摘要: |
于1991年6月-1992年12月对青岛文昌鱼进行室内培育研究。结果表明:1.沙是青岛文昌鱼幼虫生长发育必需的,但在实验室条件下,细沙比全沙和粗沙更有利于其生存。2.就单胞藻而言,等鞭金藻是青岛文昌鱼幼虫生长和变态较理想的饵料。 |

Abstract: |
The amphioxus B. beleheri tsingtauense were cultured from fertilized eggs in laboratory from June 1991 to Dec. 1992. The results were as follows (1) Sand was necessary for the survival of the amphioxus larvae. The larva-cultured on fine sands (filtered through a 40 μm mesh nyion net) survived longer than those cultured on coarse, or coarse-and-fine sands. (2) The larva fed (104 cells/ml) the one-celled alga Isochrysis galbana surrived longer than those fed Cyanohyceas sp., Chlorella sp., or Cyanohyceas sp. plus Chlorellas sp. and also metamor phosed. |
