c) Fish 



The carotenoids of fish have been repeatedly investigated, but the isolation 

 of the crystalline pigments has only rarely been achieved. It can be regarded 

 as certain, however, that fish (skin, flesh, inner organs, eyes) almost invariably 

 contain carotenoids. Xanthophyll, carotene, astacin, and according to Lonn-
