Fish Feeding Experiments
Many fish feeding experiments must be conducted in a controlled environment to prevent interaction of environmental effects, such as natural food organisms, temperature, and water quality, with the nutrient variable being studied in the experiment. For example, nutrient requirements cannot be determined unless nutrient consumption by fish is precisely known. Such studies are conducted in aquaria or tanks, indoors, with controlled temperature and water quality. Some studies, however, which involve evaluation of practical feed formulations or feeding regimes, should be conducted under conditions as similar as possible to the conditions where the results will be applied while at the same time allowing for accurate collection and analysis of data. These studies are conducted in experimental ponds, raceways, pens, and similar enclosures of water.
