AN UNDERGROUND MUDFLAT PIPE NETWORK FISH CULTURE SYSTEM WITH SELF-RENEWABLE WATER BODY IS DISCLOSED. THE TRADITIONAL MUDFLAT AQUACULTURE GENERALLY ADOPT THE WAY OF PONDS, PURSE-NET AND STOCKING, WHEREIN, THE POND WILL DESTROY THE MUDFLAT TOPOGRAPHY AND THE ECOLOGICAL ENVIRONMENT, THE PURSE-NET IS VULNERABLE TO TYPHOONS, AND THE STOCKING IS SUITABLE ONLY FOR SHELLFISH CULTURE. THE PRESENT INVENTION COMPRISES FOUR PARTS: A RESERVOIR (4), AN UNDERGROUND PIPE NETWORK (1), INTERCHANGE PIPELINES (3) AND MANAGEMENT PONDS (2). THE UNDERGROUND PIPE NETWORK (1) IS USED FOR RAISING FISHES, THE CULTURE WATER IS SELF-RENEWABLE, THE INTERCHANGE PIPELINES (3) IMPLEMENTS WATER AND AIR EXCHANGE AND THE MANAGEMENT PONDS (2) IS USED FOR DAILY MANAGEMENT. THE SYSTEM IS SIMPLE IN STRUCTURE, EASY TO OPERATE, WHILE NOT DESTROYING THE MUDFLAT TOPOGRAPHY, AND IS PROTECTED AGAINST TYPHOONS, ACHIEVING A BALANCE BETWEEN THE EXPLOITATION AND THE PROTECTION. THE MOST ILLUSTRATIVE DRAWING IS FIG. 1.
