A light that makes nets visible to marine life
- 300,000dolphins and whales drown in nets each year
- 64%fewer turtles in lit nets
- 95%fewer sharks and rays
- 5,000lights on nets by May 2027
Fishers don't want turtles either, so we're building a cheap light that keeps them out.

A gillnet catches everything
Turtles can't see it, get tangled and drown. Our research on bycatch quantification

Questions
What is NOCATCH?
A wave-powered green light that helps turtles, sharks and rays avoid gillnets.
Do I get a NOCATCH light?
Only with the Founding Unit, which includes one from the first production run.
How much is shipping?
You pay 60% of the estimate after the campaign, and we cover the rest.
What's the puzzle add-on?
A $29 NOCATCH puzzle you can add to any reward, and you pay its shipping.
Why green?
Turtles, sharks and rays see green well, but most target fish don't react.
Why would a fisher use it?
Bycatch wrecks nets, and lit nets kept the same catch in trials.
When will the lights go on nets?
After the ocean test and pilot, aiming for 5,000 lights by May 2027.
What if a test goes badly?
We'll post it here, fix the design and test again.
Is my pledge tax-deductible?
Nope, a pledge pays for a reward, so it isn't tax-deductible.
