How we worked out this Rating
Stock status
The size and health of a fish population, or 'stock', that is being targeted by fishermen is a crucial indicator of whether a fishery is sustainable. If the stock is too small to withstand fishing, it is at risk of crashing. We look at how big the stock is, and how much pressure there is from fishing, to assess this. The target level that many fisheries aim for is 'Maximum Sustainable Yield' - the most fish that can be caught year after year whilst keeping the population at a healthy size.
There is concern for the biomass of shagreen ray in the Celtic Sea and West of Scotland, and concern for the fishing pressure.Route 2 (data limited) scoring has been applied to this rating owing to the lack of reference points for biomass and fishing pressure. Shagreen ray is considered to have a low resilience to fishing pressure.There is no information available about abundance of this stock and therefore, there is concern for biomass.There is also a lack of information on fishing pressure, landings have been stable over the last couple of years, but are exceeding advice. Therefore, there is concern for fishing pressure.ICES advises that when the precautionary approach is applied, landings should be no more than 134 tonnes in each of the years 2023 and 2024. This is a reduction of 20% from the advice for 2021 and 2022. It is unknown whether the current level of exploitation is appropriate for the stock and therefore the precautionary buffer has been applied.
Management
Good management is vital to be sure that fishing doesn't cause fish populations to decline. We look at whether regulations follow the best available scientific advice, how well compliance is monitored and enforced, and whether this is effective in maintaining healthy fish stocks.

Capture method
Environmental impacts of fishing vary hugely, depending on the method used and where it's happening. We look at whether the fishing gear being used could have an effect on seabed habitats, and if so, how severe might this be. We also review whether it catches any other species by accident (bycatch), and what effect this might have on those species - especially if they're Endangered, Threatened, or Protected.
