Portunus trituberculatus can be eaten steamed. Many people say that it is possible that Portunus trituberculatus in many coastal areas was frozen, and the ice inside was not completely thawed, which led to the water in the ice cubes entering the meat, which made the crab's taste rotten and the umami taste decreased, so it could not be steamed. But in fact, both fresh and frozen swimming crabs can be steamed, but the frozen swimming crabs should be thawed before steaming.
