Fishing Methods

Scalefish production and produce expanded with techniques introduced by immigrants from the UK, Scandinavia, Greece and Italy. The diversity and complexity of the modern Marine Scalefish Fishery (MSF) reflects this rich history. A range of traditional production methods were adapted and evolved to suit South Australia’s unique environment and local species.

Today there are 21 different regulated gear types “endorsements” which can be registered to a MSF license which are non-transferable. These endorsements fall into broad categories of; Line (hand line, jigs and longline) Nets (haul, gill and seine), traps / pots (fish, octopus and crab) and rakes (Vongole, dab and crab). The construction and deployment of each entitlement is closely regulated as detailed in the MSF User Guide (2015).

Line Entitlements

Hand Line – All MSF licences are permitted to utilise handlines, where up to three baited hooks or jigs are attached to a line.
Target Species – Used primarily inshore to target King George Whiting, Snapper, Wrasse, and Southern Calamari
Pros – Low maintenance and infrastructure costs
Cons – Limits variety of target species, not efficient for low unit value species.

 HandlineMethodology-Main

Drop Lines – If endorsed on the licence drop lines are made up of a mainline deployed vertically via a weight and float. Hook and bait configuration can be used to target specific species throughout the water column. Typically deployed in deeper reef environments.
Target Species – Snapper, Nannygai and Wrasse.
Pros – Can fish autonomously (set and retrieved) used to target multiple or specific species.
Cons – Passive as opposed to active fishing, Infrastructure and maintenance intensive, can be an entanglement and navigation hazard.
Dropline

Long Lines- If endorsed on the licence longlines are made up of a mainline deployed horizontally via weights and floats. Hook and bait configuration, as well as depth, can be used to target specific species over a distance, typically offshore.
Target Species – Surface longlines targeting Whaler Sharks while Demersal longlines target Snapper with School and Gummy Shark as a bycatch.
Pros – Can be fished autonomously (set and retrieved) low or no bycatch.
Cons – Passive as opposed to active fishing, Infrastructure and maintenance intensive, can be an entanglement and or navigation hazard. An effective method which must be monitored and managed carefully to mitigate localised depletion and resource sharing.

Net Entitlements

Haul Netlink small scale “Purse -seine” method utilises Nylon or Polypropylene net to encircle schooling fish. When retrieved via hand or hydraulics the shrinking circle of net herds the catch toward the pocket. Limited to sheltered water and all State water’s less than 5m.
Target Species – Garfish, Yellowfin Whiting, Australian Herring, Southern Calamari, Snook and Yellow Eye Mullet.
Pros – An efficient method to target a range of herbivorous or low unit value species. The mesh sizes (holes) are regulated to allow undersized fish to escape, furthermore as the catch is free swimming and brailed (dabbed) from the water all undersize or bycatch is released.
Cons – Requires careful monitoring and management to mitigate localised depletion and resource sharing.

NetEntitlement NetEntitlement-2

*Small Mesh Net – * As the name suggests this static net method utilises mono-filament to mesh (ensnare) the fish by the gills. A headline of floats and a foot line of weights holds a wall of net, typically deployed inshore limited to all sheltered and State waters less than 5m.
Target Species – King George Whiting, Yellowfin, Yellow Eye Mullet and Mulloway.
Pros – The mesh size (holes) are designed to target a specific size range of fish, too small and the swim through and two large they bounce off.
Cons – An effective method which requires careful monitoring and management to mitigate localised depletion and resource sharing.

SmallMeshNet SmallMeshNet-2

Large Mesh Net – Large mesh or shark nets made from monofilament are bottom or surface set depending on the target species .
Target Species – Bronze and Dusky Whaler, School and Gummy Shark
Pros – The mesh size (holes) are designed to target a specific size range of fish, too small and the swim through and two large they bounce off.
Cons – Has the potential to be an entanglement risk for large TEP species.

Beach Seine– Commonly constructed of Polypropylene this net is used to encircle schooling fish from the shore. The net is deployed from a small row boat in a large semicircle, once both ends are secured to the shore the net and catch is hauled onto the beach by hand or vehicle.
Target Species – Yellow Eyed and Jumping Mullet, Australian Salmon and Mulloway.
Pros – targeted fishing little bycatch, limited infrastructure, fish can be landed and chilled quickly
Cons – Requires calm conditions and manpower.
