Oneida Lake Fish Trawl Surveys from 1958 to Present

60 years of trawl survey data from Oneida Lake, New York, collected by the Cornell Biological Field Station. The dataset includes total catch, weight, and catch per unit effort for species like yellow perch and walleye, with sampling from 10 standard and 7 additional shallow water sites. Data collection has been supported by the Cornell University Brown Endowment and the New York State Department of Environmental Conservation.

Use Cases

• Modeling long-term fish population trends based on the 60-year time series.
• Analyzing species-specific catch and weight data for yellow perch and walleye.
• Studying spatial distribution of fish using the provided sampling site coordinates.
• Investigating age-structured population dynamics using the reported adult and young-of-year data.

Strengths

• Data collection spans over 60 years, providing a long-term ecological record.
• Includes sampling from 17 distinct sites (10 standard and 7 shallow water).
• Contains species-specific metrics like catch per unit effort for key species.

Limitations

• Weight data is not available for all species groups and time periods.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
