How to buy good doll fish fry

How can I buy good baby fish fry? When purchasing baby fish fry, farmers are often unable to accurately select fish fry. Here is the information about buying doll fry.

1, it is best to buy natural breeding seedlings from the mountains and gullies, with good resistance and strong immunity!

2. Stop eating for 1-3 days before buying, so that the fish will not spit and burst their belly, especially the seedlings.

3. Pick out the defective fish before buying the seedlings, pick out the sick seedlings first, and then check the boxes at last.

4. Doll fry are afraid of heat but not cold. It is best to add ice bottles and lids under the lid during transportation. Temperature is the main factor leading to death on the road, so low temperature is the best way.

5. And when you get home, don't rush to open the box to put the fish. Let the fish stay in the box for an hour or so. The waves on the road will cause the fish to get carsick.

6. It is very important to measure the water temperature in the box and the water temperature in the pond. The error had better be 1-2 degrees. If the error is too big, the fish can't stand it. The fish is a temperature-changing animal, and you have to slowly change the temperature to suit it! 4-5 cm seedlings should be more careful of the temperature change. The water temperature in the box is 1 degree higher and the water temperature in the pool is 1 degree lower. But the water temperature in the pool is high, and if you miss more than 2 degrees, the seedlings will die of heat. Many newcomers will die of heat. Very often, the fish is killed because of the water temperature, and it is also blamed for other people's fish fry, and there are not a small number of people who call and scold people who sell fish fry.

7. The baby fish saplings bought home are first put in the pond for a few days and then sterilized with germicidal water. Never use potassium permanganate and malachite green to disinfect and sterilize. The person who makes you do this is harmful to you. Some people even use bleach to sterilize the fish. This is a big mistake. Many people still can't find the reason for the death of the fish. Many people read a lot of things on the Internet and remember some wrong methods. Forget the good method, there are a lot of people like this, if you haven't raised it, ask the man-made policy first, pretending to know it can only make you short of money!
