It seems a sensible thing that the authorities are doing. It appears that they are following a method that has been used before and if they can return the Tarn to it's original state with original species intact then that IMHO is excellent. We see invasion of foreign fish and plants very much common place now which is always at the detriment of our own species.Its good to see some positve action being taken. I do not think the fox hunting ban has anything to compare with this environmental issue IMHO.
think we also now have a growing problem with the introduction of American Signal Crayfish which, apart from them killing small fish and aquatic insects, also carry a disease to which they are immune but is killing off the British Freshwater Crayfish.
Let me clarify....
I agree totally that certain species need culling from time to time and have no issues with it. It is as you say a sensible thing for the authorities to be doing. The point I was trying to make was that at this time of media attention to a certain type of killing lots of other types of killing are abundant on the approval of some government or at least local government body. I am not trying to draw a comparison between fox hunting and the poisening of a few fish, as my opening statement says I do not want to start a thread on this topic. I merely find the fact that a government authority can be actively seeking to stop certain types of killing whilst continuing to support others a little profound. Or is it not about time we had some form of government paper telling us which type of animal we are supposed to be bothered about and which ones we should not give a second thought.
Obviously the "experts" have looked at this in depth, I wonder why Electric fishing as used in Trout farms is not being employed? perhaps it's to large or deep a Tarn? as I am not familiar with the topography I can't say. but this I think would have had a far less impact on the enviroment.This poisen will kill all forms of life and make the Tarn sterile, so the food chain will need to be re- established before reintroduction of the fish. Quite a long term exercise.
Worthwhile however if it preserves our Native species.
The signal crayfish is very tasty to eat and theoretically you need a special fishing licence to use a very efficient method of catching them, ie. A cycle wheel, a bit of net curtain and a lump of fish/meat or any other bait in the middle. If they were caught and eaten perhaps we would not have the problem. By the way, it is illegal to return a signal crayfish to the water once caught legally or illegaly. Better to eat em!
