中文摘要:
      对池塘养殖暗纹东方Tun(Fugu obscurus)的一龄鱼(体重40~80g)、二龄鱼(体重200~300g)鱼体的生化组成进行了分析。结果表明:二龄鱼的粗蛋白含量低于一龄鱼,而粗脂肪含量则明显高于一龄鱼;在必需氨基酸中,二龄鱼除了赖氨酸、精氨酸含量明显高于一龄鱼外,其余氨基酸的含量几乎都低于一龄鱼,且它们的组成比例较接近,在非必需氨基酸中,一龄鱼、二龄鱼均以谷氨酸的含量为最高,分别占非必要氨基酸的26.54%和26.69%;在脂肪酸的组成上,二龄鱼的单烯酸的含量都比一龄鱼高,尤其是C18:1含量比一龄鱼高12.23,而饱和脂肪酸、多烯酸的含量则一龄鱼比二龄鱼含量高,尤其是DHA的含量比二龄鱼高4.43%;在测定的14种矿物元素中,二龄鱼的Ca、Zn的含量明显高于一龄鱼外,其余元素的含量略低于或接近一龄鱼。
英文摘要:
      The biochemical composition of one-year old ( weight: 40- 80g) and two-year old Fugu obscurus ( weight: 200- 300g ) cultured in ponds was studied. The results showed the content of crude protein of twoyear old f ish was lower than that of one-year old, but the content of crude fat is higher than that of one-year old obviously. Among essential amino acids, the level of lysine and arginine of two-year old f ish were apparently higher than that of one-year old, the contents of the other amino acids are all lower than those of one-year old, and their component rates were similar. Among non-essential amino acids, glutamic acid content is the highest in both one-year and two-year old fish, which is 26. 54% and 26. 69% respectively. The contents of monounsaturated fatty acids of two-year old fish are higher than those of one-year old, especially the C18B1which content of two-year old fish increased by 12. 23% . But the contents of saturated and highunsaturated fatty acids of one-year old f ish are higher than those of two-year old, especially the DHA which contents are 12. 86%, 8. 43% respect ively. Among the 14 measured mineral elements, the contents of Ca、Zn of two-year old f ish are obviously higher than those of one-year old, the contents of the other elements are lower than or almost close to those of one-year old f ish.
