摘要:

检测分析成年雌性中国鲎不同组织的营养成分,探索其繁殖期的营养需求,寻找促进中国鲎性腺发育和卵细胞成熟的方法。采用国标生化分析方法对成年雌性中国鲎肌肉、黄色结缔组织和卵的常规营养、氨基酸和脂肪酸进行测定。结果表明,3种组织在常规营养成分、氨基酸和脂肪酸组成上较为一致,但在含量上存在着明显差异,肌肉水分含量最高(77.5%),卵粗蛋白含量最高(27.9%),黄色结缔组织粗脂肪(16.5%)、粗灰分(1.6%)、钙(1220 mg/kg)、磷(107 mg/100 g)含量均最高。3种组织中检测出17种氨基酸、13种脂肪酸;氨基酸组成中以谷氨酸(Glu)含量最高,脂肪酸组成中以棕榈酸(C16:0)和油酸(C18:1)含量为最高。DHA和EPA含量均为卵>黄色结缔组织>肌肉。以上结果说明,成年雌性中国鲎肌肉具有高蛋白质、低脂肪的特点,卵中含有丰富的氨基酸和不饱和脂肪酸。研究结果对于其种质资源保护、合理开发利用和营养价值评价均具有一定参考意义。

Abstract:

The nutrient compositions of different tissues of adult female tri-spine horseshoe crab Tachypleus tridentatus were determined and analyzed to explore the nutritional requirements during spawning period as well as to promote their gonadal development and egg cell maturation. The important nutrient components, including amino acids and fatty acids, of muscles, yellow connective tissues and eggs were measured using the Chinese national standard biochemical analysis methods. The results show that the compositions of common nutrients, amino acids and fatty acid, but not their levels, are similar among the tissues. The muscle tissues have the highest moisture level (77.5%), the egg crude protein content is the highest (27.9%), and the yellow connective tissues record the highest contents of crude lipid (16.5%), ash (1.6%), calcium (1220 mg/kg) and phosphorus (107 mg/100 g). There are 17 kinds of amino acids and 13 kinds of fatty acids in the three tissues, in which amino acid Glu, fatty acids palmitic acid (C16:0) and oleic acid (C18:1) are the highest. The relative contents of fatty acids DHA and EPA in the three tissues are the highest in eggs, followed by those of yellow connective tissue and muscle. These results indicate that the muscle of adult female T. tridentatus is characterized by the high protein and low lipid contents, while the eggs are rich in amino acids and unsaturated fatty acids. The findings are useful for the conservation and sustainable use of horseshoe crab stock resources, and their nutritional value evaluation.
