A Nordmore sorting grid, which has been required in the Gulf of Maine Northern shrimp (Pandalus borealis) trawl fishery since , was found to decrease bycatch of 8 groundfish species when observed tows before and after the grate requirement were compared. Catch rates of shrimp increased possibly due to higher catch rates of large shrimp. Discards of small northern shrimp (Pandalus borealis) are a problem in the Skagerrak northern shrimp trawl fishery. To reduce catches of small shrimp, we studied the effect of trawl belly length. fishing line of shrimp trawls by using longer toggle and chain lengths has also been tested and has reduced the catches of turbot and lantern fish. In Newfoundland's shrimp trawl fishery, toggle and chain lengths are required to be 71 cm ("). A shrimp beam trawl fishery has been developed in Fortune bay, on the south coast of Newfoundland.

Days out of the fishery – certain days during the fishing season are closed to fishing to slow catch rates and prolong the fishing season, or to make shrimp available when demand is greatest. Minimum mesh size in trawl nets to prevent bycatch of undersized shrimp. Requirement to use finfish excluder devices to reduce bycatch in the fishery. The Northern Prawn Fishery Industry (NPFI), including members from all stakeholders in the fishery, SCIRO and AFMA, monitors this. The stock is not considered overexploited. Bycatch / discards The main bycatch species are mainly forage fish. Bycatch of non-commercial species is very low, but includes some species listed in the IUCN Red list. In the South Atlantic, managed under the Shrimp Fishery Management Plan for the South Atlantic Region: Permits are needed to harvest shrimp in federal waters. Fishing trip reports must be submitted for each fishing trip. Observers must be carried aboard vessels if selected, to collect data on catch, bycatch, fishing effort, and fishing gear.
The temporal and spatial patterns of the ratio strongly support the seasonal and area closures implemented for the shrimp fishery in terms of bycatch bycatch-to-shrimp ratio of . Northern Shrimp: Flounder: This proposed project intends to investigate the use of floating bridles in the Gulf of Maine pink shrimp fishery and its effect on finfish bycatch reduction as well as reduced seabed impact. Click for more information. Field work complete. Currently analyzing data. Introduction. Pink shrimp (Pandalus borealis) is widely distributed in the northern portions of the Pacific, Atlantic, and Arctic (Shumway et al., ).Because small-mesh codends are used for harvesting the species, bycatch can be considerable (Howell and Langan, ).The use of the Nordmøre grid became mandatory in in the pink shrimp fishery in the Gulf of Maine and has proven to.
