金鱼饲料的必要成分

金鱼（细节）

现在很多人都养金鱼，特别是新手自己制作饲料或喂活饵，这是一件非常麻烦的事情。不适当地投喂活饵也会污染水质，使鱼生病。因此，人工饲料的出现可以满足金鱼爱好者在家庭中饲养和玩耍金鱼的需求。饲料需要完整的营养物质来满足金鱼生长发育的需要。接下来，我们来看看人工饲料中应该包含哪些营养成分。1.蛋白质。蛋白质是金鱼身体的主要成分。它在体内的功能是生长新组织，修复旧组织，也是供热的组成部分。诱饵中必须有足够的蛋白质来促进金鱼的快速生长。2.脂肪。脂肪是能量储存最高的食物。它的生理功能与糖相同，糖在体内氧化并提供能量。一般来说，饲料中的脂肪过多，鱼中的脂肪太多，都会阻碍性腺的发育；然而，金鱼缺乏脂肪，生长缓慢，体型较小，会降低鱼对低温和缺氧的耐受力，在越冬期间容易造成死亡。3.糖。糖是金鱼热能的主要物质，也是金鱼的主要饲料成分。它们还可以增加ATP的形成，促进氨基酸的活化，促进鱼蛋白的合成。然而，如果饲料中的糖水平超过一定限度，就会引起鱼类抗病性低、生长缓慢和死亡率高的症状。4.维生素。这也是金鱼生长所必需的。长期缺乏维生素，鱼类发育不良，生长缓慢或完全停止，甚至畸形，降低了对外部不利环境和各种鱼类疾病的抵抗力。缺乏维生素E会导致性腺发育不良或发育不足，对水生真菌的抵抗力会降低；缺乏维生素A会导致彩鳍断裂，鱼体色素消失，体色褪色不亮；在饲料中添加少量维生素B12可以促进生长。5.无机盐。它们是彩色骨的主要元素，如磷酸钙和碳酸钙。鱼的血液和肌肉也含有一定量的钙和磷。饲料中一定量的钙也能促进消化，有助于脂肪和磷的吸收。金鱼还需要铁、铜、镁、钠、钾、钻石和其他微量元素。如果没有这些元素，它会生长缓慢并导致疾病

The necessary ingredients of goldfish feed

Goldfish (details)

Many people now raise goldfish, especially novices who make their own feed or feed live bait, which is a very troublesome thing. Improper feeding of live bait can also pollute the water quality and make fish sick. Therefore, the emergence of artificial feed can meet the needs of goldfish lovers to raise and play goldfish in their families. The feed requires complete nutrients to meet the needs of goldfish growth and development. Next, let's see what nutrients should be included in the artificial feed. 1. Protein. Protein is the main component of goldfish body. Its function in the body is to grow new tissues, repair old tissues, and is also a component of heat supply. There must be enough protein in the bait to promote the rapid growth of goldfish. 2. Fat. Fat is the food with the highest energy storage. Its physiological function is the same as sugar, which oxidizes and supplies energy in the body. Generally speaking, too much fat in feed and too fat in fish will hinder the development of gonads; However, the lack of fat, the slow growth and small size of goldfish will reduce the endurance of fish to low temperature and hypoxia, and it is easy to cause death during overwintering. 3. Sugar. Sugar is the main substance of heat energy in goldfish, and is the main feed ingredient of goldfish. They can also increase the formation of ATP, facilitate the activation of amino acids and promote the synthesis of fish protein. However, if the sugar level in the feed exceeds a certain limit, it will cause the symptoms of low disease resistance, slow growth and high mortality of fish. 4. Vitamins. This is also necessary for goldfish growth. Long-term lack of vitamins, poor development of fish, slow growth or complete stop, and even malformation, reduce the resistance to external adverse environment and various fish diseases. Lack of vitamin E will lead to gonadal dysplasia or underdevelopment, and the resistance to aquatic fungi will be reduced; Lack of vitamin A will cause the fracture of color fin, the disappearance of fish body pigment, and the fading and non-bright body color; Adding a small amount of vitamin B12 in the feed can promote growth. 5. Inorganic salts. They are the main elements of color bone, such as calcium phosphate and calcium carbonate. Fish blood and muscle also contain a certain amount of calcium and phosphorus. A certain amount of calcium in the feed can also promote digestion and help the absorption of fat and phosphorus. Goldfish also need iron, copper, magnesium, sodium, potassium, diamond and other trace elements. Without these elements, it will grow slowly and cause disease
