Dear Kumaresdasan
The following references might provide pointers to answers to your
questions. By no means an exhaustive bibliography. Alpha-tocopherol
(vitamin E), naturally present in fish muscle, but can be enhanced through
the diet in farmed fish, appears to have a protective effect against loss
of carotenoid pigments.
