Understanding recruitment variation (including the collapse) of Saucer Scallop stocks in Western Australia and assessing the feasibility of assisted recovery measures for improved management in a changing environment

This study examined possible contributing environmental factors to the recruitment variability of the Ballot’s saucer scallop Ylistrum balloti across the main stocks in Western Australia. The project was undertaken to explain the variation observed between years and between regions as well...

Establishing baselines and assessing vulnerability of commercially harvested corals across northern Australia

The objectives and outcomes of this project were three-fold. Firstly, we established the abundance and turnover of select, commercially important coral species in areas of concentrated fishing across northern Australia. Improved understanding of the biology and ecology of harvested corals is...

An industry based mark recapture program to provide stock assessment inputs for the Western Rock Lobster Fishery following introduction of quota management

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...

Mitigation measures to reduce entanglements of migrating whales with commercial fishing gear

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...

Fisheries Managers' Workshop

A national fisheries management workshop was held at the South Australian Aquatic Sciences Centre in Adelaide on 26/27 March 2014, which brought together fisheries managers from all Australian jurisdictions. The idea of holding a workshop was promoted by the Australian Fisheries Management...

Need

Whale entanglements are a key performance indicator (KPI) for the WRL fishery in Commonwealth
assessments. Entanglements in 2012 (13 in WRL gear) exceeded this KPI. The KPI breach resulted in
the Commonwealth removing the WRL fishery from the List of Exempt Native Species which is a five
year export approval without conditions and issuing a two year Wildlife Trade Order (WTO) with
conditions and recommendations relating to whale entanglement. This included a condition: "by 31
March 2014, complete a robust evaluation of longer term operational management measures to
reduce the risk of whale entanglements, which could include the removal of some restrictions on
western rock lobsters, spatial and seasonal closures and potential gear modifications". If this condition
isn't met, the WTO may be revoked and therefore the
fishery will not be able to export. The WRL is almost exclusively an export fishery with an estimated
annual GVP of $200 million.
The reason for increased entanglements is a combination of whale population growth (10% p/a) and
an increase in winter fishing resulting from a relaxation of input controls after a move to quota. A
closed season, removing winter fishing would somewhat elevate this issue, although at an economic
cost to the industry as it would no longer be able to attain the high beach prices paid in winter. This
would result in a conservative loss of about $50 million p/a in GVP. Therefore to meet the SEWPaC
conditions, and still allow winter fishing, entanglement mitigation measures are needed.

Objectives

1. Examine the effectiveness of potential gear modifications to the float rigs of fishing pots/traps to reduce their likelihood of entangling whales.
2. Start to collect additional information required to determine the spatial and temporal extent of migrating whales and how this overlaps with commercial fishing gear.

Tactical Research Fund: Decision tree and rapid assessment methodology for new fisheries

The objective of this report is to provide a Rapid Appraisal Methodology process for assessing proposals for new fisheries. If adopted, the methodology could extend to the receipt and assessment of new fishery proposals which may potentially encompass aquaculture, in line with...
