Recent studies in the Drake Passage and west of Antarctic Peninsula suggest that fin whales feed primarily on krill Thysanoessa macrura, and humpback whales on Euphausia superba (Herr et al., 2016).
The superfamily Bopyrina included three families as Dajidae (parasitic in the incubatory chamber or on the dorsal surface of the Mysids and Euphosiids), Bopyridae (in branchial cavity or on the abdominal cavity of the Anomuran and Macrura) and Entoniscidae (in visceral cavity of Brachyura and Anomura) (Hartnoll, 1960).
We found that mayflies Baetia rhodani, Siphlonurus alternatus and Caenis macrura were more abundant in and below HPP dams.
Megalopae were fed daily once with Moina macrura and newly hatched Artemia nauplii maintaining cell densities at 3 numbers/mL and 5 numbers/mL, respectively and twice daily with freshly prepared egg custard at the rate of 0.5 g/1000 L of water.
