Rating*****
Alfonsinos or golden eye perch
Beryx spp.
REASON TO AVOID
Because of its aggregating behaviour this deep-water species is susceptible to exploitation. Insufficient information is available to suggest that current levels of exploitation are sustainable, as fishing in international waters is generally unregulated.
