The next morning after egg laying 01:30 moving back to the parent shrimp breeding pond. Hatching density is not more than 50 ten thousand/m 3 The water temperature is 28.5 ℃, the light is dim, and no medicine is used during the spawning and hatching period. The eggs and larvae were gently agitated throughout the pond every 30 minutes. Collecting the larvae to a seedling emergence barrel when the larvae grow to flea larvae stage I, eliminating the larvae of the middle and lower layers after stopping air supply, taking the larvae with strong phototaxis of the upper layer, performing microscopic examination on the larvae without abnormal setae, counting, and then entering a seedling raising pond. And respectively counting the egg laying amount of parent shrimps, recording the egg laying period and counting the hatching rate.
TABLE 1 parent shrimp cultivation of Litopenaeus vannamei "Guantai No. 1
Spawning cycle Parent shrimp egg laying amount (Wan/tailed) Hatching rate (%)
Example 1 7-8 days 33.72±0.13 93.21±1.45
Example 2 7-8 days 32.58±0.21 95.32±1.28
Example 3 7-8 days 35.14±0.15 96.87±1.15
By adopting the parent shrimp breeding method, the spawning period of the parent shrimps is controlled to be 7-8 days, the spawning amount is more than 32 ten thousand per tail, and the hatching rate is more than 93%.
Comparative study 1
Based on example 3, the feeding weight ratio of female shrimp ovary stage I-VI clamworm, oyster and squid is adjusted, see Table 2, and the total feeding amount in each stage is the same as that in example 3.
