The invention relates to a method for culturing
penaeus vannamei in a
cement pool by means of microecological preparations. The method comprises the steps that 1,
fresh water is inoculated with
lactic acid bacteria and EM
bacteria separately, culture media A are added respectively, culturing is conducted under the aerobic and normal-temperature conditions, filtering is conducted,
fresh water and a culture medium B are added for culturing respectively, and then the microecological preparations are obtained; 2, in a
water body in which the
penaeus vannamei is cultured, the
lactic acid bacterium microecological preparation with the concentration
ranging from 75 ml / m<3> to 100 ml / m<3> is added every day, the EM bacterium microecological preparation with the concentration
ranging from 50 ml / m<3> to 75 ml / m<3> is added
every three days, the
water temperature is controlled to be 28+ / 3 DEG C, the
salinity is controlled to be 20-35, the pH is controlled to be 7.8-8.4, the dissolved
oxygen is kept at 8 mg / L or above, and compound feed is put four times every day at 06:00, 11:00, 16:00 and 22:00 respectively. According to the method,
inoculation culture is conducted in the culture
pool by adopting the microecological preparations, the
weight gain rate, the
specific growth rate and the
survival rate of the
penaeus vannamei can be significantly increased, the feed coefficient can be significantly decreased, and the yield can be increased by 25% or above; in addition, the commercial penaeus vannamei is thoroughly cyan in body color, and after the commercial penaeus vannamei is cooked, the color is thoroughly red, and the color sense is enhanced.
