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...

Underwater measurement of trawl gear in operation

The objective of this report was to measure trawling gear with the Trawl Instrumentation System (TIS). The method was similar to that described in Cruise Report no. 76. Each net and door combination was towed at various log speeds, and was maintained at each log speed for about 20 minutes while...

Need

Whale entanglement in fishing gear has posed a major threat to the Western Rock Lobster (WRL) industry over the last decade. Adverse media attention has to date been avoided, but 2020 saw the first entangled whale appear dead on a WA beach entangled with gear from the state's fisheries. Similarly, several "public" rescues were undertaken of entangled whales which is extremely dangerous. Attempts to disentangle whales has led to the death of responders previously in both Canada and New Zealand. Such events have the capacity to provide a significant threat to the activities of the WRL industry through erosion of their social license.
A program to direct entanglement mitigation research over the next four years will increase the strategic focus of research and increase the efficiency of the application and granting process, thus leading to a more rapid implementation of outcomes into the management of the fishery. Critically, broad dissemination of the outcomes of these project will assist in creating a more resilient social license. This will be important when adverse media attention is focused on the industry as the result of either the death of a whale or responder attempting to disentangle the whale.

Objectives

1. Understand the inter-annual shifts in the humpback whale migration along the WA coast
2. Determine the dynamics and WRL gear involved in humpback whale entanglements
3. Determine the population size of the Western Australian (Stock D) humpback whale population.
4. Investigate novel mitigation measures to minimise entanglements in WRL gear.
5. Support WRL gear disentanglement operators through provision of equipment and new technologies.

Gear interaction of non-targeted species in the Lakes and Coorong commercial and recreational fisheries of South Australia

This project was developed by SARDI, in consultation with PIRSA, Lakes and Coorong Fishery (LCF) licence holders and relevant stakeholders, over several years. Proposals to investigate interactions with non-target species and discarding from the LCF in the Murray River estuary and Coorong...
