Abstract
Dried or defatted black soldier fly (Hermetia illucens) larvae meal has been shown an important ingredient in aquafeed, but little information is available about the effects of black soldier fly pulp (BSFP) on growth and health of fish. A 62-day feeding trial was conducted to assess the effects of dietary BSFP on growth performance, whole body composition, serum metabolites, antioxidant and immune response of Micropterus salmoides. Four isoproteic and isolipidic diets were formulated by adding BSFP (original substance) to the basal diet at the rate of 0% (BSFP0), 1% (BSFP1), 2% (BSFP2) and 4% (BSFP4), corresponding to inclusion of 0, 4.5, 9.0 and 18.0 g/kg DM in diets. Each diet was randomly assigned to triplicate groups of 35 fish per tank. Fish were fed twice daily to apparent satiation. Blood samples were collected at the terminal trial to analyse serum metabolites, antioxidant and immune enzyme activities. Results indicated that fish fed BSFP2 had higher (P<0.05) weight gain rate, specific growth rate and intraperitoneal fat ratio than those of fish fed other diets. Crude lipid, ash and calcium contents were higher (P<0.05) in BSFP2 than those in BSFP0. Fish fed BSFP2 and BSFP4 had lower (P<0.05) serum malonaldehyde but higher (P<0.05) acid phosphatase than other diets. It was concluded that dietary inclusion of BSFP improved growth performance of M. salmoides might be attributed to increased lipid and ash deposition. BSFP improved antioxidant and immune capacity but also increased intraperitoneal fat deposition of fish, suggesting BSFP should be careful to be used in M. salmoides diets.
摘要
干燥或脱脂的黑水虻(Hermetia illucens)幼虫饲料已被证明是水产饲料的重要原料，但黑水虻虫浆(BSFP)对鱼类生长和健康的影响的研究较少。本试验采用62d的饲养试验，研究饲料中添加BSFP对大口黑鲈生长性能、机体成分、血清代谢物、抗氧化和免疫性能的影响。在基础饲粮中添加BSFP(原物质)，分别按0% (BSFP0)、1% (BSFP1)、2% (BSFP2)和4% (BSFP4)的比例配制4种等蛋白等脂饲粮，分别对应饲粮中的添加量为0、4.5、9.0和18.0 g/kg。每种饲料随机三组，每组35条鱼。每天喂食两次，直至明显饱足。在结束试验时采集血液样本，分析血清代谢物、抗氧化和免疫相关酶活性。结果表明，投喂BSFP2的鱼增重率、特定生长率和腹腔脂肪比均高于投喂其他饲料的鱼(P<0.05)。BSFP2的粗脂肪、粗灰分和钙含量均高于BSFP0 (P<0.05)。与其他饲料相比，BSFP2和BSFP4的血清丙二醛含量较低(P<0.05)，酸性磷酸酶含量较高(P<0.05)。由此可见，在饲料中添加BSFP可能是由于增加了脂肪和灰分沉积，从而提高了大口黑鲈的生长性能。BSFP提高了鱼的抗氧化性能和免疫性能，但也增加了腹膜内脂肪沉积，提示BSFP应谨慎使用在大口黑鲈的饲料中。
