Moreover, according to element compositions in mussels, these fishes were divided into three groups. The first group was characteristic with low phosphorus and high C/N ratio including Engraulis japonicus, Conger myriaster and Scomberomorus niphonius. The second had low phosphorus and low C/N ratio including fishes such as lower and middle carnivores such as Pseudosciaena polyactis, Platycephalus indicus and Argyrosomus argentatus. The third included some cold temperatefishes such as Scomberomorus niphonius and Liparis tanakae that were high phosphorus and low C/N ratio.
