Tilapia, hybrid striped bass, barramundi (“Australian sea bass”), yellow perch, sturgeon, and eel are examples of fish species well suited to closed recirculating systems. Marine fin fish culture is one of the world's fastest expanding aquaculture sub-sectors. Due to its high nutritional profile and strong demand in the seafood basket in both the domestic and international fish markets, fin fish has grown in popularity. The aim is to double the income of coastal fishermen and fish farmers.
Aquatic invertebrates such as oysters, clams, and mussels are farmed (i.e., cultivated and harvested) in shellfish aquaculture. Cultivation entails being involved in the raising process in order to improve productivity, such as frequent stocking and predator protection. By filtering contaminants, sediments, and nutrients from the water column, shellfish aquaculture operations actually improve water quality.
