Research Institute Develops Device to Reduce Attached Organisms on Sea Scallops

The National Institute of Fisheries Science announced that it has developed a device that can reduce the attached organisms growing on the shells of cultured abalone in an environmentally friendly way, and has achieved practical results that can be applied at abalone farms. The abalone attached organism reduction device developed by the Institute's South Sea Fisheries Research Institute utilizes discarded oyster shells as a substrate for attached organism larvae by placing them in a dedicated cage made of high-density polyethylene (HDPE) material and installing it in the cage at a water depth of 50 cm or less. As a result, the attached organisms decreased by up to 63.7% compared to ordinary cages. Most abalone farming in our country is done using the offshore cage method, and it is estimated that the commercial value decreases due to attached organisms, and the additional costs for removing them amount to more than 86 billion won annually. Based on this practical research, it is ...
