A Webster City business, Iowa’s First, has taken a proactive approach to circumventing the economic losses in livestock production by moving into fish farming. Mark and Jeff Nelson are producing hybrid striped bass in their unused hog facility. With the assistance of ISU Extension and Outreach they hope to create an aquaculture hub in central Iowa.
Due to this summer's extreme heat and dry weather, many pond owners are having issues with submerged plants, floating plants and filamentous algae, which are leading them to using aquatic herbicides that may be problematic for fish. Pond owners have a couple of aeration options according to Allen Pattillo, extension aquaculture and fisheries specialist.
The warm, early spring weather soon will encourage vegetative growth in the nutrient-rich waters of Iowa ponds. Pond owners need to know that wherever there is sunlight, water and nutrients, there will be some sort of plant growing. Effective management involves manipulating one or more of these elements to reduce or eliminate aquatic plants.
