Western Australian Salmon
Arripis truttaceus
Key differences: Historically considered the same species, Arripis truttaceus is now recognized as a distinct species found exclusively in Western Australia. Morphologically very similar to Arripis trutta, but genetic studies confirm separation. Arripis truttaceus generally has a more robust body and slightly different meristic counts (e.g., fewer gill rakers, slightly different fin ray counts), though these are difficult to distinguish without detailed examination. The primary differentiator is geographic range.
Arripis georgianus (Ruff/Tommy Ruff)
Arripis georgianus
Key differences: Smaller in size (typically up to 40 cm) and generally has a more compressed body. The spots on the flanks are usually more pronounced and often form broken lines. The overall coloration can be more brassy or golden, especially on the flanks. It also has a smaller mouth relative to its head size compared to Arripis trutta.
