This final report on the project describes data on stomach contents of major fish predators of the euphausiid Nyctiphanes australis.
The study has concluded that: size and stock of krill and its production can be calculated with some degree of confidence; major predators of adult krill can be identified though the greatest mortality, which occurs in the larval stages, is probably due to carnivorous zooplankters; and swarming by krill is of extreme importance in increasing the attraction of krill as food.
