中文摘要:凡纳滨对虾幼虾时期,主要食物种类组成存在一个转化时期。以碳稳定同位素做示踪元素对幼虾食物组成中浮游生物和配合饲料比例变化进行研究,分析高位池对虾养殖早期其食物组成的变化规律。结果发现,浮游生物和配合饲料的碳同位素值分别为-20.03(±0.51)‰、-22.54(±0.62)‰。对虾虾苗在高位池内养殖第1、10、17、24、30、37 d时,肌肉的碳同位素值分别为-19.23(±0.25)‰、-19.01(±0.22)‰、-19.25(±1.06)‰、-19.45(±0.92)‰、-20.12(±0.07)‰、-20.04(±0.10)‰。浮游生物在食物组成中的比例分别为67.7(±0.10)%、77.0(±0.10)%、67.0(±0.42)%、68.0(±0.24)%、51.7(±0.32)%、36.0(±0.10)%;配合饲料所占比例为32.3(±0.10)%、23.0(±0.10)%、33.0(±0.42)%、32.0(±0.24)%、48.3(±0.32)%、64.0(±0.10)%。浮游生物在食物组成中的比例与体长和体重间的关系方程分别为y=-0.19x2+3.47x+55.05(R2=0.94)、y=-0.0007x2-0.12x+71.88(R2=0.94),配合饲料在食物组成中的比例与体长和体重间的关系方程分别为y=0.19x2-3.47x+44.95(R2=0.94)、y=0.0007x2+0.12x+28.12(R2=0.94)。结果表明,凡纳滨对虾在体长19.44(±3.63)~23.20(±0.10)mm和体重105.07(±5.39)~160.49(±0.10)mg范围时,食性发生转化,其主要食物组成由以浮游生物饵料为主转向以配合饲料为主。
外文摘要:There is a conversation of diet for juvenile Litopenaeus vannamei. The proportion of plankton and artificial feed in food composition of juvenile shrimp was analyzed for the regular pattern of diet using carbon stable isotope as tracer element. The results showed that carbon isotope value of plankton and artificial feed were -20.03(±0.51)‰, -22.54(±0.62)‰, respectively. After shrimp seed were cultured in pond for 1, 10, 17, 24, 30, 37 days, the carbon isotope value of muscle in juvenile shrimp were -19.23(±0.25)‰, -19.01 (±0.22) ‰, -19.25 (±1.06) ‰, -19.45 (±0.92) ‰, -20.12 (±0.07) ‰, -20.04 (±0.10)‰, respectively, the proportion of plankton in food composition were 67.7(±0.10)%, 77.0(±0.10)%, 67.0(±0.42)%, 68.0(±0.24)%, 51.7(-±0.32)%, 36.0(-±0.10)%, respectively, the proportion of artificial feed were 32.3(-±0.10)%, 23.0(-±0.10)%, 33.0(±0.42)%, 32.0(±0.24)%, 48.3(±0.32)%, 64.0(±0.10)%, respectively. Equations between proportion of plankton and length, weight were y=-0.19x2±3.47x±55.05 (R2=0.94), y=-0.0007x2-0.12x±71.88 (R2=0.94), respectively, equations for artificial feed were y=0.19x2-3.47x±44.95 (R2=0.94), y=0.0007xE+0.12x+28.12 (R2=0.94), respectively. The result indicated that the diet conversation was occurred when the length was at the range of 19.44 (±3.63)-23.20 (±0.10) mm, the weight was at the range of 105.07(±5.39)-160.49(±0.10) mg, and the main food of juvenile shrimp changed from plankton to artificial feed.
