This is audience participation, if your group that likes that sort of meeting!
Every member of the group thinks of a fish, that they like or are interested in. They write the name of the fish on a piece of paper and I will draw the the names out of a hat, then talk for a few minutes on that fish, in an interesting and amusing way.
I can talk for as long as you like, say 45 minutes or an hour - I'll give you some examples of subjects I can include:
fishmonger or supermarket
the difference between wild and farmed salmon
why are herrings so rare these days
where do anchovies go?
