This collaborative project between industry and academia was developed in response to the need for a reliable and simple measurement of fish health status in farmed populations as well as in a research context, to assess the outcomes of trials on health, nutrition and environment. We have developed...

The West Coast Lobster Managed Fishery (WCRLMF) moved from input to output controls in 2010. This change directly affected the relativity of a number of fisherybased data sources, making assessment of the fishery more problematic. A novel examination of the stock dynamics was required to help ensure...

This project provided a robust assessment that gear modifications introduced into the WCRLMF
and octopus fisheries have reduced the number of reported entanglements. The management
arrangements around the implementation of these modifications are appropriate in light on the
new spatial and temporal...
