Abstract: Spotted catfish, Anarhichas minor Olafsen, were sampled from long\nline and trawl catches taken along the coast of Finnmark, near Bear\nIsland and in the Barents Sea in 1953 and 1954. Age was determined\nfrom vertebraes. Fish younger than 6 years were not found in the\nlong line samples. The age groups 12-14 were most abundant in\nthe long line samples taken off Finnmark as against 8-9 years old\nfish dominating the samples taken near Bear Island.\nThe females were found to attain sexual maturity at an age of\n6-7 years and a length of about 75 cm and the males approximately\none year later at a length of 80-85 cm.\nThe present study indicates that the spotted catfish spawn in\nJuly-August.\nIn 1953, 1954 and 1955 a total of 432 catfish were tagged with\nLea Hydrostatic tag. Until January 1963 71 were recaptured. The\nseasonal distribution and migration of the catfish are discussed.
