Life span: Up to about 23 years.

Habitat: Alfonsino are a deepwater species that generally live near the seafloor. Alfonsino are usually found at depths of 200‑400 metres, although they are known to occur down to 1300 metres. Alfonsino tend to aggregate on seamounts. Aggregations are usually associated with rocky/sandy substrates. Juveniles are pelagic.

Prey: Fish, crustaceans and cephalopods.

Predators: Larger bony fish and sharks.

Reproduction: Alfonsino reach reproductive maturity at 5‑8 years old. Spawning occurs during the summer. Females are serial spawners and release eggs 10‑12 times at intervals of about four days during the spawning season. Females produce 270 000‑675 000 eggs per spawning event. Eggs hatch after about 8 days.

Management of catch

The Commonwealth catch of Alfonsino around the south east of Australia is managed by quota. Which means the catch of this fish by commercial fishers is restricted by weight.

Commercial fishermen are required to fill in records of their catches, during each fishing trip and when they land their catch in a port. This helps us keep records of how much is being caught.

AFMA decide on the amount that can be caught each year from expert advice and recommendations from fisheries managers, industry members, scientist and researchers.

Alfonsino can also be caught in the High Seas area. Australian boats fishing for Alfonsino in this area are limited in much they can catch and where they can fish. They must have a High Seas permit authorised by AFMA.

Area caught

Alfonsino is a deepwater fish that is known to move further from the bottom at night. It is often found over seamounts and underwater ridges.

The majority of Alfonsino caught by Australian boats are caught in the High Seas and the East Coast Deepwater Zone.

Fishing gear and environmental impacts

Midwater trawl gear has low impact on habitat because the gear rarely comes in contact with the seabed.

On the High Seas, fishers are restricted to areas that have been fished before. Also, if evidence of vulnerable corals and sponges are found,  they must stop fishing and  move bottom fishing activities 5 nm away from the area.
