Rainbow trout can be trained to press a bar to get food, and they remember this three months after last seeing the bar. [23] Red Sea clownfish can recognize their mate 30 days after it was experimentally removed from the home anemone. [24] Several fish species are capable of learning complex spatial relationships and forming cognitive maps. [25]
The rainbow trout (Oncorhynchus mykiss) is a species of trout native to cold-water tributaries of the Pacific Ocean in North America and Asia. The steelhead (sometimes called steelhead trout) is an anadromous (sea-run) form of the coastal rainbow trout (O. m. irideus) or Columbia River redband trout (O. m. gairdneri) that usually returns to freshwater to spawn after living two to three years ...
Steelhead in 1924 illustration using the original taxonomic name, Salmo gairdneri The freshwater form of the steelhead is the rainbow trout (Oncorhynchus mykiss).The difference between these forms of the species is that steelhead migrate to the ocean and return to freshwater tributaries to spawn, whereas non-anadromous rainbow trout do not leave freshwater.
They also showed fin damage in the presence of brown trout, all of which suggests aggressive and territorial behavior by brown trout. [59] Non-native brook trout and rainbow trout have been stocked and transplanted throughout the native range of Rocky Mountain cutthroat trout, are widely established, and generally self-sustaining.

The rainbow trout has a steelhead subspecies, generally accepted as coming from Sonoma Creek. The rainbow trout of New Zealand still show the steelhead tendency to run up rivers in winter to spawn. [2] In Australia, the rainbow trout was introduced in 1894 from New Zealand and is an extremely popular gamefish in recreational angling. [3]

A study was performed by Wang et al. (2019) [26] to identify more potential Mx genes that resided in rainbow trout. An additional six Mx genes were identified in that study, now named Mx4-9. They also concluded that the trout Mx genes were "differentially expressed constitutively in tissues" and that this expression is increased during development.
