The Ministry for Primary Industries (MPI) has funded intertidal shellfish surveys in northern New Zealand since 1992. These surveys monitor the cockle and pipi populations to find out where these shellfish are and how many are there. current 22 October 2014
This Regulatory Impact Statement provides an analysis of whether current legislative and regulatory requirements on Livestock Improvement Corporation (LIC), a commercial entity, should be removed, and whether the historical copy of the core database, and future core data LIC collects, should be subject to oversight by the Access Panel. current 22 October 2014
This document summarises the Ministry's achievements over the 2013/14 year and describes our performance in striving to reach our outcomes. current 20 October 2014
Estimates of relative species proportions and catch-at-age for the three jack mackerel (Trachurus) species in the commercial JMA 7 catch for 2012–13 are presented. The available time series of catch-at-age estimates, sex ratios and species proportions for the JMA 7 catch (2006–07 to 2012–13) are summarised. current 20 October 2014
Age compositions of orange roughy were estimated from three spawning plumes (Main Plume, Rekohu Plume, and Mount Muck) on the northeast Chatham Rise (ORH 3B) sampled in 2013, from a 1994 wide area research survey on the northwest Chatham Rise (ORH 3B), and from three research surveys on the Challenger Plateau (ORH 7A) in 1987, 2006 and 2009. The distributions were produced for use in assessments of these stocks. current 20 October 2014
This report documents a further two years of recreational catch sampling from KAH 1, which took place during the first 4 months of 2011 and 2012. Trends in length and age distributions from East Northland, the Hauraki Gulf and the Bay of Plenty are broadly consistent with those seen in the existing 8 year time series lasting from 2001 to 2008. A time series of total mortality estimates suggests that overall rates of mortality have declined in recent years and are at acceptable levels. current 20 October 2014
Kaitiaki in the Te Tai Hauāuru Regional Fisheries Forum and Tauranga Moana Iwi Customary Fisheries Trust play a significant role in assisting Marae with the provision of kaimoana (shellfish and finfish) for customary events held on Marae and other venues for whānau, hapū and Iwi. This Report identifies kaimoana species that are cultural significant to Iwi, how the current process is working for Marae and the main issues with gathering customary harvest data and working with Iwi. current 20 October 2014
This booklet lists the food additives approved by the Food Standards Code for use in food. Additives can improve the keeping quality of a food by making it last longer on the shelf or in the fridge (for example, a preservative to prevent the growth of bacteria or a humectant to stop food from drying out), or improve the taste or appearance of a food (for example by the use of flavours, thickeners and colours). current 16 October 2014
Seagrass (Zostera muelleri) areas were sampled for invertebrate/fish assemblages. Northern subtidal meadows were important fish nurseries, especially for snapper and trevally. Influence on invertebrate communities was complex and spatially variable; presence did not always equate to higher invertebrate abundance, richness or secondary production. Significant genetic differentiation indicated limited regional gene flow. A framework is provided to aid ranking seagrass meadows ecological values. current 15 October 2014
A 2013 workshop Future proofing New Zealand’s shellfish aquaculture: Monitoring and adaptation to ocean acidification, brought together experts from government, the aquaculture industry and science organizations from the US and NZ to raise awareness of ocean acidification within the NZ aquaculture community, identify ways to protect the aquaculture industry and develop US-NZ scientific cooperation to address OA. Papers presented at the workshop and points raised during discussion are summarised. current 13 October 2014
