Traps

Traps are baited or nonbaited stationary devices set on the bottom or, less frequently, in midwater. Fish enter the trap freely but are subsequently prevented from leaving. Large traps are more common in coastal waters while smaller traps may be deployed to greater depths.

<i>Pots</i> consists of cages or baskets used to target shellfish, cephalopods, crustaceans, and reef fish. Pots are placed in multiple sets and the location of each pot is marked with a surface buoy. <i>Fyke nets</i> and <i>stow nets</i> are fixed to the bottom and rely on currents to bring fish into contact with them. Additionally, fyke nets use "wings" to guide the fish into mesh bags, where they are captured. Both types are most commonly set near shore. <i>Barriers, weirs, fences</i> and <i>corrals</i> are used in tidal areas and span the entirety of the water column. Fish enter through a narrow opening and are then trapped in a holding compartment.

Study Type: 

Field study in the wild

Location: 

New Jersey

Target catch: 

Crabs

Effect on bycatch species: 

Modified traps with a 5X10 cm rectangular frame caught 2 out 15 terrapins during 1992 and 5 out of 51 terrapins during 1995 (remainder caught by unmodified traps)

Effect on target catch: 

Crab catch rates were 11% higher when the 5x10 cm excluder design was used in 1994 (multiple sites) and 49% higher in 1995 (single site)
