烟台四十里湾栉孔扇贝、海带和刺参负荷力的模拟测定

A modelling estimation of carrying capacities for Chlamys farreri,Laminaria japonica and Apostichopus japonicus in Sishiliwan Bay,Yantai,China

利用模拟养殖系统 ,实测了四十里湾海区对栉孔扇贝 (Chlamysfarreri)、海带 (Laminariajaponica)和刺参 (Apostichopusjaponicus)的负荷力。结果表明 ,模拟养殖系统中 ,单养和贝藻参混养系统对栉孔扇贝的负荷力分别为 184 .6和 2 0 1.7g/m2 ;混养系统对海带和刺参的负荷力分别为 10 6.8和 74 .7g/m2 。该海区对单养和贝藻参混养系统栉孔扇贝的负荷力分别为 7387.7和 80 72 .0kg/hm2 ,对海带和刺参的负荷力分别为 4 2 72 .0和 597.9kg/hm2 。

Sishiliwan Bay is located near Yantai, Shandong Province, with cultural areas of 830 hm 2 for Chlamys farreri, 460 hm 2 for Laminaria japonica and 250 hm 2 for Apostichopus japonicus. During April 5, 1998 to June 23,1998, the model cultural systems were established using 7 ponds with volume(5 m×2 m×1 m) each.Three ponds were used for monoculturing C. farreri at different stocking densities, and the other 3 ponds for polyculturing C.farreri, L.japonica and A. japonicus. The results show that the carrying capacities of the scallop monoculture system and polyculture system are 184.6 g/m 2 and 201.7 g/m 2,respectively, that for kelps in the polyculture system is 106.8 g/m 2, and for sea cucumbers is 74.7 g/m 2.Based on these results,the carrying capacities of Sishiliwan Bay for scallops were evaluated to be 7 387.7 kg/hm 2 in shellfish monoculture system and 8 072.0 kg/hm 2 in polyculture system, and 4 272.0 kg/hm 2 for kelps, 597.9 kg/hm 2 for sea cucumbers in polyculture system,respectively.
