Goldfish (definite introduction)
Spring is the best time for goldfish to grow. , many growers will carry out the growth and training of goldfish during this season. During the growth period of goldfish, there are certain requirements for the pairing, water temperature, environment and water quality of goldfish. Especially in terms of feeding goldfish, fresh nutrients must be prepared for goldfish. Feed to keep goldfish healthy.
1. Pairing of male and female goldfish
The pairing of male and female goldfish must be reasonable and the gregariousness must be timely in order to ensure the success of goldfish spawning and increase fertilization. Rate. A better male-to-male ratio is 2:3. At the same time, 3 days before delivery are used to urge the union of sexually mature goldfish that were originally separated and bred.
2. Control the water temperature
Control the water temperature. The optimal water temperature for goldfish growth is 18℃. When the water temperature is lower than 10℃ or higher than 29℃, The goldfish spawning process will be interrupted. When the water temperature reaches between 28 and 14°C, sexually mature goldfish will continue to enter the estrus and spawning period. In order to extend the growth period, during the growth season of goldfish, various methods should be used to control the water temperature within a suitable range. At the same time, it is necessary to prevent sudden rises and falls in the water temperature, especially during changes in temperature, water changes, etc., special attention must be paid to water temperature control to control the rise and fall within the range of 4°C.
3. Pay attention to climate changes
Weather changes directly affect the spawning of goldfish. The crisp autumn weather can stimulate and calm the sexual desire of goldfish, and then Promote its mass spawning. On the contrary, low temperature, low pressure, and hot weather will inhibit goldfish from spawning. Therefore, we should pay close attention to climate changes and adopt the best climate matching for development.
4. Water quality requirements
Arrange the water quality at the appropriate water temperature. Constant water quality will calm the sex drive of goldfish and delay spawning. By changing the water, accelerating the water density, etc., the goldfish can be stimulated by the new water and gather a large number of eggs to lay eggs.
5. Over-stimulation
Over-stimulation can stimulate the sexual desire of goldfish and urge the goldfish to gather and lay eggs in large numbers. Psychological stimulation is the stimulation of the opposite sex. During the growth period, the female goldfish will secrete hormones to induce the male fish, and the male goldfish will chase and hit the female goldfish, urging both parties to reach the excitement to complete spawning and insemination. physical stingStimulation method: First, strong fluctuations in water temperature can stimulate goldfish to spawn; second, sudden strong changes in weather can stimulate sexual desire; third, change the water environment to stimulate; fourth, place artificial fish nests to stimulate.
6. Environmental requirements
1. The living environment of goldfish is a water body, and the quality of the water body determines the quality of its living environment. Goldfish are highly adaptable and do not have particularly strict requirements for water quality. In addition, the water used to raise goldfish has been strictly tested and selected and generally does not contain toxic substances. The factors closely related to the metabolism, growth and development of goldfish are described below.
2. Meteorological factors mainly include physical factors such as temperature, light, humidity, falling water, wind, rain (snow), etc. None of them have a uniform impact on the survival of goldfish, but the main factor that has a direct impact on the survival of goldfish is temperature. Because the water bodies in which goldfish are raised are relatively small, changes in weather can quickly affect changes in water temperature, and a sudden rise in water temperature Falling off often causes the goldfish to become uncomfortable or sick, or even die. This proves that goldfish are very sensitive to sudden changes in water temperature, especially in the juvenile stage. Although goldfish can exist in water with a temperature of 0-39°C, in this range of water temperature, if the water temperature gradient exceeds 7-8°C, goldfish will easily become sick. No matter how large the gradient is, goldfish will become sick. sacrifice. Therefore, special attention should be paid to changes in water temperature during sudden changes in weather or when changing water in a goldfish pond.
3. The optimal water temperature for goldfish survival is 20-28°C. Within this temperature range, the higher the water temperature, the stronger the goldfish’s metabolism and the faster it will grow and develop. At this time, the goldfish swim vigorously, have a strong appetite, are physically strong, and have beautiful colors. When raising goldfish, the water temperature should be controlled within the range of 20-28°C as much as possible.
In terms of pairing goldfish with males, we need to use beautiful, well-developed males and females as goldfish to cultivate and grow in separate tanks. The water temperature is optimally controlled between 14 and 28°C. Be careful not to change the water once, only in this way can the growth of goldfish be improved.
