Studies on the digestion of krill by Notothenia rossii marmorata, Notothenia neglecta, Champsocephalus gunnari and Chaenocephalus aceratus showed that these Antarctic fish species are well equipped to feed on krill, as indicated by their high levels of chitinase and protease activity. Very high chitinolytic activities were determined in the stomach of the fish species. However, activities that were measured in intestine samples can be substantial, as well. Very strong protease activities were determined in samples of the stomach tissue and the intestinal contents. When krill were present in the guts, the concentrations of fluoride in the stomach and intestinal contents of N. rossii marmorata and Ch. gunnari were extremely high, while the tissues were practically devoid of fluoride.
对大理石纹南极鱼、裸眼南极鱼、冈氏头带冰鱼和长头冰鱼对磷虾消化情况的研究表明，这些南极鱼类具备捕食磷虾的良好能力，其几丁质酶和蛋白酶活性水平较高即表明了这一点。在这些鱼类的胃中测定出了非常高的几丁质分解活性。然而，在肠道样本中测得的活性也可能相当高。在胃组织和肠内容物样本中测定出了非常强的蛋白酶活性。当磷虾存在于肠道中时，大理石纹南极鱼和冈氏头带冰鱼的胃和肠内容物中的氟浓度极高，而其组织中实际上不含氟。
