Found 10 records similar to Lake Trout Catch Per Unit Effort - Kluane
Effort, catch, and biometric fish data are produced using the Summer Profundal Index Netting (SPIN) methodologies developed by the Ontario Ministry of Natural Resources. Monitoring is generally conducted generally on a five year cycle, with additional sampling as necessary. Data are from Kingsmere Lake, where the majority of the park’s recreational lake trout fishing occurs. This monitoring allows the park to collect data on the size, structure and physical condition of the lake trout population.

Brook trout are top predators in aquatic ecosystems at Kejimkujik that integrate the effects of stressors throughout the aquatic trophic structure. They are sensitive to a variety of stressors, including acidification, changes in water quality, climate change, fishing pressure, exotic species introductions, trophic structure alterations, land use change, and watershed fragmentation. The monitoring program tracks Brook trout population status, as assessed by relative abundance and trout condition at two watersheds in Kejimkujik. Volunteer anglers record morphometric and catch per unit effort data during the months of April, May and June for 3 years in a row every 5 years.
This dataset shows the locations of westslope cutthroat trout of non-stocked pure strain populations with average DNA purity ≥ 0.99%. This species is listed as threatened under the Species at Risk Act.
Acute and chronic toxicity and modes of action of benzotriazoles (BZTs) and benzotriazoles UV-stabilizers (BZT-UVs) were evaluated in freshwater invertebrates, algae, and fish. Gene transcription, life history (viability, growth, reproduction), and protein activities were measured after short and long-term exposure of the freshwater crustacean Daphnia magna, the freshwater algae Chlamydomonas reinhardtii, and the rainbow trout (Oncorhynchus mykiss) to each compound alone and in a mixture.
Contained within the 4th Edition (1974) of the Atlas of Canada is a set of nine maps showing the ranges of principal commercial freshwater fish including walleye and sauger, white bass, northern pike, yellow perch, arctic char, lake sturgeon, lake whitefish, lake trout and rainbow smelt.
The study examines the parasite communities in Athabasca River Trout-perch (Percopsis omiscomaycus) at five sites along the main stem of the Athabasca River to explore whether any observed changes in parasite abundance or community structure might correlate with small-scale variations in water chemistry, sediment characteristics, water and sediment pollution, larger-scale landscape use patterns, distance among sites, and upstream-downstream gradients.
Annual fish monitoring data for 20 lakes across Canada. Collection season was standardized to provide temporal comparability within each lake. In most lakes, fishing occurred in the fall. Predator fish were limited to trout, pike or walleye, to facilitate spatial comparisons.
Water temperature is considered a key ecosystem driver in freshwater ponds and streams of PEI National Park. American eel and Eastern Brook trout have been chosen for evaluating pond and stream temperature conditions as they are a common residents in most Atlantic Canada water bodies. Eastern brook trout are intolerant of warm water conditions. Stream temperature and brook trout growth are important factors that can directly influence survival, growth and distribution.
This dataset contains Lake Ontario prey fish abundance and distribution statistics, collected every year during spring and fall bottom trawl surveys. The New York State Department of Environmental Conservation and the U.S. Geological Survey have conducted annual, spring and fall bottom trawl surveys in U.S. waters of Lake Ontario since 1978. In 2015, the Ministry of Natural Resources and Forestry started contributing to this program to include survey coverage in Ontario waters. The ministry also intermittently conducts mid-water trawling during the summer months on a limited geographic area largely confined to the Eastern Basin.
