Previous research conducted in Norway (since 1992) and Canada (since 2000), focused on identifying key biological parameters for spotted wolffish cultivation which led, respectively, to the rapid establishment of a full commercial production line in northern Norway, while Québec (Canada) is witnessing its first privately driven initiative to establish commercial production of spotted wolffish on its territory. The first artificially fertilized spotted wolffish (Anarhichas minor) eggs hatched in Norway in the mid-1990s as this species was considered by Norwegian authorities to be a top candidate species for cold-water aquaculture in the North Atlantic regions. corti infestations in captive wolf-eel populations should include fresh or brackish water treatments. A third experiment found that exposure to brackish water (19 parts-per-thousand salinity) for 16 days was efficacious when compared to seawater controls (30 ppt). Although efficacious, formalin is carcinogenic, lessening its suitability as a treatment option. The efficacy of freshwater baths (5 or 8 min duration) was less than that of formalin, but better than observed in the groups receiving 30 minute baths in hydrogen peroxide (150 or 200 mg/L). Sixty minute baths in formalin (150 or 200 mg/L) were found to be the most efficacious treatment with lower mortality and mean parasite intensity when compared with the other treatments. Exposures to formalin, freshwater or hydrogen peroxide were compared for efficacy against the parasite in two experiments. Gyrodactylus corti is a parasite which causes disease and elevated mortality in captive populations of the wolf-eel (Anarrhichthys ocellatus).
