Description
Summary:Antarctic nototheniid fish, Trematomus bernacchii and Pagothenia borchgrevinki were reared in the aquarium at the Kamogawa Sea World, Japan. Two T. bernacchii and 4 P. borchgrevinki individuals survived for about 2000 days in good condition. Growth in the body length and body weight of both species was observed. One individual of T. bernacchii spawned once a year since 1984. During about 1 month before spawning the fish stopped feeding. The similar behavior in feeding was observed in the other individual of T. bernacchii.
