Description

Proper nutrition is essential to the health of all animals, and fish are no exception. Recreationally cultured fish stocked at a reasonable density in a dugout or pond will obtain most, if not all, their nutrition from their environment. Depending on the ecology of each pond, this natural supply of food may include varied amounts of aquatic and terrestrial invertebrates, such as insects, worms, leeches and freshwater shrimp, as well as amphibians, minnows, plant material and microscopic plankton. However, fish that are found to be slow growing, small at harvest or were knowingly more densely stocked may need to be provided with prepared feeds.

Description

Birds, fish and mammals are known predators of cultured fish. Bird predation is the major source of fish loss at aquaculture facilities. Predatory fish can also be a major concern to fish stocks, followed by mammal predation to a much lesser extent. The diversity of Alberta’s aquaculture practices as well as the variety of predators means producers need to understand damage prevention and control techniques. These control measures may be used singly or in combination to alleviate predation problems.
