Hooks-and-Lines

Fish are attracted to hooks-and-lines by natural or artificial bair placed on a hook, which captures the fish when it bites the bait. One or multiple lines may be used to catch pelagic, demersal, or benthic species. Different line and hook types are used depending on the target species.
<br><br>
<i>Set longlines</i> are used near the ocean bottom and consist of regularly spaced shorter lines, or snoods, attached to a long main line. <i> Drifting longlines </i> have a main line kept near the surface by floats, with baited hooks attached to long snoods. <i>Trolling lines</i> are towed behind a vessel at the surface or depth, and use baited hooks or lures. <i>Vertical lines</i> are attached to a sinker and have one or multiple hooks. <i> Poles and lines</i>, consisting of a baited hook or lure attached to a pole, are the gear type most frequently used by recreational fishermen. <i>Handlines</i>, such as those used for squid jigging, are vertically weighted lines attached to bait or lures; fish are hauled up into the boat when caught.

Effect on bycatch species: 

Integrated weight longlines paired with streamer lines eliminated surface foraging and shearwater catch by 97%; integrated weigh longlines reduced surface forager catch rates by 91% and unweighted longlines with paired streamer by 98%

Effect on bycatch species: 

High speed trolling with J hooks and artificial bait and slow trolling with circle hooks and natural bait resulted in less internal hooking, tissue damage and increase post release survival.

Target catch: 

Patagonian toothfish

Effect on bycatch species: 

Sperm whales interacted with longlines 25% of the time; orcas interacted only 5% of the time could remove half of the catch; fur seal interactions have declined since 2009

Effect on target catch: 

Catch rates were lower when marine mammals were present
