Top Alfonsino Fishing Countries

The alfonsino (Beryx decadactylus) is a deep-sea fish prized for its firm, white flesh and is commonly found in temperate and subtropical waters of the Atlantic, Indian, and Pacific Oceans, typically at depths of 200 to 1,200 meters. The species is often associated with seamounts and underwater ridges, making it a target for deep-sea trawl and longline fisheries. The top alfonsino fishing countries include Japan, Spain, Portugal, and New Zealand, each with established fleets operating in both domestic and international waters. Japan is particularly notable for its consumption and import of alfonsino, known locally as "kinmedai," which is highly valued in sushi and sashimi markets. Spain and Portugal harvest alfonsino in the Northeast Atlantic, especially around the Azores and Madeira, while New Zealand targets this species in the Southwest Pacific. The alfonsino fishery is relatively small compared to other commercial species, but it is economically significant for these countries, and concerns about overfishing have led to increased management and conservation efforts in recent years.
