Surrounding nets

Surrounding nets enclose fish in net from both sides and bottom, effectively preventing escape.
<br><br>
<i>Purse seine nets</i> have a purse cable running through purse rings hanging from the bottom edge of the net. This allows the net to be drawn closed when the cable is tightened. Purse seine nets can be operated by one or two vessels either coastally or on the high seas. <i>Lampara nets</i> are shaped like slings and lack a purse cable. Fish are trapped in the finer mesh at the center of the "sling." Lampara nets are almost exclusively used to catch species inhabiting surface waters. <i>Ring nets</i> are purse seine-lampara hybrids; they are shaped like lampara nets but have a purse cable. Like lampara nets, ring nets must be used close to the ocean's surface. <i>Beach seine nets</i> are set close to the coast and hauled in from land.

Study Type: 

Field study in the wild

Location: 

Portugal

Target catch: 

Sardine

Effect on bycatch species: 

Cetaceans were present during 16.9% of fishing events; encirclement led to common dolphin mortalities

Article: 

Study Type: 

Field study in the wild

Location: 

Kerala, India

Target catch: 

Not identified

Effect on bycatch species: 

Not statistically reported; study only administered a questionnaire that collected information on the structure and design of the Dolphin Wall Net (DWN)

Effect on target catch: 

None reported

Article: 

Bycatch species: 

Reduction technique: 

Fishing Gear: 

Study Type: 

Field study in the wild

Location: 

Papua New Guinea and Solomon Islands

Target catch: 

Skipjack and yellowfin tuna

Effect on bycatch species: 

Double-FADS caught larger bigeye tunas but the catch rate was slightly less than on normal FAD sets.

Effect on target catch: 

Fewer skipjack tuna were caught by number and weight. Yellowfin tuna catch was higher.

Fishing Gear: 

Study Type: 

Field study in the wild

Location: 

Western and Central Pacific Ocean

Target catch: 

Tuna

Effect on bycatch species: 

Only two out of 105 silky sharks were able to escape through the release panel. No finfish species escaped.

Effect on target catch: 

None reported

Article: 

Bycatch species: 

Reduction technique: 

Fishing Gear: 

Study Type: 

Field study in the wild

Location: 

Chesapeake Bay

Target catch: 

Finfish

Effect on bycatch species: 

. During the study, 21 sea turtles interacted with the control net, while only 1 interaction with the experimental net occurred, which was a significant difference.

Effect on target catch: 

There was no significant difference in the harvest weight or size selectivity of finfish between the two nets (control and experimental)

Article: 

Bycatch species: 

Reduction technique: 

Fishing Gear: 

Study Type: 

Field study in the wild

Location: 

Lake Opinicon, Canada

Target catch: 

Bluegill and other bony fish

Effect on bycatch species: 

The exclusion device with bars across the net significantly reduced turtle catch rates. All turtles were able to escape through the escape chimney.

Effect on target catch: 

Fish catch rates were not impacted by either excluder device. The majority (88%) of fish were retained when the escape chimney was used.
