Invasive Species

Canal latest news

For those interested the following is an excerpt from a  copy letter received by our club secretary Neil from the Canal and River trust in answer to queries from himself about the presence of Zander in the canal system. It does at least lay out the legal position as per the law.

Thanks Neil,
I can confirm that zander are a non-native species as set out in the Import of Live Fish Act legislation. They are held under temporary license by the Trust and we are instructed to remove all zander caught as part of our day to day fisheries management activity e.g. in fish rescues or in fish population surveys. It is an offence to return them to the water if caught by rod and line.  Although I am not aware of any prosecutions in this regard I would have to advise clubs that this is the current law so realistically any zander caught must be killed to comply with the legislation.



Hello Trevor and Dennis We have found a new invasive non-native species Dikerogammarus haemophaphes, a close relative to the killer shrimp at 3 locations in the Grand Union Canal – 2 sites at Blisworth and 1 at Stoke Bruerne – yesterday. These sites were targeted following the finding of what is called “demon shrimp” in the Severn, Trent, Thames, Witham and West Midland canals. The shrimp is aggressive and poses an equal ecological threat to killer shrimp, and unfortunately prefers more silty substrates. There appears to be association with Zebra mussels. We are currently developing information/identification sheets; but the best fisheries management action for anglers is Check, Clean, Dry – see link below. Can you pass this message to your member angling clubs, and also let me know of other stakeholders on the canal. Our immediate concern now is the Ouzel and Tove, which we will be monitoring as soon as water levels allow. Any questions, give me a shout.
