Record of fishes sampled in Kita-no-ura cove (Lützow-Holm Bay, East Antarctica) in January 2019

Continuous monitoring of fish fauna is important for evaluating effects of fisheries and environmental changes on the Antarctic marine ecosystem. In January 2019, we collected 52 individuals of 5 species of notothenioid species in Kita-no-ura cove, Lützow-Holm Bay, East Antarctica. The emerald rockcod Trematomus bernacchii was the most dominant (N＝39), while the sharp-spined notothen T. pennellii was the second most common species (N＝10). The number of T. pennellii was larger, but the number of T. hansoni (N＝1) was smaller than previous studies. The relationship between body weight and total length of T. bernacchii and T. pennellii indicated that the body weight of T. pennellii tends to be higher than that of T. bernacchii of equal total length. Body weight is in proportion to total length to the power of 3.23 (95% confidence interval: 3.003.46); therefore, the deviation from isometry, the power of 3.33, was not observed.
