Dikerogammarus villosus Loose in the Broads

Looks like it has spread out of Grafham and the sites in Cardiff Bay and appeared in Barton Broad.

Seems unlikely that trout anglers would have spread it - were the biosecurity restrictions on boating in the affected venues tight enough?

How about a vote on the most likely cause of the transfer, the options being :

 

1. Transmission through anglers nets (legal)

 

2. Transmission through anglers nets (illegal)

 

3. Transmission through canoe / kayak access.

 

4. Transmission through human contact (ie, welly boots on the ground)

 

5. Transmission through other environmental factors (natural spread)

The other infected sites are game fishing sites - transfer on tackle to a coarse fishing venue is therefore unlikely. They're all boating sites, though. Yachties, I would say, not paddlers.

Yeah, I can see that a sailing yacht or powerboat might get transported overland and transfer the parasite in its bilge. But they also do zander and pike fishing on Grafham Water which should not be discounted.
