ASSEMBLED EEL-CULTURING POND HAVING HIGH DENSITY

摘要

PURPOSE:To improve yield of eel and reduce feed term of eel by half by controlling water amount, water temperature, illumination, feeding and male and female producing circumference, etc., according to instruction of computer. CONSTITUTION:A water supply port 3 served also as plural filters is fixed to the ceiling part 2 of an artificial pond unit 1 formed to a prescribed shape by a concrete, etc., and a wire net 5 is provided in the circumference of pond wall 4 to prevent escape of eel when the pond was filled with water and simultaneously oxygen-generating sends 6 are spread all over the pond bottom. Then a screw type automatic feed device 7 and blue illumination device 8 are adjustably provided at a ceiling part and independent artificial ponds equipped with water amount control device 9 are arranged in the longitudinal and transverse directions and the three-dimensionally superposed and water amount, water temperature, illumination, feeding and male and female-producing circumference, etc., are controlled by a computer.
