In the early 1950s, John E. (Red) Hanson, while working for the New Mexico Game and Fish Department, began experimenting with dietary routine and dry pellet formulations. The first fish feed pellets were introduced to hatchery trout at the Red River Hatchery near Taos. The pellets resulted in improved conversion rates of food intake to fish ...
Rainbow trout, including juvenile steelhead in fresh water, routinely feed on larval, pupal, and adult forms of aquatic insects (typically caddisflies, stoneflies, mayflies, and aquatic dipterana). They also eat fish eggs and adult forms of terrestrial insects (typically ants, beetles, grasshoppers, and crickets) that fall into the water.
Expressing eggs from a female rainbow trout. The cost of inputs per unit of fish weight is higher than in extensive farming, especially because of the high cost of fish feed. It must contain a much higher level of protein (up to 60%) than cattle feed and a balanced amino acid composition, as well.
The rainbow trout (Oncorhynchus mykiss) is a species of trout native to cold-water tributaries of the Pacific Ocean in North America and Asia.

For rainbow trout, poorer growth rates were found when S. polyrhiza was added to the feed. [19] For tilapia (Oreochromis niloticus L.), greater weight gains were found when 30% of the fish meal in the feed was replaced with S. polyrhiza. [20] A review has also shown that duckweed can be used in cattle, pig and poultry diets.
"Rainbow trout love cold water and can be caught on a variety of baits and lures (worms, commercially available pastes, corn, spinners, spoons, flies and more), and are great to take home and eat.
They compiled their research into a 255-page report on United States fish resources. Congress granted the team $15,000 to develop food fish stocks, and non-native fish such as rainbow trout, salmon, striped bass and carp were subsequently introduced successfully into United States lakes and rivers.
