How we worked out this Rating

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.
