Reproduction and egg guarding by Atlantic wolffish ( Anarhichas lupus: Anarhichidae) and ocean pout ( Macrozoarces americanus: Zoarcidae) in Newfoundland waters
The reproductive season, the sex that provides parental care, and the relationship of feeding with reproduction are reported for Atlantic wolffish and ocean pout in eastern Newfoundland. Both species move into shallow water in the spring, pair during the summer, and spawn in holes under and between...
