Abstract
The present invention relates to the use of an astaxanthin pigment product obtained by semi-synthesis from marigold extract to substantially enhance the feeding and growth rates of commercially cultivated aquatic species when added to the feed mixture in concentrations useful in producing fish and shrimp coloration. More particularly, this product induces growth rates substantially greater than any currently available feed additive for salmon, trout and shrimp.
