This document provides a food safety risk assessment for the proposed use of passive integrated transponder (PIT) tags in a SNA 1 tagging programme. The Ministry for Primary Industries has proposed carrying out a tagging programme to improve the stock assessment for the SNA 1 stock. The last tagging pro-gramme in SNA 1 (which used coded wire tags rather than PIT tags) dates from 1994, and recent trends in biomass have been estimated from catch per unit effort indices.

Blue moki (Latridopsis ciliaris) in MOK 1 and MOK 3 is caught in inshore set-net fisheries while a substantial proportion of the catch from MOK 1 is also taken as a bycatch of inshore trawl fisheries. Most of the catch is taken from the along the central east coast of the North and South Islands encompassing East Cape, Wairarapa, Cook Strait and Kaikoura.

The detection range of passive integrated transponder (PIT) tags potentially suitable for use in a tagging programme for estimating the abundance of snapper (Pagrus auratus) was systematically evaluated. For the tags typically used in fish tagging applications, detection ranges are inherently short – of the order of tens of centimetres. A range of tags was evaluated using a single reader and two different antennas. The reader and antennas were commercial products designed for fish tagging applications.

In New Zealand, captures of seabirds and other protected species are recorded by government observers when they are on-board commercial fishing vessels. This report addresses the question of how many seabirds would be reported caught if every commercial trawl and longline vessel fishing within New Zealand’s Exclusive Economic Zone carried an observer. Statistical models were used to scale up from observed captures, to estimate total captures across all commercial trawl and longline fisheries. Estimates were made for the 2002–03 to 2014–15 fishing years for trawl fisheries, and for the 1998–99 to 2014–15 fishing years for longline fisheries.

The Ministry for Primary Industries (MPI) is developing a risk assessment framework to identify the nature and extent of risks to chondrichthyan populations. This project aims to fill some of the knowledge gaps for some of the high-risk, non-Quota Management System species to reduce the level of uncertainty in the risk assessments of those species, and to provide information on their productivity that can then be used as inputs into future quantitative risk assessments. The species included in this study were seal shark (Dalatias licha), Owston’s dogfish (Centroscymnus owstonii), longnose velvet dogfish (Centroselachus crepidater), and Plunket’s shark (Scymnodon plunketi). Specimens and data were collected aboard commercial fishing vessels and research vessels, and integrated with existing data and specimens held by NIWA.

The primary purpose of this 2017 study was to repeat the 2008 benchmark study that explored urban and rural New Zealanders’ views of rural New Zealand and the primary sector.
This document summarises MPI's achievements over the 2016/17 year and describes our performance in striving to reach our outcomes.

Age and growth were estimated for carpet shark, common electric ray and blind electric ray from growth increments on their vertebrae and eye lenses. All three species grow moderately fast, and longevity is low to moderate compared with other elasmobranchs. Length and age at maturity, length at birth/hatching, and litter size were estimated. The length of the gestation period, and whether females have a resting period between pregnancies, are poorly known.

Historical information indicates an increasing range of fish and invertebrates were exploited in these regions once commercial fisheries were established in the 1860s. Noticeable declines in abundance of easily exploited species occurred in the late 19th and early 20th centuries prior to the collection of fishery statistics. Until 1935, action to conserve fisheries was greatly impeded by a lack of consistently collected landings data. Similar studies of other regions would be beneficial.

The bottom-contacting deepwater Tier 1 and Tier 2 target fishstock footprint for 1990–2016 was estimated at 335 812 km2. This represents 8.2% of the Territorial Sea and EEZ seafloor area and 24% of the seafloor open to fishing, down to 1600 m. Tier 1 fisheries accounted for 93%, with hoki effort contributing 50%. The 2016 footprint covered 44 261 km2, 76 km2 of which was not contacted during 1990–2015. The aggregated swept area was 3.07 million km2 for 1990–2016 and 78 372 km2 for 2016.

This report documents the preparation of data on observed protected species captures in New Zealand fisheries during the period between 2002–03 and 2014–15. Recorded captures included captures of seabirds, marine mammals, and turtles. The observer records were linked to fishing effort data, and corrections to capture records and species identifications were made, prompted by expert reviews through necropsies and photograph examinations.
