Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
General
Saloptia powelli is found on rocky substrates in deep water. Nothing is known or published on its biology.

Fisheries-dependent
Saloptia powelli is captured by dropline fishing in 100 to 200 m depth in Pacific Island countries (Dalzell and Preston 1992). It is an important component of the deep water handline fishery in the Marianas (Polovina and Ralston 1987).

Justification
There is insufficient data on population trends to assess the population or fisheries status of this species and it is, therefore, assessed as Data Deficient.

Population

Population
General
No current information on population trends or abundance for Saloptia powelli.

Fisheries-dependent data
Saloptia powelli was considered a virgin stock in the 1970s to 1980s (Dalzell and Preston 1992). It is taken in deep water drop line and handline fisheries throughout most of the Pacific; in the Cook Islands this species dominated the grouper catch (Polovina and Ralston 1987, Dalzell and Preston 1992). It is likely to be taken in any deep water fisheries within its range and is specifically is targeted in Japan.

Threats

Major Threats
The greatest threat to Saloptia powelli is overfishing. It is not protected through any conservation measures (beyond the depth range of many marine protected areas), therefore research is recommended to assess this interesting monotypic species.
