Rating summary

Data surrounding Rockall cod is limited. There is concern for both biomass and fishing pressure. The Rockall cod stock is at a very low level, although recent data indicate that it may be starting to increase. Landings have been above the advice since 2016, and fishing pressure is currently unknown related to reference points, therefore there is concern for fishing pressure. Landings of cod from this area in the 1980s-90s were relatively high, often between 1,500-2,000 tonnes. However since 2004 the landings have been consistently below 100 tonnes. This dramatic decline in landings is likely indicative of a depleted stock. Total Allowable Catches and landings are above recommended limits, although effort in the fishery has decreased since 2010. The main management measures relate to catch limits, which have been set significantly higher than scientific advice in recent years. Management is therefore not following scientific advice. Most Rockall cod are caught by otter trawls as bycatch, which is likely to cause some damage to the seabed. Bycatch is moderate and may include vulnerable species such as blue and flapper skate.Rating last updated August 2024.

Technical consultation summary

Data surrounding Rockall cod is limited. There is concern for both biomass and fishing pressure. The cod stock in this region has not been assessed and is classed as a category 6 stock - the most data deficient category. There are no biomass data, only landings, which have remained below 100 tonnes since 2004. The biomass for Rockall cod is currently unknown related to reference points and is believed to be at very low levels, therefore the biomass is of concern. Landings and Total Allowable Catch (TAC) have exceeded advice since 2016. In 2022, landings were approximately 80% above the scientific advice of 14 tonnes (71 tonnes), and in 2021 the catch was around 54% above advice (26 tonnes). The fishing pressure is currently unknown related to reference points. Due to lack of information and consistent catch above advice, fishing pressure is concern. The main management measures for Rockall cod relate to catch limits, which have been set significantly higher than scientific advice in recent years. Management is therefore not following scientific advice. Most Rockall cod are caught by otter trawls as bycatch, which is likely to cause some damage to the seabed. In this area, there are concerns that trawling could be affecting vulnerable marine habitats. Bycatch is moderate and may include vulnerable species such as blue and flapper skate.
