Tagging experiment of nototheniid fish, Trematomus bernacchii Boulenger under the coastal fast ice in Lutzow-Holm Bay, Antarctica

Based on the tagging experiment and size frequency analysis, growth pattern of nototheniid fish, Trematomus bernacchii BOULENGER, was studied under the coastal fast ice in the Kitano-ura Cove, Lutzow-Holm Bay, Antarctica. This species loses body weight during the overwintering and recovers the loss from spring through summer. Growth in body length takes place from summer to the middle fall probably after recovering the body weight loss in the dark season. The loss in the body weight seems to be also caused by spawning activities in early spring
