About the Trout Cod

Trout Cod (Maccullochella macquariensis). Found in Upper Murray River. Average length 24 in, weight 8.0 lbs. World record: 25.0 lbs (Victoria, Australia).

The Trout Cod is one of the most recognizable freshwater species in North American waters, classified scientifically as <em>Maccullochella macquariensis</em>. It belongs to the Australian group, most commonly found in upper murray river environments. Anglers target this species for both sport and table fare, and it appears across a broad range of water bodies throughout the United States.

A typical Trout Cod runs 24 inches in length and weighs around 8 pounds, though fish in prime habitat regularly exceed these averages. The all-tackle world record stands at 25 lbs, set at Victoria, Australia, making it a legitimate target for anglers chasing personal bests. Conservation status varies by region — check local regulations before keeping fish, as some waters have slot limits or catch-and-release requirements in place.

Habitat & Range

Primary habitat: Upper Murray River.

The Trout Cod thrives across a wide range of freshwater environments throughout North America. Seasonal movements are driven by water temperature — fish tend to move into shallower water during spring and fall feeding periods, and push deeper or seek cover during the heat of summer and cold of winter. Understanding these patterns is critical to locating fish consistently across the season.

How to Fish for Trout Cod

Best bait: Lures.

Technique: Casting.

Match your presentation to the season and conditions. In clear water, downsize your bait and slow your retrieve. In stained or muddy water, switch to high-contrast colors and add vibration. Early morning and evening are the most productive windows during summer months. During spawning season, fish become highly territorial and will strike out of aggression as well as hunger.

World Record

The all-tackle world record Trout Cod weighed 25 lbs, caught at Victoria, Australia. This record represents the upper end of what this species achieves under ideal conditions.
