Abstract:

Attempts to involve coldwater marine fishes into aquaculture were previously done repeatedly. However due to various reasons, this direction has been not properly developed. Meanwhile, it might be considered as very prospective one and there several main directions of its development. Fish farming: Cultivation of fish in marine environment allows taking commercial production of species that are rather rare in the wild or which meat has high market price (example sablefish Anoplopoma fimbria, skilfish Erilepis zonifer, Atlantic and Pacific halibuts Hippoglossus hippoglossus and H. stenolepis, rough scale sole Clidoderma asperrimum, thornyheads Sebastolobus spp., tooth fishes Dissostichus spp.). Stock enhancement: This direction of aquaculture aims to maintain abundance of populations exploited by fisheries at sustainable level or to help recovering of overfished stocks. For instance, such approaches to enhance Pacific cod Gadus macrocephalus stocks are used currently in Japan and Republic of Korea and might be considered as very promising. Completion of public aquariums exhibits: In public aquariums worldwide, as a rule, representatives of tropical ichthyofauna are mostly demonstrated. Meanwhile, there are many species among fishes of northern latitudes having bright coloration and exotic appearance (example Cyclopteridae, Agonidae, Zoarcidae, Cottidae, Hemitripteridae, Pholidae, Stichaeidae, Liparidae, Hexagrammidae etc.) that make their maintenance in public aquariums very attractive. Maintenance in research aquariums: The biology of variety of coldwater marine species remains poorly understood (example skates, snailfishes, poachers, sculpins, eelpouts etc.). Therefore maintenance of coldwater fish species in research aquariums has scientifically cognitive aspect.
