Size matters in lake survey
Size matters and with pike in Bassenthwaite Lake getting smaller warning signals are being triggered.
The fish population is used to assess the health of the Lake District’s fourth longest stretch of water and anglers are again being called on to record details of their catches.
Lake District National Park’s annual fishing survey has been planned to help experts assess the state of the lake. Previous results have revealed significant changes in pike length and weight.
Countryside team leader, Chris Tomlin, said studies by the Centre of Ecology & Hydrology, at Lancaster, had shown a “worrying decline” in the species’ size.
He explained: “Analysis on recorded catches for the 08/09 season showed the top weight was 12 pounds, considerably smaller than the maximum 20 pounds recorded in 07. The problem seems specific to Bassenthwaite as there are no corresponding declines in Derwentwater.
“As pike are top of the fish food chain, they are a good indicator of the health of the lake and, if changes are taking place, it is essential we find out more.
“Bassenthwaite has already seen the demise of Vendace, a rare white fish dating back to the Ice Age, and has a raft of measures in place to improve sediment and water quality.
“We are appealing to anglers to help monitor changes in the pike population, because it paints an accurate picture of what’s happening underwater. We are grateful to our fishing fraternity for their assistance in the past and hope they will continue to support us in this crucial exercise.”
Chris said Bassenthwaite was an idyllic place to fish, offering opportunities to see a rich array of wildlife, including the area’s world famous ospreys and otters.
He added: “Although there has been a slight rise in the cost of permits for fishing and other recreational use on the lake, some seasonal prices remain the same to encourage anglers all year round.”
