中肋骨条藻是一种广温性、广盐性的硅藻类。它具有营养丰富,适口性好,而被广泛应用于虾类、贝类和鱼类的苗期饵料。但由于其培养难度大,且又未形成工厂化生产的规模。因此,全国沿海各水产苗种培育单位,对中肋骨条藻的需求量很大。笔者自1994年2月15日至10月25日,对中肋骨条藻工厂化培养的有关问题进行了研究。结果获得密度为90～150万个细胞/ml 的藻液2580m~3。应用在当年培育的斑节对虾、日本对虾、刀额新对虾等的苗期饵料,并取得较佳的育苗效果。现将有关培养技术简介如下。
Skeletonema costatum is a wide temperature, wide-salt diatoms. It is nutritious, palatability is good, but is widely used in shrimp, shellfish and fish seedlings. However, due to its difficulty in cultivation, it did not form the scale of industrialized production. Therefore, the national coastal aquaculture seed cultivation units, the demand for Skeleton algae is very large. The author from February 15, 1994 to October 25, the rib rib on the factory culture of the relevant issues were studied. As a result, 2580 m 3 of the algae was obtained at a density of 90-1,500,000 cells / ml. Applied in the year of culture Penaeus monodon, Japanese shrimp, Penaeus shrimp and other seedlings feed, and get better nursery results. Now about training technology is as follows.
