This report summarises the Sub-Antarctic ling stock (LIN 5&6, excluding LIN 6B) and fishery with spatial structure of the stock, biological parameters, and standardised catch per unit effort (CPUE).

This document describes the operation of rapid updates of New Zealand red rock lobster stock assessments for CRA 1, CRA 2, & CRA 3 done in October 2020. Full stock assessments for each stock are generally done once every 5 years and require significant time and effort. Rapid updates repeat the previous full stock assessment with new data. Rapid updates do not aim to replace full stock assessments but complement them by providing inference about stock status in the years between full assessments.

The purpose of these guidelines is to inform the sustainable development of open ocean finfish farming in New Zealand by providing robust and practical guidance to minimise and mitigate effects on marine mammals. The guidelines focus on mitigation of interactions through site selection, design, and operation of farm infrastructure through carefully designed monitoring programmes to assess the effectiveness of mitigation measures.

Freshwater eel stock assessment requires reliable indices of abundance. A new spatially distributed modelling approach for stream networks was developed using the R package VAST to standardise time series of spatial observations, estimating spatial and temporal variation, habitat associations, and correlations among categories. The new methods generate time series of predictions that are more accurate than previous methods. The models performed well at estimating trends.
