Developing an efficient and profitable scallop fishery using new and innovative pot technology

Great scallop (Pecten maximus) is a highly valued seafood species with strong market demand. Traditional scallop dredge fisheries were closed in Norway in the 1990s, and commercial harvesting today is carried out mainly by divers. This project investigates whether light‑based behavioural manipulation can enable an effective and environmentally friendly alternative to dive‑based harvesting.

The project builds on new technology developed by Fishtek Marine, where specialised light sources and attractor systems make use of scallops’ sensitivity to light and their nocturnal activity patterns. The goal is to optimise pot design, light colour, and soak time to achieve consistent catch rates under Norwegian environmental conditions.

If successful, the technology could enable increased—and more area‑efficient—harvesting, create new income opportunities for fishers, and strengthen value creation in coastal communities, particularly in the Northwest.
