ABSTRACT:
Procedures for feeding fish or crustaceans are disclosed which make possible monitoring the extent to which the administered food is actually eaten. These procedures utilize fluorescent dyes which are commingled with the food in order by their release into the culture water to indicate the extent to which the feed is being eaten. By administering food containing fluorescent dyes which when eaten cause the culture water to fluoresce, a direct measure of the food eaten is achieved. By administering food containing fluorescent dyes which when not eaten cause the culture water to fluoresce, a direct measure of the extent of wasteful overfeeding is achieved. By administering food containing both types of fluorescent dyes simultaneously, and measuring the ratio of their fluorescences, a sensitive measure of feeding activity is achieved.
