They can only survive for a little while (20 years, which is nothing to an orca). The dead fish that they are fed is extremely bad for their digestive system. The chlorine in the pools leads to many orcas developing a skin disease known as papillomatosis. The lack of depth in the pools means that the collagen in their dorsal fin flops can't harden, and the dorsal fin flops over. The sickly condition that all captive orcas are forced to live in creates an inadequate substitution for their natural environments; hence, the orca's life is shortened.
