In this study, discussed the method to simulate the bottom environment of sublittoral muddy bottom under the breeding, which use for culture of fauna in muddy bottom. In the case of same density but diffferent grain size of substram, showed that same moisture content approximately in each grain size at larger quantity of seawater, although showed that high moisture content in coarser grain size at smaller quantity seawater like in aquaria. In the case of different specific gravity of muddy substram, showed that high water content in each quantity of seawater at lower specific gravity. But muddy substram in low specific gravity couldn't hold against the decrease of moisture content with consolidation. These facts suggested that factors of substram to simulate the muddy bottom environment for the aquaria were as follows : lower specific gravity of substram, coarser grain size of substram and form of substram, since kept high level on porosity and avoided the effect of consolidation.
