The brown shrimp stock in the NE Irish Sea has been scored a low risk. This is because species is considered low vulnerability (www.sealifebase.org) and the catch rate indicator suggests stability.
The management of the North East Irish Sea brown shrimp fishery has been scored a high risk. There is some monitoring, but the information is not used to manage the fishery. .
The bycatch risk for the North East Irish sea fishery for brown shrimp has been assessed as a high risk. Around 60% of the catch is discarded 30% of which is small fish and 30% is small shrimp. Small shrimp are successfully riddled on deck and suffer around 20% mortality from this source when they are returned to the sea. So the total percentage of the catch suffering discard mortality is around 36% of the catch. As well as the on board riddles which effectively reduce the effects of fishing on small shrimp, there are mitigation measures in place principally aimed at reducing bycatch of fish larger than 10 cm.
The seabed effects of the North East Irish Sea fishery for brown shrimp are scored as low risk. The fishery uses light beam trawl gear in inshore areas where mobile sediments disturbed frequently by tidal and wave action which means that they are relatively invulnerable to disturbance by trawling. However, there are high risk habitats which are considered vulnerable to trawling and the North West Inshore Fisheries and Conservation Authority have protected areas in place and an ongoing process to improve protection of these habitats.
