What should be the water temperature for keeping small fish
How much should the water temperature of raising small fish
How much should the water temperature of raising small fish, in our life, fish has a good significance, many families will raise some fish in the home, there are so much to say about raising fish, need to be especially careful, then, how much should the water temperature of raising small fish? And I come together to understand it.
How much water temperature should raise small fish 1
The optimal temperature for the growth of goldfish in 20-28 degrees Celsius, this water temperature, goldfish growth and development of the most exuberant, food, excretion, and oxygen consumption are the largest, this time the goldfish is the most colorful and lively.
The goldfish in the 15-20 degrees Celsius water temperature, life activities are also very normal, just not the optimal temperature so exuberant, but at this temperature the water quality can be maintained for a longer period of time. Thus, the water temperature can be controlled at 15-20 degrees Celsius.
:
Difference in body shape: male goldfish generally have a slightly longer body, while female goldfish have a shorter and rounder body. Females have a larger abdomen than males during the egg-laying period.
Differences in caudal peduncle: Males are slightly thicker and longer than females.
Differences in the pectoral fins: on closer inspection, males are slightly longer and more pointed, with the first pectoral fin spine being thicker and harder; females are shorter and rounded, with the first pectoral fin spine being less hard.
Differences in genitalia: when viewed from the belly upwards, the male's genitalia are small, narrow and concave; the female's genitalia are large, slightly rounded and bulging outwards.
Different male and female goldfish, there is a slight difference in body color, the male fish is generally brightly colored, while the female fish is slightly lighter, in the reproductive development period, the male fish body color is more brightly colored.
How much water temperature should be 2Goldfish adaptability to the water temperature, in 0-39 degrees can survive, the best water temperature is 20-28 degrees, in this water temperature goldfish appetite, strong body, but also very active, and even the body color is more than usual look more bright and shiny. But the goldfish live in the water temperature is best not to have a sudden change, if the water temperature changes more than 7, 8 degrees, the fish will not adapt to the surface of the disease, the situation will be serious to promote the death of young goldfish on the change of water temperature is more sensitive to some, so goldfish enthusiasts should be very careful to pay attention to this issue.
1, breeding temperature, in addition to the black Mary has not bred other fish, so do not say much here, check the information found that the breeding temperature will be slightly elevated, generally 2 to 3 ° higher for the best, which can stimulate them to heat and start spawning.
-- The temperature for hatching young fish is generally better around 27~28°, which can stimulate their growth and development.
2. For example, peacockfish and swordtails can tolerate low temperatures of about 10°, while colorful fairy fish and tiger fish will die at temperatures below 18°.
3. Cold-water fish, that is, goldfish, koi and some local native fish.
The growth limit temperature of adult fish is 0-30 degrees, the appropriate growth temperature is 12-20 degrees, and the optimal growth temperature is 16-18 degrees.
If the temperature is lower than 8 degrees or higher than 20 degrees, the appetite will be reduced and the growth will be slow.
More than 24 degrees, feeding stops, body failure and death.
27-30 degrees, short time.
Therefore, the water source for cold-water fish farming needs to be clear micro-flow water, not turbid, not polluted, the annual water temperature varies within the range of 5-20 degrees, and the average annual water temperature is 8-15 degrees, which is the ideal water for aquaculture.
How much water temperature should be used to raise small fish3The living environment of goldfish has undergone thousands of years of change, the original result should be that they also experienced thousands of years of refinement, but due to excessive human intervention, such as excessive hybridization and over-medication, so that most of the goldfish's physique is not as good as before, in fact, goldfish is originally evolved from the carp, it is reasonable to say that their 'adaptability should be very The first time I saw this, it was a very good thing that I was able to get it to work.
Fish farming old road remembered thirty years ago had read a book on fish farming is clearly documented, goldfish tolerance temperature is between 0 degrees Celsius to 39 degrees Celsius, this is a little bit of a mistake, although including temperature, light, climate, air pressure, and even frost, snow, and rain on the growth of the goldfish will have a certain impact, but for the goldfish this kind of aquarium organisms, the most influential factor is still the temperature. The most influential factor is still the temperature.
Nowadays, most goldfish are kept indoors, which makes them happy in a sense, but also turns them into flowers in a greenhouse. However, when the seasons change, the temperature of the water changes dramatically, so the goldfish will obviously feel uncomfortable, such as: lazy swimming and refusing to eat, shrinking fins lying in the tank, and even suffering from white spots and scales, the source of these diseases are not related to the temperature change.
Although goldfish can tolerate high and low temperatures, but it does not mean that they can tolerate a large temperature difference, especially in the goldfish larvae, this feeling will be more obvious, in general, goldfish in the hatching period of the day and night temperature difference as far as possible not more than three degrees above, and in the fry period of the temperature difference is best not more than five degrees, the adult fish period of the day and night temperature difference not more than seven degrees.
The data provided here by the old fish farmers mainly refers to the outdoor ponds, has adapted to some of the day and night temperature difference between the goldfish, if it is in the indoor aquarium year-round breeding, this kind of temperature difference between those greenhouse flowers as usual can not be adapted to, and the corresponding values are to be reduced.
The most adapted life of goldfish water temperature in 20-28 degrees, goldfish in this temperature range, the higher the temperature of their metabolism will be the more vigorous, increased appetite, rapid growth, colorful, lively. But here is also a limit value, when the water temperature exceeds 30 degrees above, the goldfish's functions will begin to decline, higher than 35 degrees above, although part of the goldfish can also be tolerated, but for them has been quite dangerous, especially now living in the greenhouse goldfish have to be more careful.
Similarly, when the water temperature is lower than 10 degrees below the goldfish will appear slow metabolism until the gradual stop eating, when the winter outdoor water temperature is close to zero degrees, living outdoors all year round goldfish on the complete hibernation, only to wait until the coming spring when the water temperature reaches 10 degrees or so, they began to feed normally.
