Herring-like fish

There are two families in the order Clupeiformes; the herring family (Clupidae) and the anchovy family (Engraulidae) and are relatively small, silver-coloured fish. They swim in large, pelagic schools and feed on plankton. They are occasionally found near the shore, however they usually swim further out in the open sea at depths up to 200 m. Most species are capable of producing a lot of eggs each spawning event, up to 200.000 per adult female. A large share of the global wild catch consists of haring-like fish. Not everything is used for direct human consumption, a large share is processed as fish meal or fish oil that form the essential ingredient for fish feed in aquaculture. Haring-like fish swim in large schools which makes them susceptible to large scale (industrial) fishing.

Alfonsino

Alfonsino is also known as red bream, longfinned beryx, alfonsin and emperor. Alfonsino is a schooling species. Schools mainly occur around rocky bottoms at depths of 25 to 1300 meters. Alfonsino occurs along the coasts of Europe and Africa and around islands in the Indian and Atlantic Ocean.

Final assessment

Explanation assessment

The deep sea fishery on alfonsino (sometimes sold as red bream) is a small scale fishery, with a limited amount of data available. There is not enough data available for a stock assessment. This species is very vulnerable to fishing pressure. For that reason, it scores red for the category fish stock and fishing pressure.

Fishing with [hand-operated] lines has little bycatchBycatch:
Species caught next to species targeted for fishery. By-catches can consist of non-commercial species and species that are too small, and can be kept (this part is sometimes called by-product) or thrown back into the sea (discards). of vulnerable species, such as rays and sharks. This fishery is unlikely to have a a negative impact on the ecosystem. It receives an orange score for the category ecosystem effects.

The Azores has a very strict fishery law. Harmful fishing techniques are forbidden, there is a minimum landing size and protected areas are closed for fishing. This fishery receives a green score for the category management.

The final assessment for this fishery is orange. This fish is a good alternative for species with a red score, but it’s not the best option.

Fish in season

Fish is in season when the spawning period has ended, as the quality is then at its best.
