Distribución y estructura poblacional de la polaca (Micromesistius australis)
The polaca (Micromesistius australis)is a typical fish from the cold Malvinas current (temperatures between 3° and 10°C). The species is found in depths between 90 and 800 m and in latitudes from 37°40' to 50° S during winter and spring and from 42°S to 55°S during summer time, over the patagon...
