The Blue Manna Crab is something that people love to eat. They can be caught from pots, by scooping them or by snorkeling for them. For the first time this year I gave snorkeling for them a go, and surprised myself. It’s a lot of fun, and with proper welding gloves you don’t get hurt either. There are a lot of these up and down the Rockingham Foreshore, at the right time of year.
