Over 1000 fish traps were deployed in a fishery-dependent survey in New South Wales, Australia. Standardised catch rates indicate that the incorporation of magnets into fish traps significantly reduced incidences of elasmobranch bycatch (mainly Brachaelurus waddi) by over a third, while increasing the amount of target fish caught by an equivalent amount. Together these results suggest that magnets can be used as an effective bycatch reduction device that reduces incidences of elasmobranch bycatch while increasing the profitability of fish traps for fishermen. Future studies should aim to replicate these results in areas where different species of elasmobranchs occur.]]> Thu 25 Jun 2020 15:56:41 AEST ]]> Behavioural response of benthic elasmobranchs to a neodymium magnet under controlled laboratory conditions https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54262 Thu 15 Feb 2024 12:25:04 AEDT ]]>
