Other biological data:
The pollock is a partial asynchronous player with very low fertility. The setting is south of 42 º S, from December to mid-March, outside of the guns. Through monthly analysis of the distribution of their larvae, two areas of parenting: 42 to 47 º S, April-May and north of 42 º S.
The food is predominantly fish (hake, nototénidos, pollack, hagfish, zoárcidos). Them still, in order of importance, cephalopods (squid and octopus), crustaceans (crabs, amphipods, isopods, etc.) and other agencies responsible, such as polychaetes.
