中文摘要:
      本文应用光密度对数,计算培养浮游植物的相对生长常数,并换算成繁殖间隔,连同培养繁殖高峰期的累计温度、生物密度,生物量作为培养结果的参数。浮游植物在四种不同的培养液中培养,根据所得培养参数的最优值,为各种浮游植物选配了合适的培养液。对在同种培养液中培养所收获的各种藻类的干样,进行氨基酸含量定性定量测定和营养价比较分析,结合浮游植物用于长毛对虾育苗的饵料效果,筛选出我国当前较优质的植物性活饵料种类。最后用斜面低温暗保种的办法,使得若干藻种能保存一年。
英文摘要:
      1 .In the culture of phytoplanktons the accumulative temperature at the climate of multipicatian, the relative growth constant, the generative interval, the biologial density at the climax and the biomass may be used as raising parameters. Among them, the relative growth constant has been calculated through the logarithum of the optical density.2, Tie solutions for raising phytoplankton were chosen from the best value of the raising parameter, Skeletonema castatum, Chaetoceros muelleri and Chaetoceros simptex var, calcitrans would be raised in the imitation f/2 solution. Carteria sp.would be raised in the solution of prescription No. 1. And Dicrateria zhajiangensis,Heteroloea sp.,Cryptomanas sp.,Chlamydomonas sp, and Platymonas suhcordiformis would be raised in th. solution. of prescription No. 2. The imitation f/2 solution can also be used for reserving some phytoplanktons.3. The amino--acid content of the phytoplankton and the dried flesh of Penaeus prnicillatus are as follow: Nitxschia closterium f. minutssiitima 34.6%,Chaetoreros simplex var. calcitrans 27.0%,Phaeodactylum triconutum 25.9%,Platymonas subcordiformis 22,9 %,Chlorella sp. 21.4%,Heterogloea sp. 20.0%,Dunadiella salina. 19.6%, Skeletonema costatum 18.3%,Dicrateria zhanjiangensis 10.5%,and Penaeus penicillatus 60.9%. The nutritive value of the phytaplanliton is lower than the dried flesh of the prawn. But Skeletonema costatum, Dicrateria zhanjiangensis, Heterogloea sp., Dunadiella salina.and Chlorella sp. contains methi-onine, which was absent in the dried flesh of the prawn, and Nitzschia closterium f,minutissima, Phaeodactylum triconutum , Chaetoreros simplex var, calcitrans,Platymonas subcordiformis and Skeletonema costatum are rich with lysine.4.By analysing the nutritive palue of the phytoplankton and the practical affect in rearing fry of the prawn, it is found that Nitzschia closterium. f. minutrissima,Phaeodactylum tricornutum, Skeletonema costatum,Chaetoceros simplex var.calcitr-ans and Platymonas subcordiformis are excellent foodstuffs in aquaculture.5.In spring a double concentration of the imitation f/2 solution is used for cultivation, and kept at the temperature under 10℃ . The phytoplankton of the species Dicrateria zhanjiangensis, Heterogloea sp.,Chlamydomonas sp.,Platymonas subcordiformis, Dunaliella salina.,Chlorella sp.,Nitzschia closterium f. minutrissima,and Phaeodactylum tricornutum can be reserved a year.
