摘　　要：为探究海湾扇贝-刺参筏式综合养殖模式的可行性,2022年5月19日—11月19日,在河北省乐亭县浪窝口和昌黎县新开口进行海湾扇贝(Argopecten irradians)-刺参(Apostichopus japonicus)筏式笼养试验。试验分为两个阶段,第一阶段用扇贝养成笼(孔径2.5 cm)外套7目(孔径3 mm左右)网袋,单养海湾扇贝和刺参苗种。海湾扇贝壳高0.5 cm左右,大规格刺参(30 ind./kg)每层5头和3头,小规格刺参(100 ind./kg)每层15头、10头和5头。2022年8月19日第二阶段海湾扇贝和刺参单、混养试验,海湾扇贝壳高2 cm左右,每层40粒左右。单养时刺参密度同第一阶段;混养时大规格刺参(20 ind./kg)每层2头和1头,小规格刺参(60 ind./kg)每层2头和3头。结果显示,刺参末体质量和特定生长率均随养殖密度的增大而减小,混养模式下大规格刺参末体质量每层2头组显著低于每层1头组(P<0.05),小规格刺参特定生长率每层5头组显著低于每层3头组(P<0.05),两海域海湾扇贝混养模式下与对照组(单养模式)间生长无显著差异(P>0.05)。本研究表明,在海湾扇贝-刺参筏式综合养殖模式下,海湾扇贝的生长不受影响,但降低刺参密度可提高刺参的个体质量和特定生长率。综上所述,海湾扇贝-刺参筏式综合养殖模式可以作为海湾扇贝规模化养殖区的有益补充。In order to explore the feasibility of the integrated culture model of bay scallop(Argopecten irradians)-sea cucumber(Apostichopus japonicus)raft,a raft cage co-culture trial of bay scallop-sea cucumber was conducted in Langwokou,Laoting County and Xinkaikou,Changli County,Hebei Province from May 19 to November 19 in 2022.The trial was divided into two phases:in the first stage,scallop grow-out cages(mesh size of 2.5 cm)coated with 7 mesh(mesh size of 3 mm)net bags,monoculture of bay scallop and sea cucumber seedlings.Bay scallops with shell height of about 0.5 cm,large sea cucumber(30 ind./kg)was farmed at density of five individuals and three individuals per layer,and small sea cucumber(100 ind./kg)at density of 15 individuals,10 individuals and five individuals per layer.In the second phase,bay scallops and sea cucumber were monoculture and polyculture trials on August 19 in 2022.The bay scallop with shell height of about 2 cm was reared at each layer of about 40 individuals.The sea cucumber was monocultured as the same density as in the first stage;In polyculture,however,large size(20 ind./kg)sea cucumber was farmed at density of two individuals and one individual per layer,and small size sea cucumber(60 ind./kg)was farmed at density of two individuals and three individuals per layer.The results showed that the sea cucumber had poor body weight and specific growth rate with the increase in culture density,with significantly lower body weight in the large-size sea cucumber with two individuals per layer than that in one individual per layer group(P<0.05)in polyculture mode,and the specific growth rate was shown to be significantly lower in five individuals per layer group than that in the three individuals per layer group(P<0.05),without significant difference between the polyculture mode and the control groups(monoculture mode)in the two seas(P>0.05).The findings indicated that the raft culture model of bay scallop and sea cucumber did not affect the growth of bay scallop,and the body weight and specific grow
