Raceway setup cost and trout seed sourcing.
2 Answers
Trout is usually farmed in concrete or built raceways fed by gravity from a cold stream or spring, and the cost depends on the raceway size, water diversion channel and inlet works, so it varies a lot by site and terrain. A small farm can start modestly where natural water flow is available, while larger units cost more. The big advantage is that gravity fed flowing water reduces the need for pumps and power compared with other systems. For seed, trout fry, fingerlings or eyed eggs are usually supplied by government trout hatcheries and fisheries departments in the hill states, since reliable trout seed sources are limited. Get the raceway design, cost estimate and seed supply arranged through your state Fisheries department, which supports trout farmers in these regions.
The gravity fed water meant I did not need pumps, which kept running cost low. I got my fingerlings from the government trout hatchery since private seed is hard to find here.
