Shark Futures: Sustainable management of the NSW whaler shark fishery

New South Wales Department of Primary Industries (NSW DPI) presents new information exploring the shark catch of the NSW Ocean Trap & Line Fishery and developing methods to ensure an accurately reported, sustainable and profitable fishery for large sharks is maintained. A combination of...

Byproduct: Catch, economics and co-occurrence in Australias longline fisheries

The longline sector of the Eastern Tuna and Billfish Fishery (ETBF) and the Southern and Western Tuna and Billfish Fishery (SWTBF) target four main species and incidentally take over 80 other species as “bycatch”. Significant amounts of these species are often retained for sale, and...

Need

Following many expressions of public concern regarding the potential for finfish/tuna aquaculture to attract sharks to coastal areas, at both regional development and individual site applications, PIRSA Fisheries and Aquaculture identified the need for an understanding of the factors that may explain associations between sharks and finfish/tuna aquaculture activities. This view was reinforced at meetings of the AAC (including a presentation from the PI on 22 Feb 2013), who are a legislated body under the Aquaculture Act 2001, advising the State Minister for Agriculture, Food and Fisheries on matters relating to aquaculture development. As a consequence, this project was listed as a priority area for investment by the SAFRAB.

A previous FRDC funded workshop (2002/040) identified a need to understand factors that may explain interactions between pelagic sharks and aquaculture activities. Some of the findings highlighted during this workshop are now considered to be outdated. For example, anecdotal accounts from finfish farmers and commercial fishers suggest that white sharks sightings have increased in the past decade in Spencer Gulf and this may have implications for the frequency of interactions with the fishing and aquaculture industry. The provision of data to further inform the public’s current perception of the aquaculture industry represents a key priority in South Australia’s Fisheries and Aquaculture R&D Strategy. During the development of this project the need for this research was discussed with key industry representatives.
This proposal addresses key objectives of the Draft White Shark Recovery Plan, 2010 (2c, 7a, 9a and 9b).

Objectives

1. Determine if activities associated with finfish aquaculture correlate with spatial and temporal residency and migration patterns of pelagic sharks.
2. Assess and compare patterns of residency of pelagic sharks in ‘natural’ foraging areas, and any overlaps with community activities.
3. Develop a Code of Practice for removal and release of pelagic sharks from finfish aquaculture cages.

Summary

The report focuses on the movement dynamics of two pelagic sharks, the White Shark (Carcharadon carcharias) and Bronze Whaler (Carcharinhus brachyurus), in South Australia. Specific aims were to: (1) determine if aquaculture activities correlated with patterns on fidelity and migration; and (2) assess and compare the use of natural foraging areas and areas used during human marine activities. Additional objectives included the development of: industry guidelines for removal and release of pelagic sharks from finfish aquaculture pontoons, and surveys to collect baseline information on perceptions of shark associations with aquaculture and other marine activities. 
Key outcomes of the project include provision of advice to marine policy-makers regarding overlaps between sharks, marine industries and areas used during community activities (including marine parks). This project addressed important research and management questions that existed for over a decade.

Shark and other chondrichthyan byproduct and bycatch estimation in the SEF Trawl and non-trawl Sectors

The project met all four objectives completely and the outputs from the project are important inputs for the management of byproduct and bycatch. Data from the Integrated Scientific Monitoring Program (ISMP) and from fisher logbooks were analysed for the South Eastern Trawl Fishery (SETF) during...
