The analysis methods for the determination of micro or trace elements in high moisture jellyfish were developed. The fatty acid compositions in difderent parts of fresh jellyfish were determined by GC/MS method. Thirty-five fatty acids were identified, and most of them were found in R. esculentum jellyfish for the first time. Especially, two unusual very long chain polyunsaturated fatty acids that were never detected in the other jellyfish also were determined. Amino acids were abundant in R. esculentum jellyfish, especially containing sulfur amino acids, and could be supplied for human diet. The polysaccharide in umbrella part of jellyfish was composed of glucose, galactose and uronic acid, and its molecular weight was 40,000, but the polysaccharide of the oral arms part consisted of glucose, mannose and glycuronic acid, and its molecular weight was 43,000. Above-mentioned data were never reported. The ethanolic extract of oral arms part of jellyfish were extracted by different polar solvents (petroleum ether, acetic ether, n-butanol), and antibacterial activity was tested to these extracts by four species of terricolous pathogenic bacilli and three species of botanic pathogenic fungi. The result demonstrated that the petroleum ether extract had certain bactericidal activity for two species of pathogenic bacilli, and n-butanol extract had certain inhibited activity on apple rot pathogenic fungus.

The synthetic nourishment index method averages the trophic index of all parameters, and then evaluates the degree of the eutrophication. The total composition analysis nourishment evaluation colligates all kinds of representative parameters, and then evaluates the degree of the eutrophication. The grey system theory method evaluates the degree of the eutrophication through a series of calculations, such as constructing situation and situation matrix, confirming object degree, and so on.

总成分分析营养度评价法是通过对各单因子的分营养度进行算术平均，将水体营养状态连续分级；综合营养状态法是综合多项富营养化代表性指标，将其表示成指数，对水体营养状态连续乡级；灰色系统理论法是通过构造局势与局势矩阵、确定目标效果测度、多目标决策、确定最优局势等一系列系统分析计算，判断水体富营养化级别。
