PotLight

A rugged, minimalist fishing light for trap based fisheries

THE CHALLENGE:

More efficient low-impact fishing

As fishers aim to increase returns without expanding effort or footprint, light-based attraction offers a smart, simple, and low-impact solution for modern pot fisheries.

Pot fisheries have traditionally struggled to match the catch efficiency of gear like gillnets due to their more localised attraction range and reliance on bait to draw fish into traps. Unlike gillnets, which passively entangle fish, pots depend on triggering foraging behaviour—typically through olfactory cues from bait.

OUR SOLUTION

Potlight

Across multiple fisheries, the addition of underwater lighting has been shown to dramatically increase catch rates. PotLight works by leveraging either by phototaxis (simple light attraction) or triggering a predatory cascade. For example, krill are strongly drawn to white light which draws in predators like cod that are stimulated by the movement of prey.

Unlike bait, pot lights have a 360-degree attraction radius, remains effective for as long as the battery lasts and doesn’t degrade like traditional bait. This gives pots a longer effective fishing window and allows them to compete with—and in some cases outperform—gillnets, while remaining selective and low-impact.

Key Features

Effectiveness

Proven with multiple species including: snow crab (Chionoecetes spp), cod (Gadus spp.) ; European spiny spider crab (Maja squinado); Cuttlefish (Sepia spp.); Scallops (Pecten spp.); Gurnards (Trigla spp.); Prawns (Penaeus spp.)

Built to last

Rated to 500m depth. Durable polycarbonate housing with double-sealed waterproofing handles harsh commercial use.

ADDITIONAL BENEFITS

Bait-less fishing: Reduced operational costs
Shorter soak times: Reduces risks of marine mammal entanglement
Fewer pots needed: Elevated catch rates reduce gear requirements
Improved safety: During rough weather, longer soak times provide confidence that gear is still working

ACCESSORIES

Fit-and-Forget Design

Activates on water contact, no buttons or setup. Compact and easy to clip onto pots without affecting stacking or deployment.

Safe & Non-Disruptive

At only 25g in water, PotLight doesn’t interfere with gear handling. It uses sealed alkaline batteries—safe for storage and deck operations.
