Masters Theses & Specialist Projects
The objectives of this study were to determine naturally occurring concentrations of vitamin A1 and A2 in selected native fishes and, under laboratory conditions, to determine the possible role of beta-carotene and lutein in the synthesis of vitamin A by goldfish. The native fishes were selected to exhibit different feeding habits and were taken from different habitats (stream vs. lake) during different seasons of the year. In the laboratory, two possible precursors, beta-carotene and lutein, were incorporated into the diet to determine the role of these substances in the synthesis of vitamin A.
Species of fish differed in …
