How Are Cod Fish Raised on Farms?
Cod fish are raised on farms through a series of controlled processes. First, farmers select healthy broodstock, which are adult cod that will reproduce. They monitor these fish to ensure they are disease-free, as healthy parents contribute to strong offspring. Next, the broodstock is placed in tanks to spawn, where fertilized eggs are collected and carefully incubated.
After hatching, juvenile cod, called fry, are kept in low-density systems to reduce competition and promote growth. As the fry grow, farmers gradually increase the density of the tanks and provide a diet that includes high-quality fish feed. This feed contains the necessary nutrients, like proteins and vitamins, that cod need to grow.
Farmers also regulate environmental conditions such as temperature, salinity, and oxygen levels. They regularly test water quality and make adjustments to ensure an ideal habitat for the fish. As the cod reach maturity, typically in 18 to 24 months, they are harvested using nets or cages.
In summary, cod fish farming involves selecting healthy parents, spawning, careful rearing of fry, precise feeding, and managing environmental conditions. This systematic approach ensures that farmers can produce strong and healthy cod for market consumption.
