Il premio Dyson, sezione Gran Bretagna, e’ stato assegnato a Dan Watson., diplomato alla Glasgow School of Art.

SafetyNet e’ un sistema di vie fuga basato su aperturre  ad anello nelle reti. Questi anelli permettono la fuga di pesce inferiore a certe dimensioni e limitano la cattura a haddock e whiting adulti, evitando cosi’ di dover ributtare in mare pesci piccoli senza interesse commerciale.  Gli anelli si aprono col movimento della rete, e sono dotati di luci che si accendono oltre una certa profondita’,  attirando il pesce verso le uscite, ma trattengono il pesce adulto.

The invention of “escape rings” that keep a net open and light up to guide immature fish to safety has won the U.K. leg of the James Dyson Award for recent Glasgow School of Art Graduate Dan Watson.

He now goes on to compete against the winners from 17 other countries, but the BBC reports he will launch the product whether he wins or not.

SafetyNet is designed to help trawlers capture mature haddock and whiting, and prevent other kinds of smaller fish being thrown back into the sea dead because they are unmarketable…

The rings harvest their own energy from the nets’ motion, meaning that once fitted the fishermen do not need to think about changing their batteries or switching them on and off.

The lights are activated once the net sinks to a certain depth, making the rings more visible and also stimulating the fish to swim towards them.

Because the devices are rigid they keep the surrounding net meshes open, preventing the gaps from closing when the equipment is under tension. Fish are often injured when this happens using standard equipment.

Mr. Watson said it would cost about £500 (about $790) for an average net using 20 rings, but they could be retrofitted and switched between nets. They could pay for themselves, he said, through incentives for sustainable fis
