Sorry, but I'm not exactly sure where you concern is? If the shrimp is raw, then as long as it was frozen previously, it's fine. If it's shrimp as part of a diet for lions, that's fine too. If it's that the shell is still on the shrimp, that is fine as well. Remember Lions main food in the wild is other fish, which scales and bones are much harder to digest then shrimp shells. If it's that the Lion is eating a large quantity of food, (lots of shrimp before your able to feed the eel), then that is a concern, as fatty liver disease stems from not only feeding the wrong foods (live freshwater fish), but also from overfeeding.
