摘要： PROBLEM TO BE SOLVED: To provide a system for producing high-quality bivalves at a low cost by differentiating each function of the production of minute algae as a feed for the bivalves, the growth of spats, the release of the spats, the collection of adult shellfish, and the cleaning of the bivalves before shipping, and installing a concentrated installation and distributed installations corresponding to each of the functions. SOLUTION: Each of the functions from the seed production of the spats to the shipping of the adult bivalves is differentiated and the installations corresponding to each of the functions are installed by combining a production center 10 for carrying out the production of the minute algae as the feed for the bivalves, and the seed production of the spats, plural seaside culturing sites 20 for releasing and growing the spats produced at the production center 10, and plural section centers 30 for culturing the adult bivalves cultured at the seaside culturing sites 20 by feeding the minute algae produced at the production center 10 in a short time to clean the bivalves.

摘要： PROBLEM TO BE SOLVED: To provide a method for using a fallow paddy field, which enables the use of the fallow paddy field in the state of a paddy field, the maintenance of the functions of the paddy field, and the production of products having high additional values. SOLUTION: This method for using a fallow paddy field, comprising culturing a micro-alga useful as a raw material for foods or medicines, culturing a micro- alga useful as a grass-inhibiting agent or fertilizer for paddy fields, or culturing a micro-alga useful as a bait for fishes or shellfishes and simultaneously breeding the fishes or shellfishes. Thereby, the products having high additional values can be produced using the fallow paddy field, and the employment of agrochemicals and chemical fertilizers in the paddy field can be reduced. Since the fallow paddy field is used in the state of the paddy field, the original water- storing function and ecosystem-maintaining function of the paddy field and the spectacle of the paddy field are not deteriorated, and the recovery of the fallow paddy field is also easy.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a herbicide and a fertilizer for paddy-rice plant cultivation with which an aquatic plant to be a herbicide and a fertilizer in a paddy-rice plant cultivation can be always in a luxuriant state in a paddy field during a paddy-rice plant cultivation and microalgae and duckweed being aquatic plants can be mass produced at a low cost while maintaining a high productivity. SOLUTION: A paddy field is divided by walls 14 and partition materials 15 to form a water reflux. Water is forcedly refluxed along the reflux route by a water wheel 16 and a carbon dioxide gas is supplied from a carbon dioxide gas feed opening 17 to water to simultaneously culture Anabaena of blue-green algae and Azolla. The cultured Anabaena of blue-green algae and Azolla are supplied as a herbicide to a paddy field 11 for paddy-rice plant cultivation during two or three months before or after rice planting in the paddy field 11 for paddy-rice plant cultivation and as a fertilizer after that. After harvesting of paddy-rice plant, the Anabaena of blue-green algae and Azolla are harvested, mixed with a compost raw material and made into a feed for fish and shellfish and used.
