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.

Study Type: 

Field study in the wild

Location: 

Georges Bank

Target catch: 

Swordfish

Effect on bycatch species: 

Signficant differences in catch rates for blue sharks and pelagic stingrays between the two gangions, with more animals being caught on the monofilament gangions. No significant difference was found between gangions for mako sharks.

Effect on target catch: 

There were no differences in the mean length at capture, but signficantly more swordfish were caught on the monofilament gangions.

Target catch: 

Tuna and swordfish

Effect on bycatch species: 

Pelagic stingrays had higher catch rates on J-style hooks and survival rates of dolphinfish and escolar were higher when circle hooks were used (fall and spring respectively)

Effect on target catch: 

Catch rates of yellowfin tuna caught in the fall were higher on circle hooks. Yellowfin tuna were caught four times as often in the mouth when circle hooks were used in the fall.
