The invention relates to a method for breeding second-season
litopenaeus vannamei in an
overwintering mode with a
greenhouse. The breeding period is from the middle ten days of September to May in the next year. The method includes the steps of 1, implementing the key technology of releasing
shrimp larvae before installing a
greenhouse film in the first season, wherein the
shrimp larvae are released in September in advance, and when the
water temperature is reduced to 25 DEG C, a
greenhouse frame is covered with the light transmitting PVC film; 2, implementing the key technology of intensively marking the
shrimp larvae and then breeding the
shrimp larvae in a separated mode, wherein a pond accounting for 10-25% of the total breeding area is harvested first in the first season to intensively mark the
shrimp larvae of the second season. Preferably, part of original pond water at high temperature in the first season is introduced into water for releasing the
shrimp larvae in the second season to ensure that the shrimp larvae adapt to the
water temperature; in the whole
overwintering stage, the greenhouse is used for controlling the
water temperature to be 22-32 DEG C, and the most suitable temperature is 25-30 DEG C. One season production is added compared with common
prawn breeding in the greenhouse,
litopenaeus vannamei in the first season is harvested at the market demand peak,
litopenaeus vannamei in the second season is harvested 20 days earlier than that bred in a pond without a greenhouse, the
economic benefits are increased, and the requirement of citizens is met.
