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

The purpose of this publication is to provide information regarding greenhouse management. It presents basic indicators to help growers evaluate the plant-environment interaction as they move towards optimizing the environment and crop performance. Over time and with experience, growers will be able to build on their understanding of these basic indicators to improve their ability to respond to changes in the crop and to anticipate crop needs.

Predator damage control in cultured fish

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.

Description

The information in this fact sheet was prepared five decades ago by Dr. J.T. Slykhuis and Dr. J.E. Andrews at the Agriculture Canada, Lethbridge Research Station. With a few minor revisions, all their virus control information is as valid now as it was then. Wheat streak mosaic, which is probably native to southern Alberta, was first recognized here in 1952. In both 1952 and 1953, wheat streak mosaic caused severe damage to a number of winter and spring wheat crops. It did so again on winter and spring wheats in 1992 in the Claresholm to Mossleigh area. This disease can be controlled or reduced to a minimum by following certain cultural and agronomic practices. The following information is provided to answer some of the questions being asked by farmers about wheat streak mosaic and to suggest methods for its control.
