Maccullochella is a genus of large Australian predatory freshwater fish within the Percichthyidae family. The Maccullochella genus was named after an early Australian fish researcher with the surname McCulloch.
The Maccullochella species are called 'cod' in the vernacular.
At the time of European settlement of Australia, members of the Maccullochella genus dominated the Murray-Darling river system (Murray cod, M. peelii, and trout cod, M. macquariensis) and 4 East Coast river systems (eastern freshwater cod, M. ikei, of the Clarence and Richmond Rivers, Brisbane River cod, Maccullochella sp., and Mary River cod, M. mariensis).
As large, long-lived, top-order predators with delayed sexual maturity and relatively low fecundity (fertility) Maccullochella species are extremely vulnerable to overfishing, siltation and other forms of habitat degradation, and river regulation by dams and weirs that alter river environments and negatively affect spawning and recruitment (survival) of young fish.
The Maccullochella species have not fared well since European settlement. All are endangered or critically endangered except for Murray cod, which are considered 'Threatened' and 'Vulnerable' under national and state legislation. There are grave concerns over the future of wild Murray cod now, as there for all the Maccullochella species.
- Maccullochella ikei — Eastern Freshwater Cod, Richmond River Cod
- Maccullochella macquariensis — Trout Cod
- Maccullochella peelii — Murray Cod
- Maccullochella mariensis — Mary River Cod
As of 2010 Mary River Cod are recognised as a fully separate species (Maccullochella mariensis) (Nock et al., 2010).
