A relatively large pale sandy coloured ray with a short nose and short tail which is found in deep waters. Often marketed as skate wings. 


Sustainability Overview

Like all rays the sandy ray is a slow growing species that produces a small number of eggs each year, is vulnerable to over fishing and is easily by-caught in nets and trawls. This species is under studied and not common in Cornish waters.

Cornwall Good Seafood Guide rates fish on sustainability using a scale of 1 to 5.

1, 2 and 3 are recommended, Fish to avoid are rated 5.

We use the system devised by the Marine Conservation Society (MCS) so our scores are comparable with the scores produced by MCS for the UK and fisheries from all around the world. For more information on scoring click here.

Biology

The Sandy Ray is a large skate that can reach 120cm in length, but is most usually around 70cm. It has a short snout with a very pronounced tip and strong tail which is only slightly longer than the body. This is a little studied species that is found in deep water at depths of between 70 to 275m.

Stock Info

Classed as vulnerable by the ICUN red list.
This species has not been recorded in the Celtic sea by experimental trawling since 1997. Around 1 tonne of sandy rays are landed to Cornish ports each year (MMO data).
 

Management

All skates and rays are managed by a Total allowable catch quota system in EU waters. There is no specific management plan for demersal elasmobranchs and no management plan for this stock or any skate stock in the ICES area. Given the regional differences in skate assemblages and fisheries, ICES recommends that management measures for elasmobranchs be developed on a case-by-case basis.

Capture Info

Caught in beam trawls demersal trawls and gill nets. 
These fishing methods all have issues with by catch of non target species and impacts on the wider marine environment.
