三角鲤几种常见天然饵料的营养分析与评价

Analyses and evaluation the nutrition of some common natural diets on Cyprinus multitaeniata pellegrin et chevey

研究从饵料营养分析入手,采用化学和生物学相结合方法,综合评价了三角鲤几种常见天然饵料的营养价值,结果表明:水蚤、水蚯蚓、野杂鱼均是三角鲤优质的饲料蛋白源及良好的能源物质;三种饵料的第一限制氨基酸同为蛋氨酸,第二限制氨基酸同为赖氨酸;三角鲤苗种培育效果比较,水蚤组显著优于水蚯蚓和野杂鱼组,而后两组间无明显差异。

Testing nutrition of diet by chemical method combined with biology method, the nutrition value of some common natural diets on Cyprinus multitaeniata pellegrin et chevey are comprehensive evaluation. The resuit demonstrated that daphnia, tubificidae and wild fishes are good of free protein sources and energetic substance to Cyprinus multitaeniata pellegrin et chevey. The first limited amino acid is methionine and the second limited amino acid is lysine in three natural diets. Comparison of breeding effects in Cyprinus multitaeniata pellegrin et chevey , the group of daphnia were better to the two group of tubificidae and wild fishes, but the group of tubificidae and wild fishes were not remarkable.
