    摘要:

    目的 初步探讨过渡期诸氏鲻虾虎鱼的营养需求,为专用配合饲料的开发及相关标准的制定提供数据参考。方法 分别采用卤虫无节幼体(Arternia nauplii, CK)和7种商业化配合饲料 (P30L8,P35L8,P50L8,P55L8;P50L12,P53L12,P55L12) 饲喂过渡期虾虎鱼幼鱼,8周生长实验以测定存活率(survival rate,SR)、增重率(weight gain, WG)、特定生长率(specific growth rate, SGR)和摄食率(feeding rate, FR)、饲料系数(feed conversion ratio, FCR) 等生长指标,并测定不同营养水平下虾虎鱼全鱼(除去内脏)的基本组份。结果 SR饲料组SR (51.78±8.98~68.22±4.95) 较对照组CK (58.22±6.51) 均无显著差异(P > 0.05);WG除P30L8 (130.76±23.67)、P50L12组 (220.86±16.9) 外,各实验组均优于对照组CK (206±41.91, P < 0.05),且饲料粗脂肪含量相同(8%,12%;能量值相差不大)时,WG随饲料粗蛋白含量的升高而上升; SGR在粗脂肪含量相同时SGR也随饲料粗蛋白含量的升高而上升;FR,FCR P50L8,P55L8;P50L12,P53L12,P55L12组均优于对照组CK (1.74±0.36),且饲料粗脂肪含量8%时随粗蛋白含量上升而下降。此外虾虎鱼鱼体基本组份均与饲料中粗蛋白、粗脂肪含量关系不大 (P < 0.05)。结论 配合饲料饲替代生物饵料是可行的,且能取得较好的生长效果;饲料粗蛋白、粗脂肪含量对虾虎鱼鱼体基本组份影响不显著 (P < 0.05);饲料粗蛋白50%,粗脂肪8%时,饲料利用率最好且过渡期虾虎鱼可获得较好的生长效果。

    Abstract:

    Objective To preliminary study nutrition requirement of Mugilogobius chulae in the transitional period and provide reference data for the research and development of compound feed and relevant standards. Methods Artemia (Artemia nauplii, CK) and 7 commercial compound feeds (P30L8, P35L8, P50L8, P55L8; P50L12, P53L12, P55L12) were used to feed goby in transitional period. At the end of 8 weeks growing experiment, some data like survival rate (SR), weight gain (WG) and specific growth rate (SGR) and so on were measured. While, 8 groups' body compositions were also measured. Results SR Treatment groups (51.78±8.98~68.22±4.95) and CK (58.22±6.51) have no significant different (P > 0.05). WG Treatment groups except P30L8 (130.76±23.67) and P50L12 (220.86±16.9) were significant larger than CK (206±41.91, P < 0.05). Using equal lipid (8% and 12%) dietary, WG increased with protein level rising.SGR Treatment groups' SGR also increased with protein levels rised.FR, FCR P50L8, P55L8; P50L12, P53L12, P55L12's FR and FCR were better than group CK (P < 0.05). Using equal lipid (8%) dietary, FR and FCR were decreased with protein level rised. In addition, different feed feeding group's body composition showed no significant difference (P < 0.05). Conclusions Rear goby with compound feed replace the living food was viable and supported appreciable growth. Their crude protein and lipid have no effect to the goby's body composition (P < 0.05). Dietary with crude protein 50% and crude lipid 8% could obtain a better growth in transitional period.
