Increase the productivity of goldfish
In recent years, the demand for ornamental goldfish in international and domestic markets has become increasingly strong, and the development prospects are very broad. The key to improving the benefits of goldfish culture is to increase its fertility. Strengthening management from the following aspects can greatly increase the goldfish oviposition. For broodstock breeding, goldfish must enter the peak of spawning as soon as possible, and broodstock must be cultivated in the spring. Choose a beautiful, well-developed male and female fish as broodstock in separate ponds. The water temperature is controlled between 14 and 28°C. Changing the water at least once a week requires sufficient, fresh, clean and nutritious feed to promote recovery of the physique after wintering. Pairing male and female broodstock must be reasonable, and grouping must be timely to ensure smooth broodstock spawning and improve fertility rates. A good ratio of male to female is 2:3, and at the same time, the broodstock that was originally grown separately to reach sexual maturity is selected to be merged before the first 3 days. The optimum breeding water temperature for goldfish control is 18°C. When the water temperature is lower than 10°C or higher than 29°C, the goldfish spawning process will be interrupted. When the water temperature reaches 28~14°C, sexually mature broodstock will gradually enter the estrus spawning period. In order to prolong the breeding season, in the breeding season of goldfish, various measures should be taken to keep the water temperature within a suitable range. At the same time, it is necessary to prevent sudden increase in water temperature, especially in the process of temperature changes, water changes, etc., but also pay special attention to the control of the water temperature, so that the amplitude of its rise and fall within the 4 °C range. Changes in the weather that affect the weather directly affect the spawning of goldfish, and the autumn weather can stimulate and stabilize the libido of the broodstock, thereby promoting its massive spawning. On the other hand, low temperature, low pressure, and hot weather will inhibit broodstock spawning. Therefore, we must pay close attention to the changes in the weather and choose the best weather for breeding. Adjusting water quality At a suitable water temperature, a constant water quality stabilizes the libido's sexual desire and delays spawning. By replacing the water and accelerating the change of water density, the broodstock can be excited and stimulate large quantities of eggs spawning under the stimulation of new water. Moderate stimulation of moderate stimulation stimulates libido libido and prompts broodstock to concentrate large numbers of eggs. Physiological stimuli are heterosexual stimuli. During the breeding season, female broodstock secretes hormones to attract males, and males chase females to hit females, prompting both parties to become excited and complete spawning and insemination. Physical stimulation method: First, small fluctuations in water temperature can stimulate spawning of broodstock; second, sudden changes in the weather indirectly stimulate sexual desire; third, change the water environment to stimulate; and fourth, place artificial fish nests to stimulate. Prevent and treat the broodstock before returning to the pool and wash with 5-4% saline for 5 minutes to kill the bacteria. Pay attention to daily management, remove residual bait dirt at any time, prevent livestock and poultry from going down the pond, and keep the environment quiet.
