AMAR 2/01: Solent Bass Pre-recruit Survey Catch Data from 2001

A 2001 survey conducted by the Centre for Environment, Fisheries & Aquaculture Science (Cefas) aboard the Angelle Marie from September 5 to 9. It is part of a long-term series started in 1983, aiming to provide abundance indices for 2-4 year old bass and record catch densities of other species. The survey operated at 42 stations using an otter trawl and recorded 65 different species.

Use Cases

• Modeling bass recruitment indices based on the survey's focus on 2-4 year old fish.
• Analyzing multi-species catch composition and density from the 65 recorded species.
• Studying temporal trends in fish populations by comparing this survey to others in the series from 1983 onward.
• Assessing the impact of specific fishing gear based on the described otter trawl specifications.

Strengths

• Part of a long-term survey series with over 50 surveys dating back to 1983, enabling time-series analysis.
• Specific operational details are provided, including the vessel (Angelle Marie), dates (05/09/2001-09/09/2001), 42 stations, and gear specifications.
• Records a broad biodiversity snapshot with 65 different species caught.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• Last update date is unknown; freshness unverified.
