摘要
根据１９８６～１９９５年５月和８月的拖网调查，胶州湾无脊椎动物由定居类群和季节回游类群组成。１０年里，５月总资源量波动在１１１～１０９２ｔ；８月有所增长，波动在３３７～３１５２ｔ。１９９３～１９９５年总资源量明显下降。在经济动物中，８月幼对虾资源量波动在１～６５４ｔ，梭子蟹６～１８６ｔ，无针乌贼和金乌贼１９～１５３ｔ。资源量之所以波动较大，与捕捞强度增长和人为损害幼体有关。
A continuous trawling investigation was made separately in May and August from 1986 to 1995 on the invertebrate abundance in the Jiaozhou Bay.The investigation result showed that the invertebrate group consisted of colonization species and seasonal migration species and within the decade the amount of the invertabrate resources fluctuated between 111～1092 t in May,but in August it increased by 337～3152 t among which the amount of the young shrimps fluctuated between 1～654 t,Portunus trituberculatus between 6～186 t,Sepiella maindroni sepia esculenta between 19～153 t.
