Abstract: A farming apparatus for aquatic organisms living in sandy soil, includes: a farming tank; and water feed pipes provided at a constant interval at the bottom of the farming tank; wherein the water feed pipes each have jet openings arranged at a constant pitch on the side faces. The farming apparatus is capable of continuously keeping clean the entire area of the sand layer which provides a living environment for crustaceans and other aquatic organisms living in sandy soil, so that high-quality aquatic organisms living in sandy soil can be produced at a high rate of growth and high density.
