Description

The disparity of fishing pressure and available resource has prompted concerns regarding the impacts of competitive fishing events on fish resources and traditional sportfishing. These events tend to attract more anglers to the water bodies where they are held than might otherwise visit and a large portion of the total annual harvest of some species can be taken in just a few days. Although many events adopted a catch and release format to address the issue of increased fishing pressure, studies conducted in Alberta have shown that fish survival can be very low, and few competitive fishing events have total fish mortalities below 10%. Increased survival rates of released fish can be achieved by regulating where, when and how events are run, by instituting best management practices and by educating anglers on proper fish handling techniques.

Description

This wildlife status report looks at the pygmy whitefish, a small, slim whitefish in Alberta that has been collected in specific habitats from only two locations in the province: Upper Waterton Lake and a restricted portion of the upper Athabasca River. This report is part of the Alberta Wildlife Status Report series, which provides comprehensive summaries of selected wildlife species intended to be useful to those managing populations of species and their habitats, and to help identify species that may be formally designated as endangered or threatened.

Predator damage control in cultured fish

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,... More ≫

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.

The document briefly summarizes information on Northern Pike in Alberta and outlines the management strategies that have been adopted. Companion documents will provide additional information on northern pike and describe operational plans for the management and recovery of specific populations. This plan is presented in non-technical fashion to serve as public information; however, readers are encouraged to review scientific literature regarding this species.

Description

If your fish-rearing pond is constructed to allow the passage of water in and out of the impoundment, you need a permanent barrier restricting fish movement. Water passage could be from continuous flows, such as wells, aquifers and springs, or intermittent flows, such as annual runoff or flooding conditions.
