1. How to breed goldfish?

Around the Qingming Festival every year, it is the season for goldfish to lay eggs and reproduce. In order to obtain excellent goldfish offspring, it is necessary to do a good job in breeding goldfish. So how can we breed good goldfish? 1. After the beginning of autumn or winter every year, select those goldfish that meet the requirements in terms of properties, characteristics and color as the key breeding objects of breeding fish. The specific requirements are: the same variety, the fish body is regular, the body is fat and plump, the color is bright, and the body length is 7 to 8 cm.

Avoid mixing different varieties of goldfish together, otherwise, the goldfish that are hatched in the future will become hybrids, neither fish nor fowl, and cannot be named. Of course, if you consciously want to breed new varieties, you should carry out hybridization purposefully and in a planned manner, and you must persevere in order to breed new varieties. 2. Do a good job in the feeding and care of the breeding fish. The breeding of breeding fish must be carried out under strict supervision, and the requirements are: feeding should be careful, and try to choose high-quality natural bait, such as live algae, water earthworms, etc. If it is artificial synthetic bait, it should be fresh and delicious. Do not feed the breeding fish with bait that goldfish do not like to eat.

The feeding time, quantity and feeding situation of the broodstock should be recorded in order to find out the rules and implement scientific management. The water should be used reasonably, the water quality should be kept good, and the water should be changed in time to keep the broodstock in a good living environment. A strong physique, lively spirit and bright skin color are the signs to observe whether the broodstock is in good condition. Daily feeding and management should be kept up, such as keeping the fish tank clean, and removing any dirt or leftover bait in time.

In rainy weather, oxygen should be added to the fish tank to reduce the amount of dissolved oxygen in the water. At noon in midsummer, the fish tank should be covered with some aquatic plants to provide shade, or placed in a cool place to prevent heatstroke or burns. 1. Provide a good "birthing bed" for breeding fish. Generally, prepare a piece of water grass, tie one end with a rope to fix it in the water. The water grass should be as hard as possible, and must be washed and disinfected before being placed in the fish tank, otherwise it will pollute the fish tank and affect the health of the breeding fish.

Baking soda is very beneficial to the growth and development of fish. According to this principle, if goldfish are soaked in 0.5-1% baking soda for a short time, it can not only greatly promote the life of young fish and increase their weight, but also have a significant strengthening effect on weaker fish and a certain effect on preventing various fish diseases.
