东山湾贝类养殖容量的估算

以初级生产力为基础，应用营养动态模式和沿岸海域能流分析模型，估算东山湾贝类年生产量分别为269331t和295767t，平均282549t。扣除潮间带、潮下带和吊养区浮筏、随着基及延绳上附着的非养殖滤食性附着动物自然现存量35760t，贝类可养殖量为246789t。应用统计分析和逻辑斯谛种群增长模型估计贝类可养面积为11839hm^2，其中缢蛏635hm^2，石蛎1160hm^2,吊蛎1525hm^2，翡翠贻贝633hm^2，菲律宾蛤仔1154hm^2，扇贝698hm^2，江瑶248hm^2，泥蚶601hm^2，巴非蛤4151hm^2，凸壳肌蛤1034hm^2。1998年实际养殖面积和养殖产量分别为10581hm^2和220564t。尚有1258hm^2,26225t的扩大开发潜力。文中还讨论了合理布局和优化养殖结构问题。

Estimation of carrying capacity for shellfish culture in Dongshan Bay

Based on the investigation of the primary productivity,the carrying capacity of Dong shan Bay for the culture of shellfish is estimated by the nutrition bynamic model and the coast enery flow analysis method.The result shows that the annual carrying capacity is 269 331t and 295 767t , respectively,the mean value is 282 549t.The optional capacity of shellfish culture is 246 789t,not including 35 760t.of filter feeder naturally living in tidal zone, shallow sea or fouling on floating raft,fouling material and long line in the hanging culture range. The optimal area of shellfish culture calculated through statistical analysis and logical stock growing model is 11 839hm 2 ,of which the area for Sinonovacula constricta is 635hm 2,oyster growing on stone is 1 160hm 2 , oyster of hanging culture is 1 525hm 2, Perna viridis is 633hm 2. Ruditapes pholippinarum is 1 154hm 2, Chlymys nobilis is 698hm 2, Atrina pectinata is 248hm 2, Tegillarca granosa is 601hm 2. Paphia undulata is 4 151hm 2. Musculista senhausia is 1 034hm 2. The actual culture area and farming output in 1998 were 10 581hm 2 and 220 564t respectively.There is still an area of 1 258hm 2 to be exploited and 26 225t of shellfish will be yielded potentially. The reasonable arrangement and optimization of culture structure are also discussed in this paper.
