Essex crabs

The drive home this evening was brightened up by a report on PM (Radio 4) about Chinese mitten crabs, and the damage they are causing along the Thames. Apparently, however, they are edible when they are sexually active.

When the interviewee from the Natural History Museum was asked by Eddie Mair when that was, the answer was that we don’t exactly know: but that when they feel the urge, they move towards more saline water; so¬† they decamp from their Chiswick Eyot burrows and make their way downstream to Deptford. The suggestion was that they should then be harvested and sold ~ I suppose to the Chinese.
