Publishing their findings in the journal Reviews in Fish Biology and Fisheries, the authors argue that sensory deterrents can help reduce bycatch in some circumstances. However, variable results, caused by environmental factors and differences in species biology, make generalisations difficult. Further problems include the cost of equipment and potential for unintended broader environmental harm.Variability in study results highlights the importance that scientists and policymakers must consider all available evidence when designing bycatch reduction plans for fisheries. This study collates evidence of the use of sensory deterrents in fisheries, contributing to these decision-making processes.The study's authors conclude that it is likely multiple measures will be needed to address bycatch in most fisheries. They suggest that bycatch mitigation programmes should be made on a case-by-case basis, tailored to the needs of each fishery, species and local community needs
