The Role of Fish as Predators of Krill (Euphausia superba) and Other Pelagic Resources in the Southern Ocean
Abstract: First attempts were made in the early 1980’s to estimate the krill and pelagic food ... number of food studies were conducted. Currently, the best estimates of krill consumption by fish are 23 ... – 29. 106 tonnes of krill and other pelagic prey taken annually by demersal fish and 7 – 44. 106 tonnes ... quantitative winter food studies. However, it is evident from this review that the importance of krill in fish ...
