Crustaceous crunchtime

Testing whether various crustaceans are strong enough to pull the trigger. Kicking off this wee series with the common shore crab (Carcinus maenas), following later on will be an edible crab (Cancer pagurus) and finally a European lobster (Homarus gammarus). As bait, I will use a ground-up dough produced from fermented fishwaste to check how well these species will repond to its (hopefully) generous odour plume.
