夏季金鱼养殖的四个要点

金鱼（细节）准备在夏季钓鱼的朋友们要注意，夏季来临时，天气炎热，水温也随之升高。如果不采取相应的措施，极易造成饲养水中缺氧，或产生有害物质，这会导致金鱼“中暑”或中毒，不仅会影响金鱼的观赏效果，还会导致死亡。金鱼养殖注意事项：1。鱼缸的准备：在选择的时候，要选择自己喜欢的形状，并且要符合家居环境。气缸壁应清晰、透明、光滑、无瑕疵。一般来说，在买鱼之前3到4天，把鱼放进去，放上鹅卵石和其他底石，然后用干净的水装满。它一方面可以使水体成熟，另一方面可以让水藻在缸壁上生长，这对金鱼的生长是有利的。2、 金鱼的选择：在良好条件下养殖的金鱼：如果金鱼的水体浑浊，水中有大量污垢，培养容器（水槽）的壁是模糊的，大多数金鱼漂浮在水面上，头部一个接一个地漂浮，这意味着该地的经营者管理不善，养殖条件较差，而这里的金鱼可能有内伤和体质差，最好不要选择，否则，养殖的成活率也会下降。选择健康无害的金鱼：健康的金鱼具有鲜艳的体色、完整的鳞片和鳍、对称的眼睛等特征。仔细观察鱼体，体表无白斑、无霉变等污染物。在清澈的水中，它会在靠近底石的时候寻找食物，而不是独自游泳。然后将这些金鱼放入另一个容器中观察，并选择你喜欢的个体。身体摩擦四壁的金鱼可能会在体表出现轮虫等皮肤病，这通常很难用肉眼看到，也应该被去除。选择形状漂亮的金鱼：金鱼有许多形状和不同的品种。体型一般可分为三种：侧扁、扁圆和中间。侧扁具有普通鲫鱼的体型；背部平坦弯曲；中间类型介于两者之间。顶级金鱼应该有短而圆的身体、对称的鳍、整齐的鳞片和明显的物种特征。同时，鱼的颜色要纯正，不乱，身体要平衡，泳姿要柔和，动作要跳舞。此外，为了增加观赏价值，同时购买的金鱼应该有不同的颜色和形状。3、 金鱼的运送：1。金鱼的装运：购买的金鱼一般用塑料袋装水装运，离家较远时应装满氧气。长途运输后，它们可以装进纸箱。他们被要求在第一天不要喂金鱼，在运输过程中也不要放水草，以防止腐烂和水质恶化。2、金鱼的摆放：运来的金鱼不应立即放入鱼缸，而应采用“缓苗”处理，以保持水温基本不变。方法是将装有鱼的塑料袋与水和鱼一起放在鱼缸中约20分钟，然后慢慢倒出金鱼，使其进入鱼缸。一般直径30厘米左右的鱼缸可以放2-3条体长3厘米的金鱼，在炎热的夏天可以减少到1-2条。较大的也可酌情减少。4、 金鱼饲养注意事项：金鱼是冷血动物，体温随水温变化。因此，金鱼在夏季应注意以下几点：水温不宜过高。温度低于30℃为宜。水族馆外面应该覆盖有遮阳物，如竹帘。温差不应太大。换水时，如果水温差超过4℃~5℃，金鱼神经会受到刺激，导致金鱼停滞、停止进食或生病。如果水温过高，立即缓慢注入冷水以降低水温。不要喂得太多。最好每天早上喂它一次，前提是你能吃完。你不能喂它太多，否则金鱼会因贪食而死。鱼缸里的旧水应该经常更换。每天下午或晚上应更换水箱中三分之一的旧水，并清除水箱底部的鱼粪和食物残渣

Four key points of goldfish breeding in summer

Goldfish (details) Friends who are preparing to fish in summer should pay attention to the fact that when summer comes, the weather is hot, and the water temperature rises with it. If no corresponding measures are taken, it is very easy to cause hypoxia in the feeding water, or produce harmful substances, which will lead to "heatstroke" or poisoning of goldfish, which will not only affect the viewing effect of goldfish, but also cause death. Precautions for goldfish breeding: 1. Preparation of fish tank: when selecting, you should choose the shape you like and meet the home environment. The cylinder wall should be clear, transparent, smooth and flawless. Generally, place the fish 3 to 4 days before buying it, put pebbles and other bottom stones in it, and then fill it with clean water for use. On the one hand, it can make the water body mature, on the other hand, it can make algae grow on the cylinder wall, which is beneficial to the growth of goldfish. 2、 Selection of goldfish: goldfish cultured under good conditions: if the water body of goldfish is muddy, there is a lot of dirt in the water, the wall of the culture container (sink) is fuzzy, most goldfish float to the water surface, and the head floats one by one, which means that the operator of the place is not well managed, and the breeding conditions are poor, and the goldfish here may have internal injuries and poor physique, it is best not to choose, otherwise, the survival rate of the culture will also decline. Choose healthy and harmless goldfish: healthy goldfish have bright body color, complete scales and fins, symmetrical eyes and other characteristics. Carefully observe the body of the fish, and there are no white spots, no mildew and other pollutants on the body surface. In the clear water, it will look for food while close to the bottom stone, and not swim alone. Then fish these goldfish into another container to observe, and select the individuals you like. The goldfish whose body rubs against the four walls may have skin diseases such as rotifers on the body surface, which is usually hard to see with the naked eye, and should also be removed. Choose goldfish with beautiful shape: goldfish have many shapes and different varieties. The body shape can generally be divided into three types: lateral flat, oblate and middle. The lateral flat has the body shape of common crucian carp; The back is flat and curved; The intermediate type is between the two. A top-grade goldfish should have a short round body, symmetrical fins, neat scales, and obvious species characteristics. At the same time, the fish should be pure in color and not disorderly, balanced in body, soft in swimming posture and dancing in motion. In addition, in order to increase the ornamental value, the goldfish purchased at the same time should have different colors and shapes. 3、 Delivery of goldfish: 1. Shipment of goldfish: The purchased goldfish are generally shipped with water in plastic bags, and oxygen should be filled when far away from home. After long-distance transportation, they can be put into cartons. They are required not to feed goldfish on the first day, and not to put water plants during transportation to prevent decay and deterioration of water quality. 2. Placement of goldfish: The goldfish shipped should not be put into the fish tank immediately, but should be treated with "slow seedling" to keep the water temperature basically the same. The method is to put the plastic bag containing fish together with water and fish in the fish tank for about 20 minutes, and then slowly pour out the goldfish to make it enter the fish tank. Generally, a fish tank with a diameter of about 30 cm can put 2-3 goldfish with a body length of 3 cm, which can be reduced to 1-2 goldfish in hot summer. Larger ones can also be reduced as appropriate. 4、 Precautions for goldfish feeding: goldfish are cold-blooded animals, and their body temperature changes with the water temperature. Therefore, goldfish should pay attention to the following points during summer: the water temperature should not be too high. The temperature below 30 ℃ is appropriate. The aquarium should be covered with shade objects such as bamboo curtains outside. The temperature difference should not be too large. When changing water, if the water temperature difference exceeds 4 ℃~5 ℃, the goldfish nerve will be stimulated, causing the goldfish to stagnate, stop eating or become ill. If the water temperature is too high, slowly inject cold water immediately to reduce the water temperature. Don't overfeed. It is best to feed it once every morning, only if you can finish eating. You must not feed it too much, otherwise the goldfish will die of gluttony. The old water in the fish tank should be changed frequently. One third of the old water in the tank should be replaced every afternoon or evening, and the fish dung and food residue at the bottom of the tank should be removed
