Prawn trawling is among the world's least selective fishing methods and there has been a great deal of work done over the past few decades to develop modifications that reduce unwanted bycatches. Much of this work has focussed on modifications at, or near, the codend (at the aft section) of trawls,...

Prawn trawling is among the world's least selective fishing methods, the unintended consequence being large quantities of bycatch. It is also a method that can disturb benthic habitats and use large quantities of fuel—a significant running cost for many fisheries. Issues of bycatch and fuel...
