The exchange of fresh water in ponds is an important task in the management of aquaculture ponds. Both regular fish and shrimp and crab cultivation can improve water quality and promote growth. In actual production, the replacement of fresh water is appropriate, which is undoubtedly beneficial to aquaculture production. However, if it is not appropriate, it will cause huge losses in aquaculture production.
1. The amount of fresh water in the pond set is not more than 20% of the water in the pond, because too much water and water temperature in the pool will bring about changes in the degree of adaptation of the aquaculture product.
2. If the water source used is sometimes subject to pollution, and the water canal used by it is also public, it is necessary to check frequently if the pond is leaky. Natural water will enter the drain, and these holes will be blocked. Otherwise, the pond will inevitably Contaminated.
3. Long-term drought will turn stagnant water into water, causing water quality damage. Dumping heavy rain may also give polluting companies the opportunity to discharge large amounts of sewage. Therefore, before entering the water, the source water quality should be tested and the water can be tested. Success, we must pay close attention to changes in water quality during the entire process of water intake.
