Introduction
Lake surveys measure Alberta’s fish populations for:
- abundance (number of fish)
- structure (ages and lengths)
As different fish species have different behaviours, different methods are required to get an unbiased sample and assessment of the integrity of fish populations.
In focus
Lake surveys - Overview
Fisheries biologists use lake surveys to gather information and assess the status of fish populations.
The Alberta government uses Fall Index Netting (FIN) to monitor walleye and northern pike populations.
This lake survey method uses standardized nets to assess Northern Pike, Walleye and other fish during the summer months.
Summer Profundal Index Netting
Fisheries biologists use Summer Profundal Index Netting to gather information and assess the status of lake trout populations.
