Rating summary

In Irish Sea East, scampi, often referred to as Nephrops or Norway lobster, is data limited due to a lack of reference points. There is concern for the biomass, and no concern for fishing pressure. Some management measures are in place. Catch limits don't match the stock area, meaning there is a risk of overfishing, but current catches are within recommended limits. Trawling for Norway lobster can have an impact on seabed habitats, particularly on mud which is subjected to high disturbance by fishing. In this area, bycatch of Irish Sea cod and whiting is also of significant concern.Rating last updated: December 2023.

Technical consultation summary

In the eastern Irish Sea, scampi, often referred to as Nephrops or Norway lobster, is data limited. There is concern for the biomass, as in 2023 stock abundance declined to 191 million individuals, below the target level (MSY BTrigger, 350 million). There is no concern for fishing pressure as the total catch in 2022 was 274 tonnes. This is equivalent to a harvest rate of 2.8% of the population (by number). It is below the level associated with Maximum Sustainable Yield (FMSY, 11%), indicating that the stock is not subject to overfishing and therefore there is no concern for fishing pressure. Some management measures are in place. Catch limits don't match the stock area, meaning there is a risk of overfishing, but current catches are within recommended limits. Trawling for Norway lobster can have an impact on seabed habitats, particularly on mud which is subjected to high disturbance by fishing. A 2023 OSPAR report showed that 87% of offshore circalittoral mud has been subjected to high disturbance, suggesting that this habitat has not been suitably protected in this fishery. Disturbance from trawl gear on the seabed, especially over long periods of time, is likely to affect the structure, species composition, and biodiversity of the burrowed mud community. Bycatch in trawls may also be of concern and in this area, bycatch of Irish sea cod and whiting is also of significant concern.
