This report describes the results of blue cod (Parapercis colias) fixed- and random-site potting surveys carried out concurrently in Marlborough Sounds in September/October 2017. Estimates are provided for population abundance, size and age structure, sex ratio, total mortality (Z), and spawner-per-recruit ratio. This is the eighth survey in the fixed-site survey time series that began in 1995, and the second full random-site survey.
Risk Profile: Vibrio vulnificus in bivalve molluscan shellfish
The purpose of this Risk Profile is to critically review available information and determine if the risk to human health from V. parahaemolyticus had changed since 2003.
Keywords: Risk Profile, Vibrio, parahaemolyticus, bivalve, molluscan, shellfish
Annual Review Report for Deepwater Fisheries 2016/17
A panel of independent reviewers assessed the current state of MPI in late 2012, and considered how well it is placed to deal with the opportunities and challenges faced over the medium-term. The reviewers noted 4 'future state' enhancements - managing and developing MPI’s people, delivering on our export goal, MPI’s leadership role, and systems management. The review was managed by the State Services Commission.

Farmed animals in New Zealand contribute around 46% of the country’s greenhouse gas output. Of this, approximately 69% is methane (CH4) and 31% is nitrous oxide (N2O), with 80% of the latter resulting from nitrification and denitrification of urinary nitrogen by soil microorganisms and, to a much lesser extent, faecal nitrogen. To date, models evaluating the nitrogen (N) excretion of ruminants have assumed that N excreted in urine is constant and research on mitigating N2O output has largely focussed on nitrification inhibitors such as dicyandiamide (DCD), stand-off pads to keep stock off pastures in wet conditions and feeding low N feeds such as maize silage.
Framework for assessment of climate impacts on New Zealand's Hydrological Systems

The objective of this research was to develop a ceonceptual framework for the assessment of the effects of climate chagne on hudrological systems in New Zealand. This research commenced with a literature review emphasizing the types of impacts that have been detected previously and methods for detecting and modelling impacts. The conceptual framework was developed and then applied to the Waimea Pains as a test catchment to assess the effect of climate change. Existing climage and hydrological data were analysed to assess possible climate effects. Hydrological and socioeconomic models were developed and implemented to relate possible climate change to derived changes in water availability and economic productivity within the test catchment
