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 limited data on the striped red mullet population (or stock) in this region and fishing pressures are above advised limits. Route 2 scoring has been applied to this rating owing to the lack of reference points for fishing pressure and biomass. Striped red mullet has a medium resilience to fishing pressure.This population (or stock) is data limited. The information available is insufficient to evaluate stock trends and exploitation. The only available data is landings data, which is not a good indicator of fishing mortality or biomass because it does not account for changes in fishing effort or catchability. In the absence of information there is concern for the population (or stock) biomass.Between 1975 and 2007 landings significantly increased, since a general decline in catches has been observed. Recent landings (1,973 tonnes in 2019, 1,445 tonnes in 2021 and 1,691 tonnes in 2022) have been above advised catch limits (1,600 tonnes in 2019, and 1,280 tonnes in 2021 and 2022) and the 5-year average (2018-2022). Moreover, for stocks without information on abundance or exploitation, ICES considers that a precautionary reduction of catches should be implemented unless there is supporting information clearly indicating that the current level of exploitation is acceptable for the stock. The precautionary buffer was last applied in 2020 and has been applied again in 2023. Consequently, there is concern for fishing pressure. ICES advises that when the precautionary approach is applied, landings should be no more than 1,024 tonnes in each of the years 2024, 2025, and 2026.
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.
