We got more crabs than Cromer in the Fens
Rings appear around the blob of orange sitting on a flat calm drain. When it falls flat, I pick the rod up, wind down and connect with fresh air.
The as-yet unanswered question is what impact they're going to have on the ecology of our rivers, where coarse fish already have cormorants, increasing numbers of other fish-eating birds and otters to contend with.
Crabs eat fish spawn. Some believe they are partly responsible for the decline in schoolie zander on the Middle Level and lower reaches of the Ouse. I have no idea whether this is true, but one thing's certain. Looking at how efforts to eradicate the American signal crayfish have failed, these things are probably here to stay.
