摘要
为探明刺参Apostichopus japonicus养殖池塘混养日本囊对虾Penaeus japonicus的适宜搭配比例,通过在刺参养殖池塘围隔中进行日本囊对虾生态混养试验,比较了不同密度搭配比例下刺参(10、15 ind./m^2,湿体质量为6.05 g±3.15 g)与日本囊对虾(0、2、4、8 ind./m^2,湿体质量为0.89 g±0.36 g)的养殖效果。结果表明:经过4个多月的混养试验,刺参生长状况与混养日本囊对虾的密度大小无显著相关性,混养日本囊对虾对主养品种刺参的生长无显著性影响(P>0.05);日本囊对虾的生长主要受自身养殖密度的影响,其密度越小,存活率越高,生长速度越快;与刺参混养的两个2 ind./m^2对虾密度组最终体质量(33.90、32.47 g),显著高于4 ind./m^2对虾密度组(25.48、25.16 g)和8 ind./m^2对虾密度组(20.29、21.63 g)(P<0.05)。研究表明,综合分析产量与经济效益时,刺参搭配混养4 ind./m^2密度组的日本囊对虾经济效益最高,本研究结果可为参虾池塘生态混养模式的推广应用提供参考依据。
The sea cucumber Apostichopus japonicus with initial body weight of （6.05±3.15）g were reared in 24 enclosures of each 5 m×5 m×3 m disposed in a 400 000 m2 earthen pond with a depth of 1.5-3.5 m at stocking densi- ty of 10 and 15 individuals/m2 and co-cultured with kuruma shrimp Penaeus japonicus with body weight of （0.89± 0.36） g at stocking density of 0, 2, 4, and 8 individuals/m2 for 4 months to probe into the optimal ratio of sea cu- cumber to kuruma shrimp in their co-culture in a pond. The results showed that there was no significant relationship between growth and survival of sea cucumber and stocking density of kuruma shrimp （P〉0.05） , without significant effect of kuruma shrimp on growth of the principal sea cucumber（P〉0.05）. The growth of kuruma shrimp was af- fected by itself density, being related inversely with shrimp density. The shrimp at density 2 ind./m2 had final body weight of 33.90 g at 10 individual sea eueumber/m2, and 32.47 g at 15 individual sea eueumber/m2, significantly higher at 4 individual shrimp/m2 （ 25.48 and 25.16 g） and at 8 individual shrimp/m2 （ 20.29 and 21.63 g） （ P 〈 0.05）. The maximal profits based on survival, yieht and price was observed in the polyeulture of sea cucumber at stocking density of 4 ind./m2 with kuruma shrimp. The findings provide referenees for commercial co-culture of sea cucumber with different shrimp species in an integrated multi-trophie aquaculture system.
