Lake Winnipeg Pelagic Fish Trawl Survey with Seasonal and Basin Data

Fisheries and Oceans Canada conducts pelagic trawl tows at lakewide monitoring stations to study fish assemblages in Lake Winnipeg. The survey, active since 2002, collects samples during spring, summer, and fall from the south basin, channel, and north basin to analyze species biomass estimates across seasons and geographic regions.

Use Cases

• Analyze species biomass estimates across the south basin, channel, and north basin to study geographic variation within Lake Winnipeg.
• Model temporal patterns in fish assemblages using seasonal data collected during spring, summer, and fall since 2002.
• Study the effects of season on pelagic fish community composition using trawl samples from lakewide monitoring stations.

Strengths

• Data collection spans over two decades, with surveys conducted since 2002.
• Samples are collected from three distinct geographic regions: the south basin, channel, and north basin of Lake Winnipeg.
• Survey design includes seasonal coverage with samples taken in spring, summer, and fall.

Limitations

• The specific number of rows, columns, and total sample size is unknown.
• Data is limited to offshore pelagic trawl tows and may not represent nearshore or benthic fish communities.
• The dataset's spatial coverage is confined to Lake Winnipeg, limiting broader ecological inferences.
