In the last three decades, extensive coastal areas along the Yellow River Delta were converted into fish ponds for the cultivation of high value marine commercial species such as shrimps, abalones, and sea cucumbers. Widespread farming techniques required heavy inputs of commercial feeds for shrimp farming or fertilizers to increase benthic algae or primary productivity in abalone and sea cucumber farming. Such aquaculture practices have resulted in wastage of commercial feeds, increased sedimentation, and bacteriological/virological contamination and high concentrations of nutrients in the water column. Collectively, this resulted in a high mortality rate of the farmed animals due to oxygen depletion and diseases from viruses, bacteria and other harmful microorganisms.1,2 Uncontrolled or inadequately controlled application of antibiotics for disease prevention and treatment further contaminated the aquaculture product and posed health concerns to consumers.
