Hi,

I have fished Loch Ken for some 15 yrs now and the AS crayfish issue is of great concern. I have had dialogue with the authorities and Scottish Natural Heritage.
Whilst something is about to be done by these authorities, I would welcome all experiences regarding this issue and the potential for anglers not visiting the loch as a result of the As infestation.
I keep a boat there and have witnessed the potential ecological demise of the water over the last five or six years. The Loch is such a water, that provides good income to the local economy by the likes of myself and many others.
I am trying to build a case for the authorities to create a sustainable removal of the alien species that can and will alter the water in a most negative fashion.

Please respond with your views.

Andrew, the problem with removal, is its impossible for humans to stop the population growth again.

Eggs can be transported in from miles away via water birds, as an example. And because these crays are not in their natural environment, they have little threatening their success rate. I imagine Crays can spawn huge number of eggs in a very short space of time.

I commend you for at least trying, but in reality I dont see it being beneficial in the long run.

How edible are they ? Do you need a license to fish Loch Ken if you were putting down some traps ?
