Scallop potting with lights: A novel, low impact method for catching European king scallop (Pecten maximus)

This paper describes, for the first time, that scallops can be attracted into static fishing gear using LED lights. novel finding presents an opportunity development of a new, low impact method scallops. Traditionally, wild caught are primarily fished dredges and trawls. Due to their penetrative nature, interaction this towed with seabed cause significant damage sensitive marine habitats species. Diver have been alternative source, however, sector only supply limited quantities due logistical constraints. In study, we investigate potential illuminated standard commercial crustacean pots. We assessed effect light in range pot designs on scallop, brown crab, lobster crawfish, spider crab catches Cornwall between December 2020 February 2021. A total 77 strings were shot, deploying 1886 pots six treatment types. The grounds used trial traditionally potted crustacea not renowned scallop beds. Despite this, all treatments lights retained 518 recorded, 99.6% (n = 516) modified parlour (treatment F) most effectively, maximum catch rate 19 per string (23–24 string) 24-, number recorded single was 24. show simple inexpensive modifications existing present fishers augment environmental impact, premium product. Further refinement design needed enhance retention before commercially viable fishery established. discuss opportunities these new findings industry managers.
