于 1998年 4月 5日至 6月 2 3日 ,在山东省烟台市四十里湾海区进行了 3种养殖模式养殖效果比较的模拟实验。在该海区岸边建立了栉孔扇贝 (Chlamysfarreri)单养 ,栉孔扇贝和海带 (Laminariajaponica)混养 ,栉孔扇贝、海带和刺参 (Apostichopusjaponicus)混养等 3个系列、9个养殖系统和 1个对照系统(5 .0m× 2 .0m× 1.0m ,日换水量 10 0 % ) ,进行对比实验。定期观测环境和营养盐的变化 ,栉孔扇贝、海带和刺参的存活和生长状况等。初步研究结果表明 ,扇贝单养和贝藻参混养模式栉孔扇贝的生产力分别为 :0 .5 6g/m2 ·d和 0 .78g/m2 ·d ;贝藻参混养模式刺参的生产力为 0 .70g/m2 ·d。单养栉孔扇贝生长速度比贝藻混养和贝藻参混养模式中栉孔扇贝的生长速度要慢 ,贝藻参混养的生态效益和经济效益明显高于扇贝单养和贝藻混养。如不考虑其它滤食性动物的影响 ,从测得的养殖容量可以推算 ,单养和贝藻参混养模式中栉孔扇贝养殖密度可达 2 1个 /m2 和 2 3个 /m2 。贝藻混养和贝藻参混养模式中海带适宜的养殖密度为 0 .6 8棵 /m2 和 0 .71棵 /m2 ,刺参的适宜放养密度为 2 .0个 /m2 。
From April 5 to June 23, 1998, a simulation experiment was conducted to compare the effects of three aquaculture practices in Sishili Bay, Yantai City, Shandong Province. Three families including Chlamys farreri, polyculture of Zhikong scallop and Laminaria japonica, Zhikong scallop, seaweed and Apostichopus japonicus polyculture were established on the coast of the sea. A control system (5 .0m × 2 .0m × 1.0m, daily water exchange rate of 10%), comparative experiments. Regular observations of changes in the environment and nutrients, the survival and growth of scallop, seaweed and sea cucumber, etc. Preliminary results showed that the productivity of scallop chlamys farreri and scallop algae mixed culture mode were 0.56g / m2 · d and 0.78g / m2 · d, respectively. The productivity of sea cucumber Is 0.70g / m2 · d. Chlamydomonas single culture monkshood growth rate than the mixed culture of Platycladus polyphemum and Ching Hau scallop growth mode slower, the ecological benefits and economic benefits of cabbage mixed culture was significantly higher than the scallop Monoculture and shellfish mixed support. Without considering the effects of other filter feeders, the estimated breeding capacity can be estimated that the single culture and the mixed culture mode of Chlamys farreri can reach 21 / m2 and 23 / m2. The suitable stocking density of kelp was 0.868 and 0.71 trees / m2 in seaweed polygamous and mixed seaweeds, respectively, and the suitable stocking density of sea cucumber was 2.0 / m2.
