Trumpeter is a worst choice fish. An alternative is trevally caught by purse seine, or terakihi from the west coast of the South Island.
Trumpeter occurs in the cool, temperate waters of the southern hemisphere, from the Indian Ocean to South America. In New Zealand it is found from the Bay of Plenty southwards to the Auckland Islands, but is mainly caught on the east coast of both islands. There is little targeted fishing for trumpeter: it is mainly caught as a bycatch in line fisheries, with some caught in trawl and set nets.
Trumpeter are mainly caught by longlines. Concerns about the fishery include the absence of basic biological information about trumpeter, the lack of a quantitative stock assessment and the unknown sustainability of recent catch levels. Also, the uncertainty over stock boundaries and the potential for localised depletion of some populations, plus the lack of a management plan. As a bycatch species itself, trumpeter fishing is also associated with other non-target fish bycatch. There is also the seabird bycatch associated with inshore longline fisheries.
Not certified under any scheme.
There are no published exports. Trumpeter is sold in New Zealand.
No regional or fishing method difference.
|Annual catch limit:||Limit set at 144 tonnes since 2001-02.|
|Recorded catch:||Estimated landings of 56 tonnes in 2015, the lowest catch in over 10 years.|
|Stock trends:||Unknown. There is a risk for localised population to be quickly fished out.|
|The Ministry of Primary Industries assessment plenary report includes:||“No estimates of current and reference biomass are available. It is not known if recent catch levels are sustainable.” (MPI 2016, p 1535).|
|Distribution:||Occurs from the Bay of Plenty southwards to the Auckland Islands, but is seldom common.|
|Maximum age (years):||43+|
|Age at sexual maturity:||Unknown|
|Growth rate:||Likely to be moderate|
|Ability to recover:||Moderate|
|Fishing method(s):||Mostly caught as bycatch in coastal bottom line-fisheries, with some caught in trawl nets and set nets.|
|Habitat damage:||Low given longline fishery, but trumpeter are restricted to rocky reefs|
|Habitat of particular significance:|
|Bycatch:||Various fish species are caught as bycatch, in fisheries where trumpeter is also caught.|
|Bycatch:||Inshore bottom longline fishery is estimated to catch 337 seabirds annually.|
|Management component:||Single species, but the nature of stocks is uncertain. The scope of how the southern hemisphere population and localised populations fit is unclear.|
|Quota Management Species:||Yes, since 1998.|
|Management plan:||There is no approved inshore plan.|
|Stock assessment:||No quantitative stock assessment.|
|Research:||There has been no focused research on trumpeter this century.|
|Observer coverage:||Unobserved in targeted fishery.|
