LED illumination of gillnets has been used successfully to reduce sea turtle bycatch without reducing target catch. Studies evaluating their impact on the incidental capture of seabirds report conflicting results .
May increase ray bycatch (Bielli et al 2020). Effect on seabirds conflicting, depending on light colour, flash mode and species involved.
Further evaluation of the efficacy of net illumination on bycatch reduction for different sea turtle species as well as on other taxa, including: examining the effects of light intensity on wavelength sensitivity; the number of lights deployed per net panel; different LED colours (e.g., green versus violet); and environmental conditions (e.g., water visibility, sea surface temperature, lunar light; soak time and duration)..
Socio-economic factors to be evaluated include: the potential cost savings associated with a reduction in fishing gear damage through avoiding bycatch events; and the effect on target catch weight or size.
