Anonymous users2024-02-11Summary. 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.

Anonymous users2024-02-10It needs to be controlled at about 25° for the following reasons:
Because marine fish is a fish that lives in the ocean, therefore, if we want to raise it, we must have relevant equipment and take relevant measures to simulate the living environment in the ocean. The temperature should be controlled at about 25, the salinity should be between 1·020% and 1·023%, and the flora and fauna of the sea should be placed. Only in this way can the saltwater fish happily live and work here and continue to live.

Anonymous users2024-02-091. Suitable for fish with low water temperature
In many people's minds, tropical fish are not suitable for low water temperatures. But in fact, some fish species are very adaptable and can grow even in cold and cautious water conditions. For example, boreal salmon, guppies, freshwater bass and other fish can adapt to life in waters with a water temperature of around 10.
Not only do these fish prefer a low-temperature environment, but they are also vigorous and vigorous, making them ideal for keeping in low-temperature water bodies.
2. Precautions for raising fish with low water temperature
There are also some precautions to be taken when keeping fish at low water temperatures. First of all, the fish tank needs to be insulated with insulation materials to keep the water temperature stable. Secondly, it is necessary to provide sufficient oxygen, and an aeration pump can be installed in the fish tank to ensure that there is enough oxygen in the fish tank.
In addition, in the selection of feed, you can choose high-protein, high-nutrition fish feed to strengthen the resistance of the fish body and prevent the appearance of diseases.
3. Reproduction of fish at low water temperature
Fish with low water temperatures have a relatively long reproductive cycle compared to tropical fish and need to reproduce in spring or autumn. At the same time, low-temperature fish also need suitable water temperature and sufficient nutrition to ensure the success rate of reproduction. It should be noted that in the process of breeding, it is necessary to pay attention to the monitoring of water quality and regularly replace the water body to ensure the healthy growth of the fish.
4. Profit of fish farming at low water temperature
The breeding cost of fish at low water temperature is relatively low, and the maintenance cost and feed cost of the fish tank are not high. Moreover, the low water temperature fish embodies the green pollution-free breeding concept of Tongzhu, the breeding time is long, the fish body is larger, the reproductive ability is strong, and it meets the market demand. Therefore, the farming of fish at low water temperature is relatively profitable and has broad development prospects.

Trout: belonging to the phylum chordates, salmoniformes, like to live in cold water, the suitable temperature is 16 to 18 degrees Celsius, all trout are spawning in streams, except for some living in streams, juveniles migrate to lakes or oceans to live, and then swim back to streams to spawn after growing into adults.
2. Salmon: Salmon belongs to the order Salmoniformes, salmonids, also known as salmon, is a kind of deep-sea fish, one of the foods that are often spared, and belongs to the cold and shelter-resistant water-based fish, with a suitable temperature of 11 to 14 degrees Celsius.
3. Sturgeon: It belongs to the phylum Chordates and Sturgeon, and has a wide range of temperature requirements for survival, and can survive in the water temperature of 13 to 30 degrees Celsius, and is distributed in China, North Korea and Japan in Asia.
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.
Fish farming is to look at the water quality first Golden dragon has very good genes It is already very strong in tropical fish As for it is difficult to raise, I don't think that a large number of artificial breeding seems to be within 10,000 yuan It is not very expensive. >>>More
Depending on your family's economic situation, if you can afford to raise it, you can get a pond of Japanese koi. In general, just raise ordinary small goldfish, get a scavenger fish, and don't feed too much, be careful that the fish is killed.
Adult pineapple fish are relatively susceptible to disease, but it is also very important to pay attention to some problems when feeding, otherwise it is difficult to raise pineapples in good condition. One is water quality. The big pineapple has a strong adaptability to water quality, not as high as the parrot's requirements, but it is also necessary to pay attention to maintaining the water quality it likes to raise excellent yellow fish, the big pineapple likes weak acidic soft water, with the parrot, be careful not to raise pineapples with alkaline or hard water, otherwise the color of the pineapple will be whitish and not yellow. >>>More
Herring is one of the four famous fish, also known as snail green, named because it likes to eat snails. In summer, herring is basically the target fish of most recreational anglers, so it is important to pay attention to the selection of fishing spots and bait to understand the living habits of herring. Next, the author will talk about the habits and fishing position selection of herring, and the skills of bait selection, I hope it can bring some help to all anglers. >>>More
