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 penaeid-trawl fishery. These refinements involved varying bar spaces, escape-exit areas and guiding-panel lengths, and were compared against a conventional trawl. Catches of teleosts and M. latisulcatus largely remained unaffected by the changes…

A netting-based alternative to rigid sorting grids in the small-meshed Norway pout (Trisopterus esmarkii) trawl fishery
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
Bycatch reduction device in the Chilean hake (Merluccius gayi) bottom trawl fishery, using a rigid separation grid
Abstract The Chilean hake trawl fishery is one of the most emblematic fisheries in Chile. Considering the type of trawl gear used in the industrial fleet and the variety of species which cohabitates
Can a large-mesh sieve panel replace or supplement the Nordmøre grid for bycatch mitigation in the northeast Atlantic deep-water shrimp fishery?
Abstract The Nordmore grid is the principle bycatch mitigation device in many shrimp trawl fisheries. However, in several of these fisheries, bycatch is a problem because small sized fish can pass
Factors affecting elasmobranch escape from turtle excluder devices (TEDs) in a tropical penaeid-trawl fishery
TLDR
Fishery-specific research is required to determine the appropriate TED bar spaces that reduce catches of elasmobranchs while minimising the loss of commercially important species.
Connectivity between a spatial management network and a multi-jurisdictional ocean trawl fishery
Abstract Spatial management is often applied in penaeid trawl fisheries to avoid non-optimal size classes of target species, by providing areas of refuge from trawl fishing effort. Efficient

Mitigating the bycatch of giant cuttlefish Sepia apama and blue swimmer crabs Portunus armatus in an Australian penaeid-trawl fishery
TLDR
This study examined the utility of mechanical-separating bycatch reduction devices (BRDs) for reducing unwanted bycatches of Sepia spp.
Refining a Nordmøre-grid for a Brazilian artisanal penaeid-trawl fishery
Two experiments were done to assess and refine the Nordmore-grid in a canoe-trawl fishery targeting Xiphopenaeus kroyeri off southern Brazil. During experiment 1, a codend containing a small (1881
The effects of Nordmøre-grid bar spacings on catches in a Brazilian artisanal shrimp fishery
TLDR
The results confirm the utility of the Nordmore-grid for addressing a key bycatch concern among local fishers, and provide insight into ongoing development of appropriate modifications to improve selectivity in this, and other regional fisheries.
Evolving and devolving bycatch reduction devices in an Australian penaeid-trawl fishery
TLDR
This study assesses the relative utility of the latest versions of two generic BRDs that have evolved/devolved in an estuarine fishery and provides direction for their future refinement in this and other similar fisheries.
Using a modified Nordmøre grid for by-catch reduction in the Portuguese crustacean-trawl fishery
TLDR
The level of exclusion of the non-commercial by-catch is encouraging, although short-term loss of Norway lobster raises some concern with regards to fishers’ acceptance of mandatory use of grids.
Quantifying the effects of bycatch reduction devices in Queensland's (Australia) shallow water eastern king prawn (Penaeus plebejus) trawl fishery
TLDR
Despite the lowered prawn catch rates, the reduced bycatch catch rates are promising, particularly for S. robusta which is not permitted to be retained by the prawn trawl fleet and yet experiences considerable incidental fishing mortality, and is targeted in a separate licensed commercial fishery.
An assessment of Bycatch Reduction Devices in a tropical Australian prawn trawl fishery
TLDR
It is shown that there are BRDs that can be of major benefit to prawn trawl fishers in the NPF, by excluding much of the unwanted bycatch while maintaining catches of commercially valuable prawns.
Assessments of modified codends that reduce the by-catch of fish in two estuarine prawn-trawl fisheries in New South Wales, Australia
TLDR
The results are discussed in terms of the probable behaviour of fish and prawns in the modified trawls, the need for fishery-specific designs of by-catch reducing trawl modifications and the implications of introducing such designs into normal commercial practice.
Assessment and benefits of damage reduction in prawns due to use of different bycatch reduction devices in the Gulf of Carpentaria, Australia
TLDR
The economic value of reducing prawn damage was calculated from a combination of the percentage reduction in damage and the price difference between 10 kg “soft and broken” prawns and higher-priced, finger-laid prawned packs, which was more than the cost of the BRD.
Modifications to reduce bycatch in prawn trawls: A review and framework for development
TLDR
It is shown that inherent variabilities among differentfisheries greatly influence the types of designs that need to be applied and although some designs have the potential for application across different fisheries, significant modification and re-evaluation are often required.
