Mechanical control methods mean using tools like rakes and shovels to remove aquatic plants.In Iowa, grass carp are typically stocked at four to eight 8-10 inch grass carp per surface acre, depending on the amount and type of vegetation present. Biological control typically involves an animal, like grass carp, that feeds on aquatic plants to control submerged plants.Those controls are biological, mechanical, cultural or chemical removal methods. Each of these plant categories requires a slightly different control management strategy. Effective management involves manipulating one or more of these elements to reduce or eliminate aquatic plants.Īquatic plants are categorized into four major categories that occupy slightly different habitats – algae, floating plants, emergent plants and submersed plants. Pond owners need to know that wherever there is sunlight, water and nutrients, there will be some sort of plant growing. During this time of year, known as the spring turnover, oxygen and nutrients get distributed throughout pond water, the sun gets stronger and the first algae begin to grow. The warm, early spring weather has prompted the growth of vegetation across Iowa’s nutrient rich soils – and soon it will encourage growth in the nutrient-rich waters of Iowa ponds.
