| Biology: |
The Murray cod is one of the world's largest freshwater fish (Ref. 6390). They live in a wide range of habitats, from clear, rocky streams to slow flowing, turbid rivers and billabongs (Ref. 27498). They are generally found in waters to 5 m deep, in sheltered areas with cover from rocks, timber or overhanging banks. Adult fish are carnivorous, having a diet of invertebrates, fish, amphibians and occasionally reptiles, birds and aquatic mammals (Ref. 27498). The young feed on zooplankton. Spawning takes place from spring to early summer. Murray cod are territorial, their 'territory' associated with a specific hole, snag (large woody debris) or area of a river or lake (Ref. 27498). Juveniles may undertake migrations (Ref. 6390). Threatened due to over harvesting and habitat loss (Ref. 58490). |
