FEED CONVERSION METHOD FOR BENTHIC ORGANISM, METHOD FOR CLEANING CULTURE POND OF TIGER SHRIMP, AND FEED CONVERSION AGENT FOR BENTHIC ORGANISM

PROBLEM TO BE SOLVED: To provide a method for forming, maintaining and recovering the medium function (soil fertility) of microbial reaction of the bottom mud of a tiger shrimp culture pond, and effective for remarkably improving a culture pond having low productivity, preventing injury by continuous culture, recovering a pond lost its culture potential by continuous culture and improving tidal land environment deteriorated by organic matter loading. SOLUTION: A method for converts either one or both of organic matters deposited on the bottom of a tiger shrimp culture pond and organic matters in the soil of the pond, concretely. The method provides a feed conversion method for benthic organism and a cleaning method for a culture pond or a tidal land by mixing or scattering amorphous hydrous iron oxide to the bottom. Further, a feed conversion agent for benthic organism, containing amorphous hydrous iron oxide and usable in the feed conversion method for benthic organism, is provided. COPYRIGHT: (C)2009,JPO&INPIT
