金鱼微囊饲料与破碎饲料水中稳定性及金鱼幼鱼生长效果的影响

The Water Stability of Goldfish Microencapsulated Feed and Crushed Feed, and Their Impact on the Growth Performance of Juvenile Goldfish

摘要

本试验以同一基础配方制备的金鱼微囊饲料和破碎饲料为研究对象，系统比较了两种饲料在水中的稳定性差异以及对金鱼幼鱼生长性能、饲料利用率、形体指标的影响。试验使用单因素完全随机设计，将300尾初始体重为（1.52±0.12）g的金鱼幼鱼随机分成2个处理组，每组3个重复，每个重复50尾，分别投喂微囊饲料以及破碎饲料，养殖周期为56 d。结果表明微囊饲料在水中的氮溶出率、碳溶出率及质量损失率均比破碎饲料好，有着很好的水中稳定性。结果表明，微囊饲料在水中稳定性好，可以减少营养物质溶失和饲料浪费，是金鱼幼鱼养殖的优质饲料形态。

Abstract

This experiment used goldfish microencapsulated feed and crushed feed prepared with the same basal formula as research objects, and systematically compared the differences in water stability between the two feeds and their effects on growth performance, feed utilization efficiency and morphological indices of juvenile goldfish. The experiment adopted a single-factor completely randomized design, in which 300 juvenile goldfish with an initial body weight of (1.52±0.12) g were randomly divided into two treatment groups with three replicates per group and 50 fish per replicate, fed with microencapsulated feed and crushed feed respectively for a rearing period of 56 days. The results showed that the nitrogen dissolution rate, carbon dissolution rate and mass loss rate of the microencapsulated feed in water were significantly lower than those of the crushed feed, demonstrating excellent water stability. These findings indicate that the microencapsulated feed possesses good water stability and can effectively reduce nutrient leaching and feed wastage, making it a high-quality feed form suitable for juvenile goldfish culture.
