A Detailed Explanation of Goldfish Rearing Methods and Key Technical Points
When keeping goldfish, the water must be clear. If it is tap water, it is best to let it sit for two or three days before use. At the same time, change the water frequently. Generally, in summer, change 1/3 of the water every three or four days, and in spring and autumn, change 1/3 of the water every week, and scoop out the excrement and excess feed to ensure the water quality is clean. At the same time, the water temperature should be controlled at 20-28 degrees, and feed small shrimp, earthworms, or special feed regularly and in fixed amounts, to avoid overeating and causing indigestion.
In addition to the above methods, the following points should also be noted:
1. The rearing pond must be clean: Before keeping goldfish, we should not rush to stock the fry. First, use quicklime or a special pond-clearing agent to clean and disinfect the rearing pond. Wait until the agent has evaporated, then fill it with new water. Then, after conducting a trial rearing with the water in the pond, put the goldfish fry into the rearing pond. Also, in the later rearing process, we need to frequently clean the rearing pond and disinfect it regularly to maintain a good environment, thereby increasing the yield of goldfish.
2. Water temperature: The most suitable water temperature for goldfish survival is 18-22 degrees. We need to keep the water temperature within this range. The water temperature must not be lower than 15 degrees at minimum, and not higher than 28 degrees at maximum, otherwise it will seriously affect the growth and reproduction of goldfish.
3. Reasonable feeding: When feeding, feed at fixed times, in fixed amounts, at fixed locations, and with fixed quality. According to the growth conditions of the goldfish, reasonably divide them into groups, and reasonably prepare feed according to the different groups.
4. The water quality must be clear: Generally, we change the water about every five days. Each time we change the water, we cannot replace all of it; a portion of the old water must be retained. If it is all replaced with new water, the goldfish will not survive easily. Also, after feeding, promptly scoop out the feed residue to avoid polluting the water quality. In addition, it is best to install an oxygen supply device in the rearing pond, preferably an oxygen supply agent, to replenish the oxygen content in the water at any time.
