Local effort to reel in pesky catfish recognised at Biosecurity Awards

Bay of Plenty locals who are reeling in the region's pesky catfish problem scooped the top gong at New Zealand's Biosecurity Awards.

The event, held in Auckland last night, is now in its third year and attracted a record number of 70 entries.

The supreme award went to Te Arawa Lakes Trust for its project dubbed Catfish Killas, which was established late last year in response to an incursion of catfish in Lake Rotoiti.

The pest species prey on small native fish, eat fish eggs, compete with kōura (freshwater native crayfish) and stir up sediment.

Judging panel chair John Hellstrom said the judges were unanimous in choosing Te Arawa Catfish Killas as the supreme award winner. The group was also awarded the Community Pihinga Award for new initiatives or projects.

"The Catfish Killers manage the catfish population with the help of 48 fyke nets, catching up to 1000 catfish a week," Dr Hellstrom said.

Project co-ordinator William Anaru said nets were checked daily by volunteers, including students from 16 local schools, polytech Toi Ohomai, one early childhood centre, as well as lakeside residents and tourists.

One volunteer who attended the awards was 10-year-old Malcom Bailey, who had already caught more than 550 catfish in his spare time.

Mr Anaru said it was very easy for locals to get involved, "sometimes you don't even get wet," he said.

The catfish that were caught in the nets were killed and sometimes used as fishbait for snapper, fertiliser on the garden, or for those whose palate was that way inclined, the occasional fish was turned into a meal, he said.

"We've had a few requests from American chefs in Rotorua to cook them up and eat them and they know how to decorate them properly, I'm still trying to figure that part out ... you have to be pretty keen."

While it was early days, Mr Anaru said they were now catching less catfish in their nets, which suggested their biosecurity efforts were starting to pay off.

"The probably biggest change to biodiversity, just those catfish numbers have gone down, so hopefully we've caught most of them."
