Technique of soilless Culture of Loach

The traditional method of raising Loach is inseparable from the silt environment, and the previous several feeding methods are also artificially created a silt environment for Loach habitat and growth. However, Misgurnus anguillicaudatus has less habitat per unit area of silt, not only the utilization rate of water space is low, but also the efficiency of harvesting is not high. If there is no soil to raise Loach, there can be no mud. The foothold of this method is to use porous plastic foam or non-soil materials such as wood blocks and aquatic plants to provide a hidden habitat for Loach to drill holes. It can not only make multi-level three-dimensional use of water body, but also easy to catch commercial Loach.

Porous plastic foam

Drill several holes with a diameter of about 2 cm every 5-7 cm. Each piece of plastic foam varies in size, with a thickness of 15-20 cm, overlapping as a solid, and fixed. Let it float below the surface and not out of the water.

Porous wood or concrete blocks

The size, thickness and spacing of the foam are the same as those of the porous plastic foam, but they are arranged in the water after overlap, from the bottom to the top.

Water plants are hidden.

Water plants (water hyacinth, etc.) are placed in the pond and float on the water surface to hide the Loach from the sun. in hot summer, it can not only absorb the direct irradiation of strong ultraviolet rays on the Loach, but also adjust the water temperature. it not only provides a good habitat for Loach, but also can purify the water quality and improve the whole ecological environment in the breeding pond. The covered area of aquatic plants accounts for about 2 / 3 of the water surface.

Therefore, the water grass can be directly put in the water for the soilless culture of Loach, especially in large-scale culture, the production process of Loach is easy to manage, easy to operate and properly managed. The growth rate and survival rate of Misgurnus anguillicaudatus will be greatly improved.
