Catch and effort from a specialised recreational pelagic sport fishery off eastern Australia

The common dentex, Dentex dentex (L.), is an iconic marine coastal fish in the Mediterranean Sea. This study was performed in the Bonifacio Strait Natural Reserve (BSNR), (NW Mediterranean Sea). The aims were to: (1) evaluate temporal variation of the artisanal fishing of common dentex (2000-2012); (2) compare and quantify catch rates, fishing techniques and catch composition for artisanal and recreational fisheries, and determine the influence of management measures by both activities; and (3) estimate the production of both artisanal and recreational fisheries. Fishery data were collected from different artisanal fishing surveys (onboard fishing vessels and landings) and recreational fishing surveys (roving). The gears with the highest rates of exploitation were longline (3554 g per 100 hooks) and Trolling (351 g boat À1 h À1 AESE), respectively, for artisanal and recreational fishing. This study showed that catches by both activities were quantitatively higher in partially protected areas than outside them. Production estimations suggest that the recreational fishery contributes significantly to fishing mortality and that it can magnify the negative effects of artisanal fisheries. Specific measures are needed for the sustainable fishery management of common dentex. K E Y W O R D S :fisheries management, IUCN red list, marine reserve, Small-scale fisheries.

“…Our data provide little insight into the mechanisms driving the differences among states, but access to shark meat likely differs; commercial shark fisheries are concentrated near Vic and Tas, where the main markets for shark are based (Patterson, Noriega, Georgeson, Larcombe, & Curtotti, ); shark flesh (aka ‘flake’) may therefore be more accessible and acceptable in these southern states. In NSW, anglers have a broader diversity of recognized gamefish species to target (Zischke, Griffiths, & Tibbetts, ) yielding greater substitutability of mako for other gamefish and potentially decreasing emphasis on harvesting mako sharks (Shelby & Vaske, ; Fisher & Ditton, ; Sutton & Ditton, ; Rogers & Bailleul, ).…”

Motivation and harvesting behaviour of fishers in a specialized fishery targeting a top predator species at risk

Effective management of wildlife resources depends on understanding and cooperating with the human users of the resource, particularly as policies may be rejected if user satisfactions are not met. In Australia, recreational anglers can legally target a migratory top predator, the shortfin mako shark Isurus oxyrinchus, which is also a species at risk. It is assumed that most of the sharks are released and population remains minimally impacted; yet, the actual release rate of this species is unknown and little information is available about anglers that participate in this fishery. Fishing motivations and behaviours were ascertained by a web survey of recreational shark anglers from three south‐eastern Australian states. Respondents reported that ~70% of the captured makos were released, with significant geographic variation in release rates between states. Most anglers reported being motivated by the catch‐based objectives, the thrills and challenges, rather than harvest‐based motivations. However, there were significant differences in harvesting motivation among states. This could be attributed to the varying value assigned to shortfin mako as a sport fish and table fish among regions. Additionally, higher rates of release among anglers from New South Wales may be linked to increased opportunity for resource substitution (i.e. greater diversity of game fish species) and established norms driven by current catch‐and‐release fisheries in that region. Increased participation in catch‐and‐release fishing may be achieved by establishing behavioural norms by the provision of more desirable incentives to release sharks during fishing competitions. Data on regional variation in release rates yield important information for managers to target specialized fishers to incentivize catch‐and‐release fishing with an objective of changing behaviour. Many anglers understand that sharks are important to marine ecosystems and messaging may be important to deliver effective management given that most anglers are motivated by catch‐based objectives even though many enjoy harvesting makos. Information on natural resource user motivations and satisfactions, such as studied here, has the potential to guide management actions and the ways in which managers interact with resource users. A plain language summary is available for this article.

“…Such factors are harder to identify, although annual, seasonal movement of tiger sharks to particular foraging areas has been documented (Lowe et al 1996;Fitzpatrick et al 2012). Indeed, the stronger EAC currents flowing southward during the warmer months mark a seasonal biome shift in this region, which influences the distribution of pelagic fishes such as tunas, kingfish, mackerels and billfishes (Kailola et al 1993;Gillanders et al 2001;Lowry and Murphy 2003;Zischke et al 2012), as well as spawning activity by deep-sea fishes on seamounts (Rowling et al 2010). Offshore movements of tiger sharks in Hawaii have also been linked to patterns in oceanic productivity (Meyer et al 2010).…”
