Tiger trout can be produced reliably in hatcheries and they have been incorporated into stocking programs in the United States at least as early as the 1960s. [8] Hatchery productivity is enhanced by heat shocking the fertilized hybrid eggs, causing the creation of an extra set of chromosomes which increases survival rates from 5% to 85%. [9]
Historically, cutthroat trout was considered one species (Oncorhynchus clarkii).[2] [9] However, recent genetic, taxonomic, and geologic [10] evidence has determined that cutthroat trout should be divided into four species, with each (except for the coastal cutthroat) having multiple subspecies corresponding to the evolutionary lineages [11] found within major river basins.

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. The total volume required for a raceway is calculated by dividing the total amount of fish in kg by the desired stocking rate in kg per m 3. [17]
