Fishing net "escape rings" that light up to help small creatures elude takeover have been picked as this year's UK leader in a high-profile pattern engineering competition.
Dan Watson's plan is written to make fishing more sustainable.
The Glasgow School of Art connoisseur will right away face finalists from 17 other countries is to general James Dyson Award.
He skeleton to launch the product in any case of the outcome.
SafetyNet is written to help trawlers takeover developed haddock and whiting, and stop other kinds of not as big fish being thrown back in to the sea deceased since they are unmarketable
"The gadgets fit in to trawl nets and they cut down on the bycatch of youth fish and moreover the incorrect kind of fish," Mr Watson told the BBC.
"The rings fit in to the 'cod-end' of the net - the segment where all the fish are kept - and they essentially take advantage of fish poise and their earthy size to guide a few to safety whilst gripping the other ones in. They deed as kind of crisis elude sign."
The rings collect their own appetite from the nets' motion, meaning that once propitious the fishermen do not must be consider varying their batteries or switching them on and off.
The lights are activated once the net sinks to a established depth, creation the rings more manifest and moreover sensitive the fish to float towards them.
Because the gadgets are stiff they keep the surrounding net meshes open, preventing the gaps from shutting when the apparatus is beneath tension. Fish are frequently harmed when this happens using typical equipment.
The gadgets are written to be propitious to existing nets.
Mr Watson mentioned that the median net would need about 20 of the rings costing a complete of about 500 - but he updated that over time they should pay for themselves.
"There are incentives trustworthy to using tolerable fishing gear," he said
"For example if it is used the authorities can give fishermen additional days at sea that allows them to grasp more fish. It can moreover be taken off one net and put onto a new one so it lasts a long time."
Mr Watson has won 1,000 for being picked as the UK champion.
A row of 3 judges choosen his access over alternatives inclusive a steam-enhanced scraper used to eliminate wallpaper; a double-walled mop that keeps liquids prohibited and fingers cool; and a "flash heater" written to provide breast divert from HIV positive mothers to stop them fleeting on the pathogen to their babies.
The general endowment includes 10,000 in money for both the leader and their university department.
Whatever the outcome, Mr Watson mentioned he programmed to use the money he had already won to serve rise his prototypes before presenting them to nautical administration organisations that he hoped would help launch them as a blurb product.
BBC technology match Rory Cellan-Jones was one of the judges.
