A study was conducted with non-conventional ingredients to test their efficacy as fishmeal (FM) replacers in the diet of fringe- lipped carp. Labeo fimbriatus first feeding larvae and fry were reared for 30 and 60 days in indoor, 50 L, aerated, circular plastic tanks at 100 and 30 numbers tank⁻¹, respectively. In the first feeding larvae to fry rearing experiment (Exp. 1), the fish were fed with either of the following isonitrogenous and isocaloric diets – live plankton, FM diet, green bottle fly (Lucilia sericata) larvae meal (GBFLM) diet and silkworm pupa (SWP) diet. The fry to fingerling rearing (Exp. 2), was also conducted using the same diets described above except live plankton. All compounded diets were formulated to contain 40% crude protein for the experiment 1 and 35% for experiment 2 and were fed ad libitum. Triplicate tanks were maintained for each treatment in both the experiments. In Exp. 1, the mean final weight of fry was higher with plankton and FM diets, while no difference (p > .05) was observed between FM and GBFLM diets. Weight of fish fed SWP diets was not statistically different from those fed GBFLM diet. No difference (p > .05) in final length, survival and condition factor was recorded. Analysis of digestive enzyme activity of whole fish revealed lower (p < .05) activity of amylase in fish fed plankton. In Exp. 2, no difference (p > .05) was observed between the different diet groups in terms of mean final weight, length, survival and condition factor. Analysis of digestive enzyme activity of whole fish revealed no difference (p > .05) in the activity of digestive enzymes between the treatments except a lower (p < .05) activity of trypsin in FM diet and lipase in FM and GBFLM diets. Since the survival and condition factors of animals is the most important aspect during nursery rearing, similar (p > .05) values recorded in different treatments indicate the possibility of incorporation of these non-conventional protein sources in the diet of L. fimbriatus during first feeding larvae to fry and fry to fingerling rearing.

用低成本日粮培育流唇鲤、Labeo fimbriatus (Bloch) 的幼体，包括绿瓶蝇 Lucilia sericata (Meigen) 幼虫粉混合日粮

使用非常规成分进行了一项研究，以测试它们作为鱼粉 (FM) 替代品在流唇鲤鱼饲料中的功效。Labeo fimbriatus首先饲养的幼虫和鱼苗分别在 100 和 30 号罐^{-1 的}室内 50 升充气圆形塑料罐中饲养 30 天和 60 天。在第一次饲喂幼虫进行鱼苗饲养实验（实验 1）中，鱼被饲喂以下任何一种等氮和等热量的饮食——活浮游生物、FM 饮食、绿瓶蝇（Lucilia sericata）) 幼虫粉 (GBFLM) 饮食和蚕蛹 (SWP) 饮食。除了活浮游生物外，还使用上述相同的饲料进行鱼苗到鱼种饲养（实验 2）。将所有复合日粮配制成含有 40% 的实验 1 和 35% 的实验 2 的粗蛋白，并随意饲喂。在两个实验中，每个处理都保持三次重复的水箱。在 Exp. 如图 1 所示，浮游生物和 FM 饮食的鱼苗最终平均重量更高，而 FM 和 GBFLM 饮食之间没有观察到差异 ( p > .05)。喂食 SWP 饮食的鱼的重量与喂食 GBFLM 饮食的鱼的重量没有统计学差异。 记录的最终长度、存活率和状况因素没有差异 ( p > .05)。全鱼消化酶活性分析显示较低（p < .05) 鱼类喂养的浮游生物中淀粉酶的活性。在 Exp. 2， 不同饮食组之间在平均最终体重、长度、存活率和状况因素方面没有观察到差异 ( p > .05)。全鱼消化酶活性分析表明， 除了 FM 饮食中胰蛋白酶和 FM 和 GBFLM 饮食中脂肪酶的活性较低 ( p < .05)外，处理之间消化酶活性没有差异 ( p > .05) 。由于动物的存活和状况因素是育苗过程中最重要的方面 ，不同处理中记录的相似 ( p > .05) 值表明这些非常规蛋白质来源有可能在L的饮食中加入。fimbriatus在第一次喂食幼虫时进行鱼苗和鱼苗养殖。
