Fish in the River Aire

River Aire Fish 2012

Kevin Sunderland, our Chairman, had been busy. He has produced an excellent paper on fish populations in the River Aire. The latter part relates to each species of fish and where it can be found. The first part is a bit more general and may be of interest to those who aren’t particularly fish people.

An edited version of this report appeared in The Naturalist  No 138 (2013).

Invasive Species – Law Commission report

11 February 2014, Today the Law Commission published its final report on the control of invasive non-native species. See the Law Commission Wildlife Law project pages

Reference number: LC342


Law Commission wildlife project and the species control report

In July 2011, the Law Commission began a project on wildlife law. Its terms of reference were: to review the law on the protection, management, usage and welfare of wildlife in England and Wales, and to make recommendations for its simplification and modernisation.

Invasive species research – your help needed (2)!

Dear readers,

From: Nigel Taylor

Message: Dear Sir/Madam,

I am a new PhD student at the University of Leeds, investigating the
impacts of and interactions between invasive species. I am focusing on the
signal crayfish and Chinese mitten crab.

It seems as if the River Aire could provide some interesting field sites
where these two invaders may meet, with crayfish moving downstream and
mitten crabs moving up. Unfortunately, published data on the invaders’
distributions is scant.

I was wondering if you could provide any information on these two species
in the Aire. Any anecdotal sightings (from informal surveys, residents near
the river, angling clubs etc.) would be very useful. If you have no
information at present, do you have a mailing list or way of circulating my
request so I can be informed if any river users see these species?

Many thanks in advance for your assistance.

Nigel Taylor

Invasive species research – your help needed!

Dear readers,

I’m an ecology PhD student at the University of Leeds and as part of my research I’m investigating the impacts of aquatic invasive species in the UK. Animals such as North American signal crayfish, zebra mussels and killer shrimp and plants such as floating pennywort are spreading through our waterways having been accidentally introduced from other countries. Species such as these can cause serious damage to river banks and water pipes and are responsible for dramatic declines of our native flora and fauna.

In the absence of any other form of control, the only way we can reduce the impact of these invasive species as well as diseases that they may introduce, such as crayfish plague and koi herpevirus, is to ensure that we do all we can to prevent their further spread.  Disease organisms and invasive species in their smaller juvenile stages may be accidentally spread between waterbodies on boats, vehicles, clothing and fishing equipment. We are seeking your help to try and get a better understanding of current fishing practices so we can identify possible ways to prevent their spread.

We are therefore distributing questionnaires to anglers as well as canoeists and kayakers to find out more about the rivers that they are visiting and the kit that they are using at each site. This will enable us to see whether there are any areas where the risks from invasive species are likely to be greatest so that awareness campaigns and preventive measures can be targeted to those areas to prevent future outbreaks.

The questionnaire is here: I’d be very grateful if you could email the link to the questionnaire around your trust members. The questionnaire takes 5 – 10 minutes to complete and all answers are completely anonymous. Everyone who completes the survey is given the opportunity to enter a prize draw to win a £50 voucher for AnglingDirect online tackle shop.

Please let me know if you’d be willing to help with this. If you require any further information from me, please do not hesitate to ask.

Best wishes,

Lucy «email»
