Alternative bait

Changing the type of bait, such as switching from squid to mackerel, to deter non-target animals (such as sea turtles) that prefer one type of bait versus another (Watson et al. 2005).

The effects of hook and bait sizes on size selectivity and capture efficiency in Icelandic longline fisheries

Study Type: 

Field study in the wild

Location: 

Iceland

Target catch: 

Large bait decreased haddock catch and caught more large species except ling. Larger hooks lowered catch efficiency but had minimal effect in size selectivity

Effect on target catch: 

Large bait increased catch of large fish of all target species except for ling, and reduce catch of haddock. Increasing hook size decreased capture efficiency for all target fish species.Large bait decreased catch of small fish

Fishing Gear: 

Effects of Bait Type and Conspecific Attraction in Diamondback Terrapin (Malaclemys terrapin) Bycatch.

Study Type: 

Study in the lab

Location: 

Kiwah Island, South Carolina

Target catch: 

Blue crab (Callinectes sapidus)

Effect on bycatch species: 

Consumable bait had the greatest effect on terrapin entrapment relative to the presence of con-specifics and non-baited crab pots

Effect on target catch: 

Not tested

Fishing Gear: 

Experiments in the western Atlantic Northeast Distant Waters to evaluate sea turtle mitigation measures in the pelagic longline fishery. Report on experiments conducted in 2001-2003.

Study Type: 

Field study in the wild

Location: 

Atlantic

Target catch: 

swordfish and tuna

Effect on bycatch species: 

Reduced interactions

Effect on target catch: 

Swordfish catch decreased when circle hooks were baited with squid but increased when baited with mackerel. Tuna catch increased when circle hooks were baited with squid but decreased when baited with mackerel.

Bycatch species: 

Reduction technique: 

Fishing Gear: 

Field Study 723

Study Type: 

Field study in the wild

Location: 

Western North Atlantic

Target catch: 

Swordfish and tuna

Effect on bycatch species: 

Circle hooks decreased loggerhead and leatherback catch; even more effective for loggerheads when combined with mackerel bait

Effect on target catch: 

Circle hooks combined with mackerel bait increased swordfish catch by weight. With squid, decreased swordfish catch, increased bluefin and albacore tuna catch. Mackerel bait decreased bigeye and albacore tuna catch.
