If it is an animal, it will have a temperature, and the temperature of the fish in the water is also appropriate, and it is not good if it is too hot or too cold.

Tuna is quietly clogged and hot-blooded, and its body temperature can reach 33 to 35 degrees.
Tuna swim with their mouths open and their gill covers open to allow the water to pass through their gills for oxygen respiration. This characteristic makes it only possible to swim at high speed without stopping for the rest of its life, even at night, but only slows down the swimming speed and reduces metabolism. This tireless and rapid swim requires a strong muscle contraction, and it is this force that makes their bodies warmer and higher than the outside water temperature.
Tuna has a well-developed ** vascular system connected to the muscle on both sides of the spine and **, forming a large number of vascular clusters, and there is also blood flow in these vascular plexuses, indicating that the metabolism of these parts is particularly vigorous, therefore, the meat of this part of the tuna is purple-red instead of white. In addition, it has the same vascular plexus in the liver. The high metabolism makes the tuna's blood always maintain a relatively high temperature, so it can be regarded as a "hot blood animal".

Summary. Fish is an ectothermic animal, and its body temperature changes with the temperature of the living environment – the water. Experts have experimentally determined that the difference between the body temperature of the fish and the temperature of the water is in.
Therefore, the body temperature of the fish varies with the water temperature, and the change of the water temperature depends on the change of air temperature. Freshwater fish have different temperatures adapted to their survival due to different fish species and different living areas. When the water temperature is right, the fish appear to be active, have a strong appetite, and have strong fecundity.
If the water temperature is not suitable, the fish will become inactive and even stop eating. When the water temperature exceeds the critical threshold for the survival of the fish, the fish will die.
What is the best water temperature for freshwater fish
I see your question, please wait a moment.
Hello, I am glad to answer for you, the optimal water temperature for freshwater fish is 24-30 degrees. It is divided into landscape fish farming and edible freshwater fish farming. Freshwater aquarium fish have different water temperature requirements depending on the species:
1. The temperature of cold-water fish is 18-23 degrees. In summer, when the temperature exceeds 30 degrees Celsius, it is necessary to cool it down. 2. Small tropical fish, such as peacocks, neon, etc., 20-25 degrees 3. Medium and large tropical fish, such as parrots, arowana, etc., 28-30 degrees.
It is recommended that no matter what kind of fish you raise, it is best to control the temperature above 20 degrees Celsius to allow nitrifying bacteria to multiply. If the temperature is too low, the nitrifying bacteria will stop multiplying.
The optimum water temperature for carps is 25-32 degrees. The water body of the reservoir is in a certain degree of flow and exchange, and its dissolved oxygen is sufficient, stable, and vertically distributed. Dissolved oxygen on the surface can reach 7 10 milligrams of liters, reservoirs with thermocline, and little or no dissolved oxygen on the bottom.
Compared with ponds, reservoirs have high dissolved oxygen content and smaller diurnal and vertical variations.

Fish is a ectothermic animal, the body temperature is generally not fixed, it will change with the temperature of the water and the temperature of the living environment, according to experimental studies, the temperature difference between the body temperature of most fish and the water is around, usually higher, because metabolism will produce a certain amount of heat.
When the water temperature is suitable, the fish will appear active, have a strong appetite and have strong fecundity, and when the water temperature is not suitable, the fish will appear inactive and even stop eating, and if the water temperature exceeds the survival threshold, the fish will die.
In general, within a certain range, higher temperatures can promote faster growth, lower temperatures can make fish grow slower, and fish grown at high temperatures are larger than those grown at low temperatures.
Ectotherms, also known as cold-blooded animals, most of the animals on the earth are ectotherms, when the temperature of the external environment rises, the metabolic rate of the animal increases, and the body temperature gradually rises.

Summary. Hello, fish are ectotherms, and their body temperature varies with the water temperature, generally 1-2 degrees Celsius higher than the water temperature in which they are located.

Can fish survive grass carp in winter.
Can live. How to raise grass carp in winter, and how long it takes for grass carp in the south to adapt to the north.
In winter, it is more than ten degrees below zero, and grass carp can only be fed.
It can't be in the north, it's okay in the south.
I bought a few grass carp in ** and died in a week.
Why can't the north?
Is it very cold over there right now?
Under normal circumstances, the water temperature of 15 24 degrees is the comfortable temperature of the grass carp, and it is also the opening temperature of the grass carp.

Fish are not constant. Hydrophytic ectemic vertebrate taxa that breathes with gills, uses fins as locomotor organs, and is mostly covered with scales and lateral line sensory organs.
This is the definition of fish. It is shown that it is temperature change because its body temperature changes with the change of ambient temperature, unlike the body temperature of homeothermic animals does not change with the change of ambient temperature. This is mainly due to the fact that homeothermic animals have a fast metabolism and a perfect body temperature regulation mechanism, so they can maintain a constant body temperature (only birds and mammals are homeothermic animals).
Fish are scarce, so it gets warm.
We humans belong to homeothermic animals, and the body temperature is constant, so when the body surface comes into contact with a medium below the body temperature, the heat of the body will be taken away, and then the feeling of "cold" will occur.

Fish are ectotherms because its body temperature varies with the change in ambient temperature, and the body temperature of homeotherms does not change with the change in ambient temperature. Mainly due to the rapid metabolism of homeothermic animals and the perfect body temperature regulation mechanism, they can maintain constant body temperature, which is very necessary to maintain the normal progress of metabolism, only birds and mammals are homeothermic animals.

The water temperature is about 4 for about 3 meters, and if it's winter, the underwater temperature is generally higher than that on land. In general, fish eat slowly when it is below 10 degrees Celsius.
Water temperature: When talking about water temperature in life, it only refers to the temperature of the water. In geography, water temperature refers to the temperature of groundwater. The groundwater temperature discussed in general refers to the water temperature of the earth's crust.
Fish: Fishes are ectothermic aquatic vertebrates that are covered with bony scales, breathe with gills, use fins as locomotor organs, and feed on the upper and lower jaws.
-
The water temperature is generally 3-5 degrees higher than the air temperature. If the air temperature is 10°C, then the water temperature should be 13-15°C. If you don't eat at a certain level, it depends on what kind of fish.
-
In winter, the temperature under the water is generally higher than on land. It depends on what kind of fish you are, but generally fish eat slower than 10 degrees.

There are differences in body temperature in all parts of the human body, in the morning and evening, and between men and women. There is a relatively stable range of normal body temperature, but it is not constant. In a normal person, the oral temperature (also known as oral temperature) is lower than the axillary temperature and the rectal temperature (also known as anal temperature) is higher than the oral temperature. >>>More
