报告了斑节对虾防病养殖模式的研究 ,采取消毒海水的半封闭养殖和消毒海水冲淡的半封闭式淡化养殖以及地下咸水和浓缩海水冲淡的封闭式淡化养殖 .由于养殖用水均无携带致死的对虾白斑病毒 .虾塘彻底消毒和使用经PCR和核酸探针检测的健康虾苗 ,养殖过程投喂配合饲料 ,并防止飞禽等偶然带毒入池 ,从而切断了白斑病毒传播途径 .放苗时 ,养殖用水起点盐度分别下调至 12‰~ 10‰、 8‰~ 6‰和 5‰~ 4‰ ;捕虾期间最终盐度下降至 6‰~5‰、 3‰~ 2‰和 2‰ .淡化养殖虾塘环境因子的变化范围为透明度为 58~ 4 0cm、水温为 2 3 0~ 30 5℃、pH值 7 8~ 9 0、DO为 4 8~ 7 6mg/L、COD为 4 0~ 7 6mg/L、NH4 N为 0 0 1~0 0 5mg/L、NO2 N为 0 0 0 1~ 0 0 5mg/L .水中和底泥弧菌数量的变化范围分别为 1 0× 10 1 ~8 0× 10 2 个 /mL和 2 0× 10 2 ~ 8 5× 10 3个 /g ;水中和底泥异养菌数量变化范围分别为 0 34× 10 3~ 8 6× 10 3个 /mL和 1 5× 10 5~ 8 6× 10 5 个 /g ,在养殖过程中 ,养殖前期的总菌数 <养殖中期>养殖后期 ,这与采取捕大留小养殖后期存虾数量减少有关 .
Reported on the prevention and treatment of P. monodon breeding farming model, to take semi-enclosed disinfection of sea water and disinfection of seawater dilute semi-enclosed desalination and underground salt water and concentrated seawater dilute closed desalination farming as water are not carried with death Of shrimp white spot virus shrimp pond thoroughly disinfected and the use of PCR and nucleic acid probe detection of healthy shrimp feed breeding process feeding compound and prevent birds and other accidental poisoning pool, which cut off the white spot virus transmission. , The salinity of the starting point of farming water was reduced to 12 ‰ ~ 10 ‰, 8 ‰ ~ 6 ‰ and 5 ‰ ~ 4 ‰, respectively. The final salinity decreased from 6 ‰ to 5 ‰, 3 ‰ to 2 ‰ and 2 ‰ . The desalination shrimp pond environmental factors ranged from 58 to 40 cm in transparency, water temperature from 230 to 350, pH value from 7 8 to 90, DO from 48 to 76 mg / L and COD to 40 ~ 76 mg / L, NH 4 N = 0 0 1 ~ 0 0 5 mg / L, NO 2 N 0 0 01 ~ 0 0 5 mg / L. The range of Vibrio parahaemolyticus in water and sediment was 10 × 10 1 ~ 8 0 × 10 2 / mL and 20 × 10 2 ~ 8 5 × 10 3 / g; the number of heterotrophic bacteria in water and sediment The range of variation was 0 34 × 10 3 ~ 8 6 × 10 3 / mL and 1 5 × 10 5 ~ 8 6 × 10 5 / g, respectively. During the breeding process, the total number of bacteria in the early breeding stage Later, this is related to the reduction in the number of shrimp kept in the late stage of catching small reservoirs.
