摘要
单细胞藻类是鱼、虾、贝类等苗种生产的重要基础性活饵料．探索单细胞藻的培育新技术对于解决饵料藻类生产中的诸多问题具有重要的现实意义．远红外纳米陶瓷具有改变水分子团簇结构诱发生物效应的功能．本试验在叉鞭金藻（Dicrateria sp．）培养瓶中放入远红外纳米陶瓷材料一枚，其他培养条件与对照组相同，在培养结束时，置入纳米陶瓷的试验组的最高藻密度为345．3×10^4—397．8×10^4cells／cm^3，而所有对照组在平台期能达到的最高藻密度为293．8×10^4～323．0×10^4cells／cm^3，平均增长约20％，试验组达到最大密度的时间比对照组达到最高密度的时间提前了2-4d，试验组与对照组存在显著性差异，表明远红外纳米陶瓷可促进叉鞭金藻的生长，具有生产应用的前景．
Microalgae new breeding are important foods for aquatic animals in larval breeding. It is very important to seek after technology for solving the problem during algal producing. Far-infrared nanoceramics can alter the structure of water molecular clusters,which may have affected biological functions. In the test,we applied far-infrared nanoceramic materials in Dicrateria sp. tanks with the control under the same conditions. The highest algal density was 345.3 × 10^4 - 397.8 × 10^4cells/cm^3 in test groups while 293.8 × 10^4 - 323.0 × 10^4cells/cm^3 in control groups, relatively. The treated groups gained 20% higher growth rate and the incubation time to the highest density was shortened by 2 ~ 4 days. The results shows a significant difference between the treated groups and controls. It indicate that nanoceramics can promote the growth of Dicrateria sp. and can be applied in algal culture.
