摘要:

本文旨在研究池塘养殖鲤鱼(简称池塘鲤)和稻田养殖鲤鱼(简称稻田鲤)的生物学指数和肌肉营养价值的差异。取体质量约800 g的2种养殖鲤鱼各3尾,测量和比较生物学指数并分析肌肉的常规营养成分、氨基酸和脂肪酸含量。结果显示,池塘鲤的肥满度和出肉率显著高于稻田鲤,而尾柄长/尾柄高比值以稻田鲤较高,池塘鲤肌肉中的粗脂肪、粗蛋白、粗灰分、总必需氨基酸、总非必需氨基酸、总氨基酸、总单不饱和脂肪酸含量及必需氨基酸分均显著高于稻田鲤,而总多不饱和脂肪酸、∑n-6 PUFA、总高度不饱和脂肪酸含量均以稻田鲤较高。综上,稻田鲤体型修长出肉率低,肌肉常规营养成分含量低,池塘鲤肌肉氨基酸含量高,但两者肌肉的脂肪酸组成各有优势。

Abstract:

This study aims to investigate the differences of biological indexes and meat nutrients of Cyprinus carpio from earth pond reared mode and rice field reared mode (earth pond reared is defined as ER and rice field reared as RR, respectively). Three ER and three RR carps (approximately 800 g) were collected to measure and compare the biological indexes. In addition, the contents of conventional nutrients, amino acids and fatty acids of meat were analyzed and compared between ER and RR. The results showed that the condition factor and meat yield of ER were significantly higher than those of RR, while higher caudal peduncle length/caudal peduncle depth ratio was recorded in RR. Higher contents of crude fat, crude protein, ash, total essential amino acids, total nonessential amino acids, total amino acids and total monounsaturated fatty acids, and the essential amino acid score of meat were detected in ER, while significantly higher contents of total polyunsaturated fatty acids, ∑n-6 PUFA, and total highly unsaturated fatty acids were recorded in RR. In conclusion, the RR has slender body, lower meat yield and lower conventional nutrient contents; the meat amino acids contents of ER are higher than that of RR, while the meat fatty acids composition of carps of the two modes has their own advantages, respectively.
