Study Notes
Fishing Gears Overview
- Barricades are non-textile barriers that prevent fish escape, primarily in migration routes.
- Fish corrals use bamboo, brush, or chicken wire to guide fish in tidal waters during migration.
- Fish pots, usually baited, are made from materials like bamboo and rattan to trap fish.
- Fish shelters provide refuge for fish via anchored bundles of twigs, bushes, or weeds.
Hand Lines
- Handlines consist of a line and hooks, including simple and multiple lines.
- Jigger lines have multiple hooks operated by jerking motion under a light.
- Pole and line techniques use a single handline attached to a loop.
- Troll lines are long, baited handlines used in towing operations.
Longlines
- Extremely long lines deployed with several hooks, can be set or drifting.
- Set longlines are anchored and can be submerged or hung on the surface.
- Drift longlines lack fixed attachments, allowing free movement in the water.
Nets
- Impounding nets capture fish by confining them, including set-impounding and filter nets.
- Drift nets and encircling drive-in nets can be driven by noise or other means.
- Traps are passive, guiding fish into chambers with retarding devices to prevent escape.
Hook and Line Methods
- Hooks attract fish using edible or artificial baits, snagging fish as they pass by.
- Types of lines include handlines, pole and lines, jig lines, set long lines, and troll lines.
Grappling and Wounding Gear
- Equipment such as harpoons, spears, clamps, and tongs is used to immobilize fish.
- These methods can wound or kill fish for retention during capture.
Harvesting Machines
- Modern machines mechanically transfer fish from water to vessels.
- Techniques include pumps, hydraulic jets, and conveyor belts for efficient harvesting.
Other Capture Gear
- Various instruments are used, including hand nets, snares, explosives, and electrical methods.
- Snares serve as running nooses; spears and harpoons allow for direct capture.
Barriers and Traps
- Hoop nets feature funnel-like designs with non-return valves.
- Fyke nets utilize multiple entrance funnels for guiding fish.
- Mobile impounding methods involve lift nets and pull or drag nets for active capture.
Seines
- Seines are nets with a bag section bordered by wings, used in both shallow and reef areas.
- Different seine varieties include drag seines, purse seines, and ring nets.
- Blanket nets and bag nets are utilized for capturing fish using light sources or dragging methods.
