Sustainability rating five info

Sustainability overview

The stock status is unknown. However, populations are lower than years previous.

Smalleyed rays caught in area 7e must be promptly released and scientific advice is to reduce landings by 20% in 2017 and 2018. Apart from this, there is no specific management plan for skates and rays in these waters but there is some improved management in inshore waters. They are managed under a total allowable catch (TAC) for many skates and rays but greater protection is needed.

Bycatch in fixed nets can include a variety of species but causes generally low impacts to the habitat. Ghost fishing is occasionally reported.


Small-eyed rays belong to the Rajidae family which includes skates and rays. They are a small to medium sized inshore and coastal species, attaining a maximum length of 80 to 90 cm and weight of 8 kg. Total length at maturity is between 69 and 78 cm. Age at maturity is unknown. Maximum age is 12 years.

Stock information

The state of the stock in this area is unknown. In the last 2 years, the population is estimated to be 27% below the preceding five-year average. Meanwhile, fishing mortality is unknown but may be increasing.

Scientists advise that landings should be reduced to 36 tonnes in 2017 and 2018. The species must be returned promptly to the sea when caught in area 7e. The IUCN have rated the species as “Near Threatened” in the Northeast Atlantic.

There are no management plans or objectives for this species. Skates and rays are managed under five regional quotas (called TACs) applied to a group of species. This has been deemed as an unsuitable method for protecting individual species, but species-specific quotas may not be suitable because it may increase unnecessary discarding of skates and rays.

Other management methods are currently being considered at an EU level. Methods to avoid catching rays include closed areas and seasons and modifying fishing gear to observe their escape behaviour and design fishing gear accordingly. However, it is difficult to avoid catching rays in fishing gear (because of their peculiar shape) so fishing gear modifications have been suggested to improve the potential survival of rays so that they can be quickly and safely discarded.

There is no official minimum landing size for many skates and rays outside the 6 nautical mile limit in European waters. However, some inshore areas mandate a minimum landing size (40-45 cm disc width). There is direct management of fishing effort, depending on fishing gear, mesh size and area, however, this only applies to vessels of >15 m and therefore, inshore (generally smaller) fleets are generally not effort managed to the same extent. There are catch composition rules limit the percentage of skates that can be landed by demersal otter trawls (dependent on the mesh size of the net).

More information is needed on skate and ray catches, discard and survival rates. Landings data doesn’t tell scientists much about the health of the stock. The Fisheries Science Partnership project connects fishermen and scientists to fill in important knowledge gaps.

Surveillance legislation is underpinned by EU Law, and requires all vessels above 12m in length use vessel monitoring systems (VMS), and mandate at-sea and aerial surveillance and inspections of vessels, logbooks and sales documents.

Some protected areas have been designated in these waters but offshore areas are not sufficiently managed. Some of these MPAs are designated to protect rays such as the Offshore Overfalls MCZ which is designated partly to protect the undulate ray’s nursery areas. The inshore waters, such as the Isle of White SAC, ensure management, which may provide protection for various life stages e.g. undulate rays. Although the connectivity of these species is unknown and therefore, these waters need sufficient management and protection to prevent over-exploitation of these animals and their habitats.

Capture Information

Criterion score: 0.5 info

Smalleyed rays in this area are caught mainly using bottom trawls and fixed nets.

Common bycatch in fixed nets include lesser spotted dogfish, nursehound and Starry ray. However, catches in gillnets are often not monitored and they are not very selective gear. Therefore, the net can interact with a wide range of fish, skates and rays, invertebrates, birds and marine mammals.

Since skate and rays are a peculiar shape and size, it is difficult for them to escape from fishing gear once caught. Therefore, other methods must be used to increase their likelihood for survival: skates and rays are generally a hardly species but their survival rate after discarding is extremely variable depending on fishing and handling methods: discard survival from gill nets after 2 days is 88% whereas its about 25%-100% survived in beam trawl surveys.

Smalleyed rays are normally found on mixed sediments and rock or hard substrates, therefore, gillnets generally cause low impacts to the habitat, although ghost fishing is reported occasionally.
