This study aimed to investigate nutrition in climbing perch which is an important nutritious economic freshwater fish in Asia and compare with (crucian carp). Three kinds of tissues, including muscle, livers, and eggs, were isolated, respectively. Physicochemical properties including moisture, ash, protein, amino acids, fat, vitamins, and calcium contents in those tissues were determined. The results showed climbing perch muscle and liver contained less moisture, but more protein, amino acids, and vitamins than crucian carp muscle and liver. While moisture, ash, protein, and total amino acids contents of climbing perch egg were lower than those of crucian carp egg. Climbing perch egg had more fat, vitamins, and calcium than crucian carp egg. The amino acid profile was also performed, and 16 amino acids were identified and quantified in muscle, liver, and egg. Among tissues, the highest and lowest concentration of total amino acid content was found in crucian carp eggs and livers, respectively. Glutamic acid (Glu) and histidine (His) were the most and least amino acids in climbing perch and crucian carp tissues, respectively. Sixteen amino acids in climbing perch egg were less than those in crucian carp egg while it is an opposite case in muscle and liver, which amino acids of climbing perch tissues were more than those of crucian carp muscle and liver. Vitamin A of climbing perch was more than crucian carp in all three tissues, but vitamin E content in climbing perch liver was lower than that of crucian carp liver. Calcium content of muscle had no difference between two species. The abovementioned comparison of physicochemical properties of different tissues from China climbing perch and crucian carp will provide a necessary supplementary of freshwater muscle nutrition research, also was helpful for application of climbing perch.
本研究旨在调查亚洲一种重要的营养丰富的经济淡水鱼——攀鲈的营养状况，并与鲫鱼进行比较。分别分离出肌肉、肝脏和鱼卵三种组织。测定了这些组织中的水分、灰分、蛋白质、氨基酸、脂肪、维生素和钙含量等理化性质。结果表明，攀鲈的肌肉和肝脏水分含量较低，但蛋白质、氨基酸和维生素含量高于鲫鱼的肌肉和肝脏。而攀鲈鱼卵的水分、灰分、蛋白质和总氨基酸含量低于鲫鱼鱼卵。攀鲈鱼卵的脂肪、维生素和钙含量高于鲫鱼鱼卵。还进行了氨基酸谱分析，在肌肉、肝脏和鱼卵中鉴定并定量了16种氨基酸。在各组织中，总氨基酸含量最高和最低的分别是鲫鱼鱼卵和肝脏。谷氨酸（Glu）和组氨酸（His）分别是攀鲈和鲫鱼组织中含量最多和最少的氨基酸。攀鲈鱼卵中的16种氨基酸少于鲫鱼鱼卵，而在肌肉和肝脏中情况相反，攀鲈组织中的氨基酸多于鲫鱼的肌肉和肝脏。在所有三种组织中，攀鲈的维生素A含量均高于鲫鱼，但攀鲈肝脏中的维生素E含量低于鲫鱼肝脏。两种鱼肌肉中的钙含量没有差异。上述对中国攀鲈和鲫鱼不同组织理化性质的比较将为淡水鱼类营养研究提供必要补充，也有助于攀鲈的应用。
