Fishery Resources and Habitats in Brock Lake, Northwest Territories, 2003-2005

Brock Lake in the Northwest Territories was sampled during a winter subsistence fishery in November 2003 and assessed physically, chemically, and biologically in July 2004 and July 2005. The data includes physical, chemical, and biological variables and is documented in a Canadian manuscript report. It was published by Fisheries and Oceans Canada and is available under an open government license.

Use Cases

• Analyze seasonal changes in lake conditions based on winter and summer sampling periods.
• Study the relationship between physical/chemical variables and biological resources mentioned in the description.
• Model habitat suitability for fish species in a headwater lake environment.
• Assess the impact of subsistence fishing activities on a northern lake ecosystem.

Strengths

• Data collection spans multiple seasons (winter 2003 and summers 2004, 2005).
• Variables cover physical, chemical, and biological aspects of the lake ecosystem.
• Data is documented in a formal scientific report (Can. Manuscr. Rep. Fish. Aquat. Sci. 2932).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the specific sampling years (2003-2005).
