夏天给金鱼换水的方法

金鱼（细节）

夏天是金鱼生长和观赏的旺季。此时，金鱼池和池塘的水温升高，金鱼的食物消耗量急剧增加，金鱼群活动频繁，耗氧量显著增加，日照时间增加，光照强度增加。金鱼池和池塘的水深可以适当增加，以缓解夏季炎热，并有利于金鱼群体的生活。此外，还可以在烈日下的鱼缸上方适当增加芦苇帘等半遮荫，使金鱼在烈日下在水中有一个通风凉爽的环境。夏季换水量可适当增加，每天换水量可控制在盆（池）总水量的40%左右。夏季天气炎热，鱼缸里的水质很容易恶化。一天中最关键的时间是黎明和下午2-3点。此时，饲养者必须仔细检查金鱼种群的动态，发现异常时及时采取紧急措施，以挽救整个金鱼种群，否则整个种群将死亡。以上两个时刻是一天中最低和最高的温度。检查在下午2点至3点进行，以防止金鱼因水温和水质突然变化而烫伤尾鳍和背鳍；黎明前的检查是为了防止金鱼因水质恶化而死亡（俗称平底锅）。在炎热的夏季，当天气突然变化时，最有可能导致金鱼因高温和缺氧而漂浮和哭泣，甚至导致大量死亡。在黎明前检查金鱼时，你可以在黑暗中接近鱼缸，用手轻轻拍打鱼缸的边缘。如果金鱼立即沉入水池底部，这表明水中没有严重缺氧，也没有大量死亡的危险。如果鱼没有因振动而下沉，并继续漂浮和呼救，这是泛洪盆地的前兆，应立即采取措施，通过空气泵增加水体中的氧气或加水进行救援。在炎热的夏季，由于长时间暴露在阳光下或水质太老，金鱼的背鳍和尾鳍上经常有血斑或皮肤上有气泡。这是环境温度过高导致金鱼背鳍和尾鳍受损的前兆。这种损害主要发生在背鳍和尾鳍长大的金鱼物种中，如龙眼、帽子、红凤等。北京俗称热尾。及时救援的方法可以将受伤的金鱼移至一个相对较新、温度稍低的水中。轻的可在3至4天内恢复，严重的可被血斑和水泡损坏，导致鳍状缺陷和观赏价值损失，还可导致死亡。对于同一个人来说，从先前的烧伤中恢复起来更为困难。总之，由于夏季天气炎热，水温持续升高，每天换水的时间可以适当推迟。北京最好是在下午6点以后，最好的办法是在水池和水池取水和交换水后的晚上不要留下泥土和鱼和昆虫

The method of changing water for goldfish in summer

Goldfish (details)

Summer is the peak season for goldfish to grow and watch. At this time, the water temperature in goldfish basins and ponds increases, the goldfish's food consumption increases sharply, the goldfish group activities frequently, the oxygen consumption increases significantly, the sunshine duration increases, and the light intensity increases. The depth of water in goldfish basins and ponds can be appropriately increased to alleviate the summer heat and benefit the life of goldfish groups. In addition, semi-shade such as reed curtain can also be properly added above the fish basin in the hot sun to make the goldfish have a ventilated and cool environment in the water under the hot sun. The amount of water exchanged in summer can be increased appropriately, and the daily amount of water exchanged can be controlled at about 40% of the total amount of water in the basin (pool). Summer weather is hot, and the water quality in the fish basin is easy to deteriorate. The most critical time of the day is at dawn and 2-3 pm. At this time, the breeders must carefully check the dynamics of the goldfish population, and take emergency measures in time when finding abnormalities, in order to save the entire goldfish population, otherwise the whole population will die. The above two moments are the lowest and highest temperature of the day. The inspection is conducted at 2 to 3 p.m. to prevent goldfish from scalding their tail fins and dorsal fins due to sudden changes in water temperature and water quality; The inspection before dawn is to prevent the death of goldfish due to the deterioration of water quality (commonly known as pan basin). In hot summer, when the weather changes suddenly, it is most likely to cause goldfish to float and cry for water due to the heat and lack of oxygen, and even cause a large number of deaths. When inspecting the goldfish before dawn, you can approach the fishbowl in the dark and gently tap the edge of the fishbowl with your hand. If the goldfish immediately sink to the bottom of the basin, it indicates that there is no serious lack of oxygen in the water and there is no danger of a large number of deaths. If the fish do not sink due to vibration and continue to float and cry for water, it is a precursor of flooding basin, and immediate measures should be taken to increase the oxygen in the water body by air pump or add water for rescue. In the hot summer season, goldfish often have blood spots on their dorsal fins and tail fins or bubbles on their skin due to long exposure to the sun or too old water quality. This is the precursor of damage to goldfish's dorsal fins and tail fins due to high ambient temperature. This kind of damage mainly occurs in goldfish species with dorsal fins and tail fins growing up, such as dragon eyes, hats, red phoenix, etc. Beijing is commonly known as hot tail. The method of timely rescue can move the injured goldfish into a relatively new and slightly lower temperature water. The light ones can recover within 3 to 4 days, and the serious ones can be damaged by blood spots and blisters, resulting in fin-shaped defects and loss of ornamental value, and can also cause death. For the same individual, it is more difficult to recover from the previous burn. In short, due to the hot weather and the continuous increase of water temperature in summer, the time of daily exchange of water can be appropriately postponed. It is advisable for Beijing to move to the time after 6 p.m., and the best way is to leave no dirt and no fish and insects for the night after the basin and pool of water withdrawal and exchange
