1. Do you need trapped water for fish farming in well water Trapped water is needed for fish farming in well water, but trapped water alone is not enough. Generally, the temperature of well water is low, and the dissolved oxygen is not high. The water contains a large number of metal ions, so the hardness is relatively high. Such water cannot be used for fish farming directly. It is best to boil it first, filter out the impurities in it, and then oxygenate it before it can become water suitable for fish farming. Usually, tap water or river water is used for fish farming.
2. What are the requirements of water for fish farming1. Water temperature: The water for fish farming must pay attention to the temperature. If the temperature changes too much, it will be harmful to the health of fish. If it is some wide-temperature fish, it has strong adaptability to temperature. As long as it is not below zero, it is generally impossible to raise dead fish, but tropical fish are different, and the water temperature must be controlled between 20-30 ℃.
2, dissolved oxygen: Fish also need to breathe in water, so dissolved oxygen in water is also an important standard for fish farming. If it is a small fish, the oxygen consumption is not large, so there is no need for extra oxygenation, but the big fish is different. It must be oxygenated for 2-4 hours every day with an oxygen pump, otherwise it will float and die.
3. Water quality: Sometimes, although the water for fish farming looks clear, it is no longer suitable for fish to survive. The water quality is aging and the ammonia nitrogen content is too high, which will lead to fish poisoning and even death. Therefore, in order to maintain good water quality, it is necessary to change water regularly. After pumping out the old water, pour in a proper amount of new water.
