Factors limiting primary productivity in a large, eutrophic farm pond.
Farm ponds are small man-made resevoirs used for watering of farm animals, irrigation and fishing. Because of their small size, farm ponds are susceptible to rapid eutrophication which can cause growth of noxious or poisonous algae, unpleasant odor from decaying plant material, and loss of aesthetic value. Farmers are interested in farm pond management practices to produce high yields of fish without unnecessary algal growth.
