Testing Modifications to the Net Grid in the Farne Deeps Single Rig Nephrops fishery 2019/20 - Fisheries Science Partnership dataset https://portal.medin.org.uk/portal/start.php?tpc=009_CEFAS2bc2aa29-1249-487c-a719-b730a2662996 This work was carried out as part of the Fisheries Science Partnership (FSP) programme. The aim of this project was to further develop a selective Net Grid trawl with two cod ends to improve performance and enable skippers to better match their catch compositions to their quota allocations. The information from the trials will help skippers adapt to the Landing Obligation by avoiding unwanted fish in a fishery identified as having relatively high discard rates and will demonstrate to managers the level of selectivity improvement that is currently achievable to help formulate Discard Plans. The specific objective was to modify the escape area in the Net Grid to retain selected commercial species and minimise catches of unwanted fish. This was achieved by conducting field trials of a modified Net Grid trawl with two cod ends – a lower cod end to retain primarily the *Nephrops* and an upper cod end to retain and select for commercial fish. At each station sampled, shot and haul, positional and times information were recorded, and for all species of fish length distribution data were taken. 20201203 20201116
