Refining a Nordmøre-grid bycatch reduction device for the Spencer Gulf penaeid-trawl fishery. [PDF]

PLoS ONE, 2018
Incremental refinements were made to a generic Nordmøre-grid to minimise bycatches of blue swimmer crabs Portunus armatus and giant cuttlefish Sepia apama, while maintaining catches of western king prawns Melicertus latisulcatus in the Spencer Gulf ...

Can vertical separation of species in trawls be utilized to reduce bycatch in shrimp fisheries? [PDF]

PLoS ONE, 2021
Several shrimp trawl fisheries use a Nordmöre sorting grid to avoid bycatch of fish. However, small fish can pass through the grid. Therefore, the retention of juvenile fish often remains an issue during shrimp trawling.

Effect on catch efficiency and bycatch by introducing an Excluder device in the trawl fishery for lesser sandeel (Ammodytes marinus). [PDF]

PLoS ONE
Sampling of the North Sea trawl fishery for lesser sandeel (Ammodytes marinus) showed that 96% of the catch weight consisted of the target species, and experimental sea trials demonstrated that the observed small bycatch percentages of haddock ...

A netting-based alternative to rigid sorting grids in the small-meshed Norway pout (Trisopterus esmarkii) trawl fishery. [PDF]

PLoS ONE, 2021
A new bycatch reduction device, termed "Excluder", is presented as an alternative to a traditional rigid sorting grid, mandatory in the small-meshed Norway Pout (Trisopterus esmarkii) trawl fishery in the North Sea.

Vitality insights of fish escaping from a sorting grid installed on a bottom trawl net [PDF]

Scientific Reports
Sorting grids to exclude the juveniles of species targeted by bottom trawl fisheries from the catch are among the most promising solutions to reduce discards.

Smaller bar spacings in a Nordmøre grid reduces the bycatch of redfish (Sebastes spp.) in the offshore Northern shrimp (Pandalus borealis) fishery of eastern Canada

Aquaculture and Fisheries, 2023
The offshore Northern shrimp (Pandalus borealis) bottom trawl fishery in eastern Canada currently uses 22 and 28 mm bar spacing Nordmøre grids to limit bycatch from using small mesh codends.

Benefits of conventional anterior codend meshes turned 90° in an Australian trawl fishery are limited to an improved quality of Neoplatycephalus conatus

Frontiers in Marine Science, 2022
Turning conventional diamond-shaped meshes 90° (‘T90’) in trawl extensions or codends is a simple modification for consistently increasing lateral openings and has improved size selection in several European fisheries.

Juvenile and Trash Fish Excluder Device (JTED) for Taiwanese Bottom Trawl

Fishes, 2023
Juvenile and trash fish excluder devices (JTEDs) are used to mitigate the ecological impact of trawling. Trawling has a large ecological footprint in Taiwan.

Effects of using bycatch reduction devices on the Colombian Caribbean Sea shrimp fishery

Ciencias Marinas, 2008
Effects of the fisheye bycatch reduction device (BRD) and turtle excluder device (TED) on shrimp retention and bycatch reduction were assessed, aiming to increase sustainability and attenuate the ecological impact of shrimp trawls in the Colombian ...

Flow Field Pattern and Hydrodynamic Characteristics of a Grid Device Made with Various Grid Bar Spacings at Different Inclination Angles

Journal of Marine Science and Engineering, 2023
The grid is a crucial component in constructing grid-type bycatch reduction devices. The grid’s structural characteristics and orientation significantly impact the hydrodynamic characteristics and efficacy of the separation device.
