Abstract
Prior research on the spiny lobster Panulirus ornatus (Fabricius, 1798) determined that intermediate levels of cholesterol are important in diets, but astaxanthin may not be. Here we examined how the growth, survival and coloration of spiny lobster were influenced by the inclusion of both astaxanthin (50, 60 and 70 mg.kg-1) and cholesterol (0.3, 0.4 and 0.5 %) in a two factor experiment. Overall, survival was 84.8% with no significant difference among dietary treatments. Lobsters grew the best when fed the diet containing the lowest cholesterol and greatest astaxanthin of the levels presented. The results of this study point out the need to examine the effects of dietary component addition across a range of inclusion levels simultaneously for multiple nutrients.
