Rating summary

The sprat population in the English Channel is healthy and fishing pressure is within sustainable limits. There is no management plan but catches are within scientifically recommended limits. Most catches are by mid-water trawlers, with low or no bycatch and no impact on the seabed.Rating last updated May 2024.

Technical consultation summary

The sprat population in the English Channel is healthy and fishing pressure is within sustainable limits. Stock assessments for sprat in this area are carried out annually by the International Council for the Exploration of the Sea (ICES). In 2024, no reference point was defined for biomass. As a result, scoring for this rating has moved from Route 1 to Route 2 (data limited). Sprat has medium resilience to fishing pressure. The stock size indicator (biomass index) is based on annual pelagic surveys (the PELTIC survey). In 2023, it was 61,270t, which is comparable to the long-term average. Therefore, there is no concern for the biomass. The harvest rate has been less than 1% since measurements began in 2013, while MSY is set at 8.57%. In 2023 it was 0.0007%. Therefore, there is no concern for the fishing pressure.There is no management plan for sprat in the English Channel, but some measures are in place. TACs have been set in line with scientific advice since 2020. Catches are below TACs and have been consistently declining since 2016. There is no minimum landing size for sprat in this area, but small sprat are not generally marketable. The recent low landings are thought to be because there are too few large sprat in catches, leading to a short season for the UK fleet. An FMP for North Sea and Channel sprat is expected in 2024.English Channel sprat is mainly caught by small mid-water or pelagic trawlers, with low or no bycatch and no impact on the seabed. Fishermen find sprat by sonar search: they use the size and shape of the marks on the sonar to assess the likely composition of the shoals. They can usually distinguish between herring, sprat and mackerel. Sprat is an important prey species in the North Sea ecosystem. The implications of the environmental change for sprat and the influence of the sprat fishery on other fish species and sea birds are at present unknown.
