 Electrofishing is used by the CRT to remove zander from canals | Debate is raging once again over the status of zander after contractors were criticised for removing and killing the predators in a canal marina. The Canal & River Trust (CRT) electrofished Diglis Marina on the Birmingham and Worcester Canal in Worcester, leading zander fans |
to question whether it would have any impact on established populations, whether it was a good use of CRT funds and whether other species caught during the operation were returned alive.
‘Futile’ culls
“It’s an exercise in futility,” said predator angler John Glover, who believes electrofishing actually boosts zander numbers because it tends to remove larger fish, leaving younger ones to thrive. He said waters which aren’t electrofished balance themselves out, leaving silverfish populations to remain naturally consistent.
Mr Glover, of Tusses Lure Division Angling Club, criticised the sporadic electrofishing of CRT waters as a money-making exercise for contractors. He said:
“It’s counter-productive and it’s not efficient. All it generates is more zander, and these small zander go on the rampage, which is what annoys the match anglers.”
Healthy canals
On stretches of canal run by Tusses Lure Division, where the CRT does not routinely remove zander, Mr Glover said the all-round fishing had never been better. Moreover, he added, a zander-fuelled boom in lure angling was bringing money to the local angling economy.
“The canals are the best I’ve ever known them for coarse fishing,” he said.
“I love roach fishing and I reckon it’s currently the best it’s ever been.
“We’re trying to encourage more matches on our stretches and I think match anglers would be pleasantly surprised. I’ve had 2lb roach out of the Oxford Canal and, in the same spot where we’ve caught half-a-dozen zander in a day, a friend and I have each had 100lb bags of bream in the summer!”
John Ellis, the CRT’s fisheries manager, defended the Worcester cull but said he was happy to have a debate about the way canal zander are treated. He said the fundamental issue was legislation, including the Wildlife and Countryside Act, which makes it illegal to stock or return zander to the water.
“If people want to change the law they should lobby the Environment Agency and Government,” he said.
“Shouting at the CRT is a bit like lobbying the police to change the law on speeding – Parliament changes the laws, not those who enforce them.”
Mr Ellis said fully enclosed stillwaters could legally hold zander and that the CRT would happily donate all its canal-netted zander to such venues for free, but very few waters meet the criteria or have applied for a licence. He said none of the 72 reservoirs under the CRT’s control was classed as fully enclosed.
Duty under the law
He added that the approach to non-native species had to be consistent, and that anglers couldn’t pick and choose preferred species to remain.
“We can be prosecuted if we allow zander to enter other waters,” he said.
“There’s case law involving the plant Japanese knotweed, where Network Rail was sued when it started growing in people’s gardens.”
Asked whether removing zander had any real impact on their numbers, he said work focused on stopping populations taking hold in previously uncolonised waters and had successfully eradicated zander on stretches of the Trent and Mersey and Sankey (St Helens) Canals. He said:
“Electrofishing catches fish as small as 10cm-15cm, so we’re reducing zander numbers and overall weight. Its overall effectiveness depends on how efficient and regular you are.
“I agree there’s not enough science on this subject, nor the money to undertake the research. The industry collectively needs to sit around a table and work out a future.”
Other concerns
Mr Ellis said about 100lb of roach and bream were caught during the cull at Diglis Marina, which cannot be fished, and were taken to a nearby Droitwich Spa AC stretch. Asked why MEM Fisheries, which he founded, was given the electrofishing contract, Mr Ellis said he left the business in 1997 and that an eight-strong procurement panel sat for all CRT tender jobs.
He said most of the CRT’s 250 tenant angling clubs support zander control, but stated he was in favour of a ‘Midlands canal zander zone’ which the trust proposed to the EA in 2015. No decision has yet been reached.
“I wish it was easy to legally create zander fisheries, because I think that’s ultimately the solution,” said Mr Ellis.
“That could include a small Midlands canal zone if people could sign up to reasonable compromises – including zander anglers, the EA, CRT, Natural England and wildlife trusts.”
Speaking as a non-executive director of the Angling Trust, Mr Ellis added:
“I’m sure it’ll come up at future meetings.”
