Due to concerns over declining burbot populations in the Kootenay Region, a study was initiated by the BC Ministry of Environment to provide better information on which to base regulations. The purpose of the study was to assess the population abundance and biological characteristics of burbot in four East Kootenay Lakes: Moyie, St. Mary, Columbia and Windermere. This work builds upon initiatives by Ministry of Environment staff in
September 2005 on St. Mary and Moyie Lake burbot populations.

The purpose of this study was to assess the abundance and biological characteristics of
burbot populations in four East Kootenay Lakes: Moyie, St. Mary, Columbia and Windermere (Figure 1.1.1). Each population chosen for this study has (or had) a popular sport fishery for burbot and is readily accessible to anglers. It was hypothesized that currently, burbot stocks are severely depressed in St. Mary, Columbia and Windermere Lakes but are relatively healthy in Moyie Lake. The objectives for work in 2006 were to
estimate:
1. Mean catch per unit of effort (CPUE) of burbot in four lakes as an index of abundance;
2. Abundance of burbot in Moyie Lake;
3. Mean total length, length at age, and parameters in the length-weight relationships of
burbot in the four lakes and;
4. Comparison of catch success between two trap styles (hoop vs. cod).
This work builds upon sampling by Ministry of Environment staff in late 2005 on St. Mary
and Moyie Lake burbot populations and utilizes techniques developed in the West Kootenay
for burbot stock monitoring (Neufeld and Spence 2004).
