Targeted species: Flatfish, swordfish, tunas and whales]]> 2022-02-08 05:48:15 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034726819 200084561 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034729287 They are netting bags that are towed through the water to catch targeted species lurking in the area. The trawl entrance should remain open at all times so fishes can enter into the trawls.

Targeted species: Scallops, clams, mussels, cod, haddock, hake, sandeel, flatfish, weakfish, croakers, shrimps,  herring, mackerel, horse-mackerel, blue whiting and pollock]]> 2022-02-08 05:50:20 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034729287 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034731025 2022-02-08 05:51:49 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034731025 200084561 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034732457 Can be described as a combination of trawling and seining. When the seine and warps sank to the bottom, the warps are hauled. While tightening, the warps move inwards towards the centre line between the vessel and the seine bag. targeted species in the encircled area will then be herded towards the central part of the area. As the warps are further tightened, the seine bag moves forward and catches the targeted species.

Targeted species: Different flatfishes like plaice and sole, cod, and other demersal species]]> 2022-02-08 05:53:01 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034732457 200084561 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034737132 2022-02-08 05:57:14 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034737132 200084561 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034737482 2022-02-08 05:57:35 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034737482 200084561 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034741694 Advantages: Highly selective, does not cause bycatch or pollution, capture larger fishes
Disadvantages: Can target wrong targeted species when the spear is thrown, person is at risk of drowning or attacked by species like sharks when throwing spears]]> 2022-02-08 06:01:45 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034741694 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034742625 2022-02-08 06:02:41 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034742625 200084561 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034744084 - The catch quality drastically becomes lower as the spears/harpoons pierced through the flesh of the animal
- Some harpoons contain poison so when the harpoon strikes the animal, the body would become poisoned and the meat would have high traces of poison that cannot be eated]]> 2022-02-08 06:04:12 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034744084 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034745139 Made of fine threads and stationed with floats(pelagic) or weights(bottom). 
It catches fish by gilling, meaning the fine is caught in the net by the Gill region. This occurs when the fish encounter the nets while feeding or migrating, and catches are more successful with low visibility(low light or high turbidity). 

Targeted species: pelagic, like tuna, mackerel, salmon, squid, herring and demersal, like cod, flatfish, snapper and croakers]]> 2022-02-08 06:05:14 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034745139 200084561 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034745395 2022-02-08 06:05:32 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034745395 200084561 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034746313 - Reduction in populations of targeted fishes
- Habitat disturbance
- Food chain imbalances]]> 2022-02-08 06:06:21 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034746313 200036753 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034747496 Use of long lines with hooks placed at regular intervals. Baits/artificial lures are attached to the hooks to attract fish by exploiting the chemical sense of the fish. 

Longlines can be both pelagic & benthic, depending on target species.

Advantage:
Low sea-bed destruction
small fish less likely to get caught due to size of bait & hooks
Massive yield
less energy consumption
Disadvantage:
High chance bycatch (can be mitigated by adjusting equipment eg. hook size)

Catch quailty: Good quality as less compression and less blood loss and quicker harvest.
Environmental impact: Bycatches of unwanted targets, can be mitigated by adjusting gear used]]> 2022-02-08 06:07:34 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034747496 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034751339 2022-02-08 06:11:09 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034751339 200084561 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034752212 Advantages: Fishes swimming down are unable to escape the net, does not cause sedimentation of seabeds
Disadvantages: High chance of having bycatch, induce more pressure in on fish stocks

Made of 3 nets, a middle panel with small meshes and 2 outer side panels with larger meshes
When a fish comes in contact with the net, it will press the small mesh net through the large mesh net, causing it to be entangled or pouched

Gear can have multiple hooks. Line is attached to a boat either moving or stationary or from shore. 

Target species: Pelagic & demersal fish

Advantage:
Easy and simple to use
Low chance of bycatch
Disadvantage:
low yield
slow

Quality of catch: good quality as less compression, blood loss & quick harvest.
Environmental impact: potential bycatch of unwanted species if attracted to the bait/lure. ]]> 2022-02-08 06:33:32 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034775736 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034779476 Large catch]]> 2022-02-08 06:36:48 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034779476 200036753 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034783564 Similar to handling, but with a longer fishing line and on a moving vessel. A powered reel is used to hual in the line

Target species: Pelagic fast-moving fish

Advantage:
Low chance of bycatch due to moving vessel.
Disadvantage
Higher energy consumption due to moving vessel

Quality: high quality due to less compression & quick harvest of fish
Environmental impact: energy consumption from the ship.

Targeted species: tidal fish, benthic organisms

Advantages
Highly specific fish due by adjusting size of cages
Disadvantage
Traps can entangle unwanted species

Catch quality: Higher quality, one trap usually can only hold certain no. of organisms, preventing compression
Environmental impacts: trap & entangle unwanted species.]]> 2022-02-08 06:43:34 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034787655 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034794516 Pots are baited and animals must swim into the pot via entrances/funnels to access the bait

Target species:
Bottom dwelling organisms, scup, black seabass, eels

Advantages:
Culling rings can be added to allow undersized creatures to escape, though marine mammals and turtles can still be injured
Weak links and breakable lines can be added to allow entangled animals to break free without injury

Disadvantages:
Lines connecting pots to the surface buoys can entangle marine mammals or lacerate other cetaceans, though weak links and breakable lines can mitigate this issue]]> 2022-02-08 06:49:49 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034794516 200036753 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034798473 2022-02-08 06:53:25 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034798473 200084561 https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034814753 Nets can break when constantly dragged on the seabed]]> 2022-02-08 07:04:48 UTC https://padlet.com/200036753/g2he5km7pz6xcp8b/wish/2034814753
