Do Hatchery Fish Spawn at Andre Lynn blog

Do Hatchery Fish Spawn. Relatively few hatchery fish successfully spawn in the wild, but those that stray from their hatchery location and make their way up a wild salmon stream may do more harm. The average size of fish has dropped not due to hatcheries, which are often designed to produce larger fish anyway, but due to lack of food on the ocean, and other poor ocean conditions, higher harvest rates in the ocean, all of which results in lower age class fish returning to spawn. In one early experiment, salmon that were reared in one stream and then moved to a hatchery during the smolt stage returned to the. Water temperature and light are very. And, like boats, hatchery fish are money pits. The role of the hatchery is very different from farm (numbers of appropriate size). Later in their lives, hatchery fish enter spawning grounds and interbreed with wild salmon, diminishing their genetic robustness. Hatchery facilities also directly harm wild fish and the surrounding environment, including by blocking wild fish passage to upstream spawning habitats and by discharging effluent that has been contaminated with pathogenic fungi, bacteria, parasites, effluent, and medical treatments.
