The family were having an interesting discussion with the two young children about whether they were going to eat them. The water quality in the river is very good, so pollution wouldn't be a problem. According to this article it's a good thing to catch and eat signal crayfish, which are an introduced species and have overwhlemed our native crayfish (similar to the red and grey squirrel problem). You're supposed to have a licence, though - I have an idea that you're supposed to have a licence to fish in waterways and rivers anyway.

Was going to ask about the crayfish. The ones we used to catch weren't as chunky as that and were white or translucent

I think the ones you're talking about might be the native crayfish?
It appears that they were! We used to catch them as kids :-)
