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 ...

The genus contains twelve extant species, namely six species of Pacific salmon and six species of Pacific trout, all of which are migratory (either anadromous or potamodromous) mid-level predatory fish that display natal homing and ...
The aim of the dialogues was to produce an environmental and social standard for farmed salmon and other species (12 species currently, as of 2018). Since 2012, the standards elaborated by the multi-stakeholder Dialogues were passed-on to the Aquaculture Stewardship Council (ASC) which was created in 2010 to administer and developed them further.

There are currently 15 DPS for steelhead (Oncorhynchus mykiss) and 31 evolutionarily significant units (ESU) for five species of Pacific salmon Oncorhynchus. The boundaries of these areas are used to determine whether specific populations of a species should be designated threatened or endangered species under the Endangered Species Act.
