it depends on which kind of crab.
many crabs would eat herrings.
crabs, being widely an omnivorous scavenger, eat just about anything that falls to the sea floor. Some crabs are predators and hunt small fish, which would include herrings. Of course, there are some crabs which are herbivores, which would stay away from them.
I wouldn't suggest feeding pickled or preserved herring to pet crabs though, the chemicals used in the preservation would probably kill them.
Crabs usually eat small organizms, and tiny food particles. (This is what they naturally eat, but they will eat practically anything, whether accidentally dropped of a dock or strapped to a trap.) Crabs cant open mussels, their shells are simply too strong.
Yes they can ! :) It might surprise people that about half of a crabs diet is plant matter, but that doesn't mean you should start putting rotting wood into your crab pots just yet. The other half of a crabs diet consists of any animal matter that it can scavenge. This is made up primarily of fish matter, shellfish, snails, worms, fungi and bacteria. Contrary to popular belief crabs are more partial to fresh fish than rotten fish. The later being popular with crab anglers due to the belief that crabs can find rotting animal materials because of the smell.
