Larger aquatic plants or macrophytes include pondweed and milfoil. These plants are undesirable in aquasystems because they interfere with fish management (feeding and harvesting), compete with plankton for nutrients, provide shelter for undesirable fish, contribute to oxygen depletion and high ammonia levels when they decompose and contribute to water loss through transpiration. Drying and desilting of aquasystems every one or two years will keep the growth of aquatic plants in check.
