METHOD FOR IMPROVING PRODUCTIVITY OF ARK SHELL IN THE ARK SHELL FARM

摘要

PURPOSE: A productivity increasing method of ark-shell farm is provided, which can enhance the productivity of the ark-shell farm by improving the polluted bottom quality and water quality. CONSTITUTION: A productivity increasing method of ark-shell farm includes: a step of classifying the particles of steel-manufacturing slag which is less than 5mm; a step of covering the ark-shell farm including the polluted marine culturing ground with the classified steel-manufacturing slag; a step of mixing the classified steel-manufacturing slag with the polluted marine culturing grounds in the ark-shell farm. The steel-manufacturing slag not only prevents the secondary pollution by the suspended material but also improves the productivity of the environment-friendly ark-shell farm.
