The invention relates to a loach ecological cycle running water culture
system. The
system comprises a rectangular loach culture pond, a
drainage ditch, tubificidae culture ditches,
wetland purification trenches and a
clean water convergence trench, drainage pipes are arranged on the
pool wall of the rectangular loach culture pond, the
drainage ditch and the tubificidae culture ditches are arranged at the outer side of one end of the rectangular loach culture pond, and the
clean water convergence trench is arranged at the other end of the rectangular loach culture pond. The
wetland purification trenches are arranged at one side of the rectangular loach culture pond, and a
water body flows through the bottom
layers of loach culture pools, the
drainage ditch, the tubificidae culture ditches, the
wetland purification trenches, the
clean water convergence trench and the loach culture pools in sequence. According to the loach ecological cycle running water culture
system, by the adoption of the soilless running water culture mode, bottom mud is replaced with submerged plants, the loach inhabiting and
ingestion environment is optimized, waste water for culturing loaches is utilized for culturing tubificidaes, living bait is provided for the loaches, a wetland system is utilized for purifying water, the efficient cyclic utilization of the
water body is achieved, the loach quality is improved, and the loach output is increased.
