摘要:

微拟绿球藻（Nannochloropsis.sp）作为水产养殖中常用的开口饵料，其蛋白含量对于水产动物幼苗的生长发育具有重要作用。本文对N、P、Fe 3种营养盐采用正交设计的方法进行了三因素三水平的实验，测定了生物量和蛋白含量，结果表明，微拟绿球藻的生物量和蛋白含量均受到N、P、Fe 3种营养元素的影响；在设置的营养盐浓度范围内，P对生物量的影响最大，而Fe对蛋白含量的影响最大；当N、P、Fe的浓度分别为24.6、1.1和0.2 mg/L时，生物量产量和蛋白含量均达到最高。

Abstract:

Nannochloropsis sp.is commonly used as weaning feed in aquaculture, the protein content of which plays an important role in the growth and development of seedlings of aquatic animals.In this paper, three kinds of nutrients, N, P and Fe, were tested by orthogonal design methods at three levels on Nannochloropsis sp.The biomass and protein content were determined at the end of experiment.Results showed that both biomass and protein content of Nannochloropsis sp.were influenced by the levels of N, P and Fe; among the range of nutrient concentrations of this paper, P had the greatest impact on the biomass while Fe had the greatest impact on the protein content; when N, P, Fe concentrations were 24.6, 1.1 and 0.2 mg/L respectively, both the biomass yield and protein content were the highest.
