夏季金鱼安全的六个要点

金鱼（细节）

夏季是金鱼最有问题的季节。如果你在夏天不好好管理它，它很容易死亡。小编为大家整理了夏季金鱼管理的六个要点。新手鱼友可以学会在夏天让金鱼安全。

1、改善饲养环境。

水族馆应该放在光线充足、通风良好的环境中。水位稳定在20-25厘米，便于溶解氧照明。养在水族馆的金鱼要特别注意阳光，防止皮肤发霉、白斑病和皮肤充血。在条件允许的情况下，可以在池中填充空气，尤其是在夜间，这可以有效防止金鱼“窒息”，或者可以对给水进行物理过滤，使水变得干净，改善水中的溶解氧，提高给水透明度

2、调整放养密度

夏季气候变化直接影响水体溶解氧含量，放养密度不宜过大，原则上应小于春季

3、及时、适当地换水和注水

露天鱼塘的频繁降雨稀释了饲料水的浓度，减少了藻类和植物的分布，此外，光照不足，藻类的光合作用减弱，水中有机物分解产生的有害气体不能被水生植物充分吸收，容易破坏水质，造成水体溶解氧不足。一旦水质极度浑浊或溶解氧极低，应及时更换水。为了让金鱼安全度夏，最好用干净的水和绿色的水一起喂养它们，每天或每隔一天抽出一部分生水，然后加入等量的新水。换水和注水的水温和力度要平衡，一般温差限制在0.5-1℃

4、严格控制饵料量

此时是全年控制饵料量的困难季节。金鱼（幼鱼除外）食欲较弱，最好选择活水蚤，少食多食，10-20分钟吃完；或在春季和秋季喂食1/3-1/2的量，幼鱼除外。注意幼鱼的投喂、换水、注水控制

5、把握时机开展清洁工作

每天日落后的清洁工作是确保夜间安全的重要措施。除了清除水槽中残留的饵料、粪便和藻类尸体外，还需要仔细观察被有机物污染的池水。如果天气预报说晚上会有雷雨，清洁工作应该在暴雨之前完成。雨后夜间的观测工作应特别小心，发现问题应及时采取措施，以免因闷热造成不必要的损失

6、夏季加强观测尤为重要。不仅要加强夜间观察，防止鱼类窒息，还要加强白天对鱼体表、活动、觅食、粪便和水色的观察，根据鱼的健康状况及时采取必要的饲养和管理措施。应严格防止老年鱼安静地沉入池底。对于幼鱼，仔细观察体表，看看它们是否患有白斑病或有一层白云。这些是疾病的症状和症状。如果发现金鱼有异常行为，可以在鱼塘中喷洒1%的盐水或0.2%的红汞溶液，以减少诱饵的数量。经过2-3次的反复预防，可以保证幼鱼的健康；如果金鱼被发现是“顶级食物”，这意味着消化不良或食欲低下。第二天，停止进食或减少诱饵量

Six key points of goldfish safety in summer

Goldfish (details)

Summer is the most problematic season for goldfish. If you don't manage it well in summer, it is very easy to die. Xiao Bian has sorted out six key points of goldfish management in summer for you. Novice fish friends can learn to make your goldfish safe in summer

1、 Improve the feeding environment

The aquarium should be placed in an environment with sufficient light and good ventilation. The water level is stable at 20-25 cm, which is convenient for dissolved oxygen lighting. The goldfish raised in the aquarium should pay special attention to the sunlight to prevent skin mildew, white spot disease and skin congestion. When conditions permit, air can be filled in the pool, especially at night, which can effectively prevent goldfish from "suffocating", or the feed water can be physically filtered to make the water clean, improve the dissolved oxygen in the water, and improve the transparency of the feed water

2、 Adjust the stocking density

The change of climate in summer directly affects the dissolved oxygen content of water body, so the stocking density should not be too large, and in principle should be less than that in spring

3、 Timely and properly change water and inject water

Frequent rainfall in the open-air fish pond dilutes the concentration of feed water, reduces the distribution of algae and plants, in addition to the shortage of light, the photosynthesis of algae is weakened, and the harmful gases produced by the decomposition of organic substances in the water can not be fully absorbed by aquatic plants, which is easy to damage the water quality and cause insufficient dissolved oxygen in the water body. Once the water quality is extremely turbid or the dissolved oxygen is extremely low, the water should be changed in time. In order to make goldfish spend the summer safely, it is best to use clean water and green water to feed them together, draw out part of the raw water every day or every other day, and then add the same amount of new water. The water temperature and force of water change and water injection shall be balanced, and the general temperature difference is limited to 0.5-1 ℃

4、 Strictly control the amount of bait

At this time, it is a difficult season in the whole year to control the amount of bait. Goldfish (except young fish) have a weak appetite, so it is better to choose live water fleas, feed less and eat more, and take 10-20 minutes to finish eating; Or feed 1/3-1/2 of the amount in spring and autumn, except for young fish. Pay attention to the control of feeding, changing water and injecting water for young fish

5、 Grasp the opportunity to carry out cleaning work

The cleaning work after sunset every day is an important measure to ensure the safety at night. In addition to removing the residual bait, feces and algal corpses in the tank, it is also necessary to carefully observe the pool water polluted by organic matter. If the weather forecast is that there will be thunderstorm in the evening, the cleaning work should be completed before the rainstorm. The observation work at night after the rain should be particularly careful, and timely measures should be taken if problems are found, so as not to cause unnecessary losses due to stuffiness

6、 It is particularly important to strengthen observation

in summer. It is not only necessary to strengthen the observation at night to prevent fish suffocation, but also to strengthen the observation of fish body surface, activity, foraging, feces and water color during the day, so as to take necessary feeding and management measures in time according to the health of the fish. The elderly fish should be strictly prevented from sinking silently to the bottom of the pool. For young fish, carefully observe the body surface to see if they have white spot disease or have a layer of white cloud. These are the symptoms and symptoms of disease. If goldfish are found to have abnormal behavior, 1% salt water or 0.2% red mercury solution can be sprinkled in the fish pond to reduce the amount of bait. After 2-3 times of repeated prevention, the health of young fish can be guaranteed; If goldfish "top food" is found, it means indigestion or low appetite. The next day, stop eating or reduce the amount of bait
