STUDY TO HELP OUR KNOWLEDGE OF RIVERS

As anglers we enjoy our pastime, yet it is under threat from reduced runs of fish. Why?
There are many reasons, such as pollution, global warming, food source, etc.
The food chain is an important aspect for young fish, particularly
salmonoids.
Most of the species and communities in rivers have a limited range of temperature tolerance. An increase of 2-3C, along with changes in flow, could see some species, such as larval insects like stoneflies or mayflies, change distribution, decline in population or even become extinct.
The diversity of insects in a river has often been used as an indicator of overall ecosystem health because they are critical in the food chain.
A reduction in their abundance could have a serious knock-on effect for species such as fish, which rely on these insects as a food source.
The Carmarthern Fishermen's Federation (CFF), in partnership with the Environment Agency (EA), have set up a sampling project on the rivers of Carmarthenshire which, hopefully, will increase the knowledge about insect and invertebrates, etc, in our rivers and streams.
The CFF will be collecting and monitoring on the rivers and streams while the EA will evaluate the findings. Originally, five teams were created and training under an EA Wales biologist began in June 2006.
The scheme is coordinated by EAW together with CFF's Brian and Gethyn Thomas.
The CFF may need to recruit further teams and also are always looking for volunteers to help with other work on the river banks of our county.
They are working closely with the EA on all matters regarding improving our rivers and any help is appreciated.
You can also become a full member of the CFF and attend meetings and vote on some of the initiatives arising from time to time. Put something back into angling.

RIVERS
ONCE again the weather changed towards the end of the week. The Tywi was running high and coloured and a few fish were taken. One high spot was the catch of a magnificent double-figure sewin by Cerith Booth, a member of the Llandadog Angling Association. It was taken from the club water and weighed
15lb 5oz. This was Cerith's first double sea trout.
