1985
Wim Vader | Kirsi Romppainen
The dominant group of carrion-eating amphipods in Norway are the Lysianassoidea; they play an important role as scavengers in Norwegian and arctic waters. A number of genera damage fish caught in nets and on long-lines; in Norway the most serious damage is done by Anonyx and Tmetonyx species. Tmetonyx cicada and the isopod Cirolana borealis have also regularly been found in Cod roe. Symbionts of living fish belong to the genera Lafystius, Normanion, Opisa and Trischizostoma. Lafystius and Normanion have low host specificity, Opisa eschrichtii is found on gadids and Halibut Hippoglossus hippoglossus and Trischizostoma raschi on the small shark Etmopterus spinax. Little is known on the biology of these species.
