An experimental study of gill net and trammel net 'ghost fishing' in the Algarve (southern Portugal) [PDF]

Marine Ecology Progress Series, 1997
Four 100 m lengths of both monofilament gill nets and trammel nets were deployed at depths between 15 and 18 m off the coast of the Algarve (south of Portugal) between April 1995 and June 1996. The nets were set on a natural rocky bottom with one end cut loose to simulate lost nets. Changes in net structure (net height, effective fishing area, movement,

Reducing discards in trammel net fisheries with simple modifications based on a guarding net and artificial light: contributing to marine biodiversity conservation

Scientia Marina, 2018
Experimental fishing trials with standard (control) and modified trammel nets were conducted to assess the possible reduction of discards. The standard trammel net was the commercial net used in the area (80 mm stretched mesh inner panel) targeting Sepia

UJI OPERASIONAL ALAT TANGKAP RAMAH LINGKUNGAN JARING CIKER (JARING TIGA LAPIS ATAU TRAMMEL NET)

IOP Conference Series: Earth and Environmental Science, 2017
Abstract The sweeping trammel net (ciker net) is operated by lowering the net in a straight line and then pulling the last end of the net with a ship moving in a full circle where the other end functions as a circular axis (M1 method). An alternative way is for the net to be lowered and then towed by the fishing vessel along two opposing
