Mixed culture method for grass carp and loaches

Abstract

The invention discloses a mixed culture method for grass carp and loaches. The mixed culture method includes the steps of: dredging and disinfecting a culture pond, hardening the pond bottom, protecting the pond walls, paving bottom mud, planting water plants, reducing ammonia nitrogen level, putting the grass carp and the loaches; and therefore, the mixed culture mode of the grass carp and the loaches is achieved, the vertical space of the culture pond is reasonably utilized, and the utilization efficiency of the cultural water is improved; the water plants and land plants are reasonably planted, thus being capable of providing enough bait for the grass carp, and saving the cost for putting feeds; the loaches exist in the lower-layer space of the culture pond, thus playing a role in loosening cultural bottom mud and accelerating the growth of the grass carp; and humus can be used, which plays a role in purifying the water.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for mixed cultivation of grass carp and loach. Background technique [0002] At present, aquaculture factories still widely use a single species of fish farming method, which fails to efficiently and fully utilize the area in the vertical direction of the water body, resulting in a huge waste of space, which is not conducive to achieving high-density farming and improving economic benefits. Grass carp can feed on aquatic plants in natural waters, reduce feed input, save costs, and improve bait utilization efficiency. However, the growth of aquatic plants in water areas is affected by various aspects, such as dissolved oxygen, root growth status, etc. The growth environment should be adjusted to facilitate its growth; moreover, according to experimental observations, grass carp can grow 1 kg of meat by eating 15 kg of terrestrial aquatic plants, and 1 kg of meat by eating 60-80...
