The advantage of loach soil-less aquaculture is that because loach inhabits in fine sand, the efficiency of catching at the time of sale is high, the taste is better than that of the loach raised in the mud, and the density of aquaculture is also four times higher than that of the loach raised in the mud. The loaches hatched in spring in the pond made of mixed soil can grow up to 15~16 centimeters at the end of the year. The soil-less culture technology of loach will be discussed below.
Preliminary preparations
1. Design of breeding ponds and nests
The breeding ponds are unused turtle ponds, hardened cement pond structures, with specifications of 15 meters in length, 10 meters in width and 1.0 meters in depth. Before breeding, the water inlet and outlet were simply improved by moving the water inlet to the top of the pool wall and connecting a PVC plastic pipe with a diameter of 6-7 centimeters at the water inlet, so that the water inlet pipe extends to the middle of the breeding pool by about 40 centimeters, and at the same time, installing a mesh cover on the drainage outlet at the bottom of the pool, to prevent the loaches from escaping.
Artificial fish nests with used bicycle tires, the collection of used bicycle tires washed, disinfected with 30 ~ 40 mg / liter of potassium permanganate solution soaked in 20 ~ 30 degree angle tilted uniformly placed in the bottom of the pool, placed in a density of 5 / ㎡. Used bicycle tires as a fish nest, soft, good shading performance, although lightweight but can be naturally sunk in the water, can provide hidden habitat for loaches, is more ideal for artificial fish nest 2.
