通过实验装置和实验方法设计,在人工控制的水域环境条件下,以每批100尾凡纳滨对虾(Litopenaeusvanamei)虾苗进行虾苗对光照强度、水温、溶解氧含量和盐度单因子适应性实验,以及对温度和盐度、温度和溶解氧的双因子正交实验。经过对实验数据的分析,得出虾苗有较强的趋光性,虾苗的适光范围为130～1060lx;虾苗的耐温范围较广,适宜温度为17～23℃,最适温度为20～23℃;虾苗的耐盐范围较广,适盐值为15‰～35‰,最适值为24‰～26‰;耐受氧浓度一般不能低于4.5mg/L,最适溶解氧范围为6～6.5mg/L以上。在对双因子正交实验的数据方差分析时,发现温度对虾苗的影响极为显著,盐度和溶解氧的影响次之。
Through experimental design and experimental design, under the condition of artificial control of water environment, shrimp seedlings of shrimp (Litopenaeus vannamei) were subjected to one-factor suitability of light intensity, water temperature, dissolved oxygen content and salinity Experiments, and two-factor orthogonal experiments on temperature and salinity, temperature and dissolved oxygen. After the analysis of the experimental data, shrimp seedlings have a strong phototaxis, shrimp seedlings suitable range of 130 ~ 1060lx; shrimp temperature range is broader, suitable temperature is 17 ~ 23 ℃, the optimum temperature is 20 ~ 23 ℃. Shrimp seedlings tolerated a wide range of salt tolerance, suitable salt value of 15 ‰ ~ 35 ‰, the optimum value of 24 ‰ ~ 26 ‰; tolerance oxygen concentration generally can not be less than 4.5mg / L, the optimum range of dissolved oxygen 6 ~ 6.5mg / L or more. In the two-factor orthogonal experiment data analysis of variance, we found that the temperature on shrimp seedlings is extremely significant, followed by salinity and dissolved oxygen.
