Amino Acids Transmites In The Food Chain Of Key Species Within The Yellow Sea And East China Seaecosystems Food Net

This paper based on the project of the National Natural Science Foundation-the elements stable isotope studies of the marine food web nutrition dynamics and the development and planning project of the state's key basic research-the Yellow Sea and East china sea, ecosystem dynamics and sustainable use of biological resources.The major issues of the recent international IMBC indicate that molecular biology has become the forefront of marine biotechnology research field. Our marine biotechnology development urgently need to address the innovation-based research tools and contents: Controlled ecological experiments with the combination of indoor experiments, carrying out key species life history, experimenting ecological experiments ,measuring the value of the main types of resources and energy gainings, etc. Food web study simplified is a new topic to effectively understand marine ecosystems.The paper adopts controlled ecological experiments with the combination of indoor experiments and applies molecular biology techniques for simulation study in the key line of the food chain of "Chlorella spp—Calanus sinicus—Engraulis japonicus".The experiment studies both how amino acid transmissions in the key species of the food chain and the impact to amino acid composition and content when bait materials change.The report about similar study has not been seen at home and abroad.It is an innovative study to culture Engraulis japonicus indoor, at home there is not a previous example presently.We make use of Calanus sinicus for bait in culture experiment to better simulate the main line of the food chain in the Yellow Sea and East china sea and carry out our simulation study in the key line of the food chain of "Chlorella spp→Calanus sinicus→Engraulis japonicus".
