Scampi is a worst choice seafood. An alternative seafood choice is rock lobster (crayfish). The best rock lobster comes from the east coasts of the North and South Islands, between Gisborne and Kaikoura.
This is the largest prawn-like species found in New Zealand waters, although it is actually a small lobster. It is found all around New Zealand at depths of 200 to 750m. The commercial fishery is under the quota management system after some controversy over allocation of quota. It is caught using specialised deepwater bottom trawls, with fine mesh nets.
Scampi are caught with a fine mesh trawl. The fishing method has a high level of bycatch of fish, invertebrates, marine mammals and seabirds (over 200 a year). There is also considerable destruction to seabed habitats, species and associated marine life. Also of concern is the unknown sustainability of recent catch levels and limits in all of the larger quota management areas, the uncertainty about stock boundaries, and the absence of a management plan. There is a high level of fish bycatch caught in scampi trawls (up to five times the target catch), including ling, hoki, sea perch, and red cod.

Export value of $17.8 million in 2009.
Regional differences between scampi caught at the Auckland Islands versus the rest of New Zealand were assessed, however there was no difference in scores: both ranked red, are worst choice seafood and should be avoided.
|Score:||Both longline and trawl – D|
|Population size:||Unknown for many areas. Likely to be above 40%Bo for SCI1, SCI2 and SCI3.|
|Annual catch limit:||Total catch limit of 1224 tonnes was increased to 1244 tonnes from 1 October 2016.|
|Recorded catch:||Reported landings of 879 tonnes in 2014-15.|
|Stock trends:||Variable catch rates in many stocks.|
|MSY Status:||Unknown for most stocks. Likely to be above 40%Bo for SCI1, SCI2 and SCI3.|
|The Ministry of Primary Industries assessment plenary report includes:||
“Assessments have been conducted for areas considered to be the core regions of SCI 1, SCI 2 and SCI 3 (accounting for over 96.5% of scampi landings in each fishery).”
SCI 1 (Bay of Plenty/Northland): “Very Likely to be at or above target (40%Bo). Overfishing is Very Unlikely to be occurring.” “Historical Stock Status Trajectory and Current Status. Spawning stock biomass increased to a peak in about 1995, declined to the early 2000s, and has remained relatively stable since this time. The stock is predicted to remain above 40% Bo up to 2021 under current catches and TACC.”
SCI 2 (East Coast North Island): “Very Likely to be at or above target (40%Bo). Overfishing is Exceptionally Unlikely to be occurring. Biomass increased during the early 1990s, but declined steadily after this until the early 2000s. Biomass increased steadily between 2008 and 2014, declining slightly since then.”
SCI 3 (Chatham Rise): “B2014 was estimated to be 54% (photo excluded), or 60% (trawl excluded) B0. Very Likely to be at or above the target. Overfishing is Very Unlikely (< 10%) to be occurring. The stock is predicted to remain above 40% B0 up to 2020 under current catches and TACC. Projected stock status under TACC catches for the trawl excluded model is 70% B0. Projected stock status under TACC catches for the photo excluded model is 42% B0.”
6A (Auckland Islands): No accepted assessments. There are no other yield estimates.
|Distribution:||Scampi are widely distributed around New Zealand at depths of 200-750m on the continental slope.|
|Maximum age (years):||15 (approx)|
|Age at sexual maturity:||3-4|
|Reproductive output:||Low to moderate (females carry only a few tens to a very few hundred eggs).|
|Ability to recover:||Moderate|
|Fishing method(s):||Bottom trawling with fine mesh gear.|
|Habitat damage:||Trawling for scampi has significant adverse impacts on seafloor habitats as it scrapes the seabed, impacting a range of non-target species. In the Bay of Plenty, over 1,100 km2 is swept by trawlers each year, which is one of the smaller scampi fisheries (Cryer et al, 2002).|
|Habitat of particular significance:||Impacts include habitat modification, loss of biodiversity, loss of benthic productivity and modification of important breeding and juvenile fish habitat.|
|Bycatch:||There is a high level of non-threatened species bycatch caught in scampi trawls (up to five times the target catch), including ling, hoki, sea perch, red cod, silver warehou and giant stargazer. Discards are dominated by rattails, javelinfish, skates and crabs, ling, red cod, hoki, spiny dogfish and sea perch. A wide range of benthic invertebrate species are also taken as bycatch.|
|Ecological effects:||Scampi trawling causes significant disruption to seabed species assemblages, reduces deepwater biodiversity and modifies the structure of marine communities.|
|Bycatch:||The average seabird capture rate in scampi trawl fisheries over the last ten years (all areas combined) is about 5.57 birds per 100 tows, a moderate rate relative to trawl fisheries for squid (13.79 birds per 100 tows). Captures include globally threatened black-browed, Salvin’s and white-capped (shy) albatrosses, plus sooty and flesh-footed shearwaters. Around the Auckland Islands, threatened New Zealand sea lions are also caught.|
|Management component:||Single species but stock structure is not well understood.|
|Quota Management Species:||Introduced on 1 October in 2004.|
|Management plan:||Deepwater management plan for 2010-15 is out of date, and has yet to be reviewed and replaced. Scampi is not part of the current plan. There is no operational plan and the old Deepwater plan lacks key environmental standards. The National Plans of Action on Seabirds and Sharks are more relevant to bycatch issues but they are slow to be implemented.|
|Stock assessment:||Quantitative assessments accepted for SCI 1, 2 and SCI3. Assessments have yet to be accepted for SCI 6A. No completed quantitative assessment for other areas.|
|Research:||Research is focused on stock assessment.|
|Observer coverage:||8.32% coverage over the last 5 years but it is unlikely to be spatially or temporally representative of the fishing effort.|
