea, the lakes of Northern Europe, and the Great Lakes of North America. It feeds on crustaceans and fish. It reproduces in winter. The fish is edible but has no commercial importance.

We analyzed abundance indices, as logetransformed catch-per-unit-effort (CPUE), of four marine species (arctic cod, Boreogadus saida; fourhorn sculpin, Myoxocephalus quadricornis; arctic flounder, Pleuronectes glacialis; saffron cod, Eleginus gracilis); two freshwater species (round whitefish, Prosopium cylindraceum; arctic grayling, Thymallus arcticus); and the anadromous rainbow smelt, Osmerus mordax, to determine whether there were increases in the abundances of marine species and declines in anadromous and freshwater species.
