单一或二元的凡纳滨对虾新鲜养殖废物用于花刺参养殖的研究

Sole and binary fresh waste from shrimp (Litopenaeus vannamei) for culture of sea cucumber (Stichopus monotuberculatus)

  • 摘要: 评估了单一或二元的新鲜凡纳滨对虾(Litopenaeus vannamei)养殖废物用于花刺参(Stichopus monotuberculatus)养殖的可行性,并研究了其对花刺参成活率、特定生长率、排粪率、排氨氮、排亚硝酸盐、粪便中总有机物(TOM)质量分数相比对应的饲料中总有机物质量分数变化的影响。摄食含80%露天养虾废物和20%室内养虾废物的饲料的花刺参生长最快。在同一处理组中,花刺参的夜间排粪率显著高于昼间排粪率(P0.05)。花刺参最高和最低的平均总排粪率分别出现在E(20%露天养虾废物和80%室内养虾废物) 和A(露天养虾废物) 处理组。随着不同饲料中粗蛋白水平的降低,花刺参的平均氨氮生产量和亚硝酸盐生产量逐渐降低。随着不同饲料中w(TOM)的降低,不同处理组花刺参排出的粪便中w(TOM)先升高后降低。在每一个处理组中,花刺参排出的粪便中w(TOM)与对应的饲料中w(TOM)相比,都有不同程度的降低,显示花刺参具有降低养虾废物有机污染的潜能。

     

    Abstract: Weassessed the feasibility of using sole and binary fresh waste from shrimp (Litopenaeus vannamei) for the culture of sea cucumber (Stichopus monotuberculatus) by studying the effects of sole and binary shrimp waste on sea cucumber's survival rate, specific growth rate (SGR), fecal production rate (FPR), ammonia-nitrogen and nitrite-nitrogen productionsas well asthe variations of total organic matter (TOM) content in the feces comparing with thosein corresponding feeds. Sea cucumbers grew fastest when fed with a diet containing 20% outdoor shrimp waste and 80% indoor shrimp waste. In the same diet treatment, FPR in the nighttime was significantly higher thanin the daytime (P0.05). The highest and lowest average total FPR occurred in diet treatment E(80% outdoor shrimp waste and 20% indoor shrimp waste) and diet trement A(outdoor shrimp waste), respectively. Both the ammonia-nitrogen production and nitrite-nitrogen production of sea cucumbers in different diet treatments decreased gradually as the crude protein levels in different diets decreased.TOM content in each feeds decreased while that in the feces increased at first, and then decreased gradually, respectively. In each diet treatment, the TOM content in feces decreased to different extent compared with those in the corresponding feeds, indicating sea cucumber has the crude potential of reducing organic pollution of shrimp waste.
