Multiple overcrowded tanks of live crustaceans in busy retail shop

This busy retail shop had multiple tanks of live crabs and lobsters, some in quite dirty water. Observer "There are 10 tanks on display at the front of the supermarket (in front of a very busy & noisy main road). Behind the tanks on display there are more tanks (which are less visible from street level) - the conditions for the lobsters and crabs in these tanks are more over crowded; in one tank I saw around 12 crabs, sitting on top of each other, not moving and with limited space even if they wanted to move. All the lobsters have their main pincher claws bound shut, including those in tanks on their own. In all cases the crabs and lobsters were not moving - they seemed subdued. However species were not mixed together. The water in some of the tanks appeared quite dirty."
