The invention discloses a method for artificially
hatching loaches, which relates to the field of aquiculture. After laying spawns, loach parents are removed, only leaving the fertilized spawns laid by the loaches in a pond, and pond water is required to be clean and high in transparency, not to contain
silt and hostile and harmful creatures and be polluted, and to have the pH value of 6.5 to 7.5 and more than 4mg / L of dissolved
oxygen; the
hatching water temperature is 25 DEG C to 28 DEG C, the
water temperature difference does not exceed plus or minus 3 DEG C, a sunshade net is arranged over the pond to shade light during
hatching in order to eliminate
ultraviolet injury, a 'slow-fast-slow' mode is adopted as
water flow control in the pond, flow velocity is controlled at 0.1m / sec, flow is increased to 0.2m / sec before and after pipping, and after complete pipping,
water velocity is decreased to 0.1m / sec; when loach fries can swim parallel,
water flow is slowed again in order to prevent the loach fries from excessively consuming strength due to over-fast
water flow. The method for artificially hatching loaches, which is provided by the invention, is convenient to operate, and can prevent the loach parents from being injured, the effect of the spawning
induction method is good, the spawning induction rate and fertilization rate of the loach parents can be increased, and the number of laid spawns can be increased; the hatching rate and the fry rate are increased.
