| 摘要: |
| 胶州湾是我国海洋学和水产学研究的重点海域,中国科学院海洋研究所从1980年起在胶州湾进行水产生产“农牧化”实验研究,“七五”期间进行了大水面增、养殖实验和水产资源开发技术研究;“八五”期间中国科学院组建了全国的资源、生态、环境研究网络课题(包括胶州湾),并确立了重大课题“海湾水产增殖农牧化研究”。在这些研究中,有关胶州湾内、外经济无脊椎动物资源方面积累了长达15年之久的时间序列资料,本文根据这些资料进行综合论述。重点分析了“胶州湾对虾资源补充和放流量预报硏究”1991年至1995年5月和8月试捕调査资料;胶州湾及邻近水域在“七五”期间进行的大水面增、养殖实验和水产资源开发技术研究的调査资料;山东海岸带和海洋资源综合调査及水产生产“农牧化”研究的调查资料。 |

| Abstract: |
| This paper presents results of studies on the composition and quantity dynamics of nektonic invertebrates in Jiaozhou Bay and adjacent waters using materials including 78 nektonic invertebrate species collected in May and August, 1986-1995. Mollusca 33 species, Crustacea 27 species, Echinodermata 10 species and 8 other species. The average density in August and May were 207×103 ind /k㎡ and 54×103 ind/k㎡ respectively. The maximum density (594×103ind. /k㎡)occurred in August，1990 and the minimum(24×103ind./k㎡) in May1995.The average stock biomass were 881 tons in August and 363 tons in May. The stock biomass maximum (1614 tons) occurred in August, 1990 and the minimum (56 tons)in May 1995.
The ecological features and quantity dynamics of Loligo japonica, Loligo beka,Sepiella maindroni, Sepia esculenta, Octopus ocellatus, Octopus variabilis, Portunus trituberculatus,Charybdis japonica, Oratosquilla oratoria, Metapenaeus joyneri and Trachypeneus curvirostris are described. |
