<P>PROBLEM TO BE SOLVED: To provide a method for efficiently producing seedling of sand-submerged bivalves, such as little neck clams, under the decline of resources wherein seedling production relying on spontaneous generation or discharge is artificially produced on land which is less susceptible to nature. <P>SOLUTION: Naturally or artificially-incubated larvae or rooted young shells of sand-submerged bivalves are housed in a simple rearing tank in which the earth is filled and rearing environments are created on land which is less susceptible to the marine environment such as ocean currents. Complex management is not required except for throwing in plant plankton regularly or irregularly, achieving the low cost and extensive production method. <P>COPYRIGHT: (C)2012,JPO&INPIT |
