Title: FAR 2017/06 Estimating the abundance of scampi in SCI 6A (Auckland Islands) in 2016.
FAR-2017-06-Scampi-SCI-6A.pdf (1.3 MB)
Photographic and trawl surveys of scampi in SCI 6A were conducted in February/March 2016. The photographic survey estimates of scampi and burrows both showed an increase on the 2013 estimate. The trawl survey estimate reflects a marked reduction from 2013, but an enforced vessel change raised questions over comparability with the previous series. Almost 3900 scampi were tagged and released to investigate growth and some animals have been recaptured by industry.

FAR-2016-55-SCI3-characterisation-and-assessment.pdf (18.5 MB)
A fishery characterisation and stock assessment have been undertaken and accepted for SCI 3. A three stock model was developed, based on previous studies. Models excluding trawl or photo surveys were examined. Both approaches suggest SSB is currently around 54–60% SSB0. Models excluding trawl surveys suggest stock status would improve to 70% SSB0 by 2020 with future catches at the TACC, while models excluding the photo survey stock status would decline to 42% SSB0

FAR- 2016-51-Characterisation and length-based population model for scampi (Metanephrops challengeri) in the Bay of Plenty (SCI 1) and Hawke Bay–Wairarapa (SCI 2).pdf (19.3 MB)
Assessments of SCI 1 and SCI 2 stocks have been updated, and both were accepted. For SCI 1, SSB remains stable at around 75% SSB0. Fishing intensity has consistently been below F 40% B0. For SCI 2, SSB has continued to increase, and is between 89% and 113% SSB0. Fishing intensity peaked in 2002 but has declined in recent years, while SSB/SSB0 has increased. For both stocks, future catches up to 156 tonnes (SCI 1) or 200 tonnes (SCI 2) to 2021 are not predicted to reduce the SSB below 40% SSB0.

FAR-2016-30-Access-point-survey-Western-Bay-of-Plenty (1).pdf (2.5 MB)
The amateur harvest of rock lobster, scallop, kahawai and red gurnard was estimated using creel surveys at boat access points in the 2010–11 and 2011–12 fishing years. The survey area was from Port Charles, Coromandel to Maketu, central Bay of Plenty. Over 25 000 boats were intercepted using a mix of stationary and roving creel surveys. The results were expanded to estimate harvest for whole QMAs and all methods using data from the 2011–12 National Panel Survey.

FAR-2016-17-Scampi-2015.pdf (1.1 MB)
Photographic and trawl surveys of scampi in SCI 1 and 2 were conducted in February/March 2015. For SCI 1 both surveys suggest that population biomass and abundance has remained relatively stable since the early 2000s. For SCI 2 both surveys suggest that population biomass and abundance has increased since 2006. About 5600 scampi were tagged and released to investigate growth, and recaptures to date have been low. Scampi emergence patterns were investigated with acoustic tags.

The amateur harvest of rock lobster and scallops was estimated using creel surveys from 1 December 2007 to 28 February 2008. All the main access points were covered on the Coromandel Coast from Cape Colville to Hot Water Beach on 16 survey days. The total estimated harvest for the three months was 2.8 t meat weight of scallops and 7.3 t green weight of rock lobster. Potential improvements to the survey method for these species and how larger areas could be covered are discussed.

FAR_2014_48_2777_Scallop-Management-Strategy-Evaluation.pdf (1.1 MB)
This report describes a management strategy evaluation for Coromandel scallop. Two approaches for managing the fishery were investigated; one with a low base TACC which can be increased in-season based on the results of a resource survey, and the other with higher base TACCs and closure of individual scallop beds when CPUE drops below specified thresholds. Decision rules were evaluated against the Harvest Strategy Standard reference points, as well as measures of average and variability of catch.

A dive survey of Pecten novaezelandiae was conducted in the Te Whaka ā Te Wera Mātaitai, Stewart Island, to provide information on size-frequency and density of scallops. A total of 383 live scallops were sampled over 20 sites of 100 m2 each. Very low densites were observed and most scallops within the Mātaitai were found at two sites. Size frequency distribution shows the presence of large scallops in the Mātaitai. Uneven distribution of scallop size frequency suggests inconsistent recruitment

 Scampi (Metanephrops challengeri) form burrows in the seabed, and photographic surveys counting burrows are used to estimate stock abundance. Other species also form burrows, and this report reviews available data from the Chatham Rise to identify potential burrow formers, and evaluate whether these burrows were likely to be confused with those of scampi. None of the species recorded of appropriate size to be confused with scampi are actually known to generate burrows.

FAR 2013 18 Biomass survey and yield calculation for the Coromandel commercial scallop fishery.pdf (1.1 MB)
This report summarises research and fishery information for scallops (Pecten novaezelandiae) in the Coromandel scallop stock (SCA CS). A dredge survey of the main commercial scallop beds and adjacent areas was conducted in April–May 2012 to estimate the population abundance, biomass and size structure of scallops. Estimates of Current Annual Yield were calculated for the 2012–13 fishing year, by applying a reference rate of fishing mortality (F0.1) to the estimated start-of-season recruited meatweight biomass of scallops.

AEBR_100.pdf (6.5 MB)
This report presents estimates of annual bycatch and discard levels in the commercial scampi fishery based on reported effort and scientific observer data. Combined estimates were made for QMS species, non-QMS species, invertebrates, and rattails; separate estimates were made for javelinfish. Scampi accounted for about 17% of the total catch; rattails (29%), sea perch (8%), ling (7%), and hoki (6%) were the main bycatch species. Currently about of 4.2 kg of fish are discarded for every 1 kg of scampi caught.

Title: Abundance of scallops (Pecten novaezelandiae) in Coromandel recreational fishing areas, 2009 and 2010.
12_24_FAR.pdf (803.0 kb)
Diver surveys of scallops were conducted in 2009 and 2010 at selected recreational fishing areas in the Coromandel stock (SCA CS), marking the fourth and fifth in a 2006–10 series of annual surveys of these areas. The abundance and size structure of scallops varied markedly among areas. Scallop densities in areas open and closed to commercial dredging were compared using data from the 2006–10 diver and dredge surveys. Abundance in commercial and some recreational areas seems to have varied in similar ways but it is difficult to draw firm conclusions about the nature of this relationship.

Photographic and trawl surveys of scampi in SCI 3 were conducted in September/October 2013. Estimates of burrows have increased steadily since 2009, with estimates of scampi showing a smaller relative increase. Trawl catch rates were comparable with 2010, and higher than 2009. Over 3300 scampi were tagged and released to investigate growth, and recaptures to date have been low. Scampi emergence patterns were investigated with acoustic tags.

Title: Burrowing megafauna in SCI 3.
FAR_2013_20_2530_SEA2011-13, Obj.1, RR1.pdf (706.2 kb)
 Scampi (Metanephrops challengeri) form burrows in the seabed, and photographic surveys counting burrows are used to estimate stock abundance. Other species also form burrows, and this report reviews available data from the Chatham Rise to identify potential burrow formers, and evaluate whether these burrows were likely to be confused with those of scampi. None of the species recorded of appropriate size to be confused with scampi are actually known to generate burrows.
