Net Grid Trawl Modifications for Nephrops Fishery Selectivity Trials 2019/20

Field trial data from a Fisheries Science Partnership project to develop a selective Net Grid trawl with two cod ends. The project aimed to improve catch composition matching to quota allocations and reduce discards in the Farne Deeps Single Rig Nephrops fishery. The dataset likely contains positional, temporal, and species length distribution information recorded at each sampling station.

Use Cases

• Analyzing gear selectivity performance based on catch composition data mentioned in the description
• Modeling spatial and temporal fishing patterns based on recorded positional and time information
• Assessing length distributions of fish species to evaluate the impact of gear modifications
• Informing discard plan formulation based on trial results demonstrating selectivity improvements

Strengths

• Data originates from a structured Fisheries Science Partnership programme
• Field trials were conducted with a specific modified gear design (Net Grid trawl with two cod ends)
• The dataset likely includes multi-faceted information (position, time, species, length)

Limitations

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