Selective Trawl Catch Data from Farne Deeps Nephrops Fishery Trials 2020-2021

Catch data from trials of a selective Net Grid trawl in the Farne Deeps Nephrops fishery during 2020-2021. The data was collected as part of the Fisheries Science Partnership programme to improve gear selectivity and help skippers adapt to the Landing Obligation. It includes quantities and sizes by species, along with positional and timing information for each sampling station.

Use Cases

• Evaluating the selectivity performance of different mesh sizes (100mm vs 200mm) based on catch separation data.
• Assessing the effect of artificial lights on fish separation between cod ends, as mentioned in the trial description.
• Analyzing species-specific length distributions to understand the impact of gear modifications on bycatch.
• Supporting the formulation of Discard Plans by demonstrating achievable selectivity improvements.

Strengths

• Data is part of a structured Fisheries Science Partnership programme, suggesting a formal research context.
• Description specifies collection of length distribution data for all species of fish at each station.
• Trials build upon previous studies conducted in 2019/20, indicating a longitudinal research effort.

Limitations

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