The maximum load of organisms that can be cultured in a raceway system depends on the species, and particularly on the size of the species. For trout, stocking rates of 30 to 50 kg/m 3 are normal at the end of a rearing cycle, while for marine species, such as sea bass and sea bream, the achievable load is lower, between 15 and 20 kg/m 3.
Trout have been reared artificially for over 80 years. [23] Rainbow trout broodstocks are commonly manipulated to delay maturation and spawning time in order to provide eggs regularly and optimise supply. [5] Artificial selection has favoured larger fish due to evidence of correlations between fish size and fecundity. [15]

For warm water ponds, it is recommended to stock largemouth bass, bluegill, crappie, channel catfish, and bullheads. For larger and deeper lakes, stocking cool water game fish such as walleye and trout species is recommended. [20] Lastly, it is important to make sure that no pond or body of water is overstocked.
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 silver trout (S. agassizii or S. f. agassizii) is an extinct trout species or subspecies last seen in Dublin Pond, New Hampshire, in 1930. [20] It is considered by fisheries biologist Robert J. Behnke as a highly specialized form of brook trout.
