[Present utilization situation of main fishery resources in Zhoushan fishing ground].
Based on principal component analysis, the present utilization situation of main fishery resources in Zhoushan fishing ground were studied. The results showed that the nine main fishery resources in Zhoushan Fishing Ground could be divided into four categories, i.e., Pseudosciaena crocea and Sepiella maindroni rochebrune were at the degenerating stage; Trichiurus haumela, Pneumatophorus japonicus and Decapterus maruadsi at the fully-utilized stage; Muraenesox cinereus, Pseudosciaena polyactis and Pampus at the partly-used stage and shrimps and crabs were at the initially-used stage. Therefore, it will be of key importance for the sustainability of fishery resources to utilize the current fishery resources at a reasonable way.
