Fish stocking is the practice of releasing fish that are artificially raised in a hatchery into a natural body of water (river, lake, or ocean), to supplement existing wild populations or to create a new population where previously none exists. Stocking may be done for the benefit of commercial, recreational or tribal heritage fishing, but may ...
The National Fish Hatchery System (NFHS) was established by the U.S. Congress in 1871 through the creation of a U.S. Commissioner for Fish and Fisheries. This system of fish hatcheries is now administered by the Fisheries Program of the U.S. Fish and Wildlife Service (Service), an agency within the United States Department of the Interior.

This year, the Fish and Boat Commission reduced its annual stocking by about 20% as it works on a plan to raise more fish solely in the Lake Erie water basin. “This year, the numbers were a ...
The Salmon River is a small river north of Syracuse in Upstate New York, the United States. [2] It is a popular and economically important sportfishing destination, and the most heavily fished of New York's Lake Ontario tributaries. [3] From its headwaters in the Tug Hill region of New York, it flows 44 miles (71 km) westward through two ...
Brook trout. The brook trout (Salvelinus fontinalis) is a species of freshwater fish in the char genus Salvelinus of the salmon family Salmonidae native to Eastern North America in the United States and Canada. [3][4] Two ecological forms of brook trout have been recognized by the US Forest Service. [3] One ecological form is short-lived ...
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]
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]
