- Seven strains of white shrimp (Litopenaeus vannamei )were preserved this year. In the assessment of the urgent tolerance of the original environment of the preserved species, the E strain group performed the best and the B strain group performed the worst. Evaluate the effect of whether or not the eyestalks of female shrimps are cut on the fertility and subsequent breeding of shrimps. The results show that the effect of cutting eyestalks on female shrimps promotes maturation, mating, spawning and hatching, while female shrimps without eyestalks have a higher effect. The number of single-tailed eggs laid and the number of nauplius, and the final survival rate, but the two groups did not reach significant differences in the performance of fertility (α=0.05). White shrimp females without eye stalks had a higher survival rate and better salinity stress tolerance to PL12 seedling cultivation (P<0.05).
- The Taiwanese group of grass shrimp(Penaeus monodon) F2 produced a total of about 150,000 tails for intermediate breeding to become black-shell seedlings. After the water temperature and salinity stress test, they have been screened for cultivation and have reached an average weight of 2.81±1.15 grams. The Madagascar group F4 has been bred together. Batches of shrimp larvae have also been screened out through water temperature and salinity stress tests for grow-out cultivation and now have an average weight of 52.29±17.08 grams.
- There are currently 3 species of freshwater prawns(Macrobrachium rosenbergii ) collected, namely Banten, Jiadong and Jiuru. All of them have completed MrNV, IHHNV, D1VI, MrNV, Yeast (Metschnikowia bicuspidata) and Lactococcus garvieae ) And other 6 diseases, Banten and Jiadong shrimp species have been bred to breed F1 offspring, and fast-growing types will be selected for conservation and breeding in the future.
