How to raise carp fish

It depends on whether you raise a big one or a small one. I have raised one before. I have some experience!

1. Choose a larger fish tank.

2. Rainwater is also OK.

3. Check it out. If it is dirty, very dirty, change the water.

4. You can release it whenever you want, it will not have any effect on the goldfish.

How do restaurants raise edible fish?

The main thing for restaurants is to do a good job of temporary rearing, that is, to keep the edible fish alive as much as possible from the time they are purchased to the time they are sold as dishes. To do a good job of temporary rearing, pay attention to the following points:

1. Cooling: Except for a few tropical species such as tilapia and freshwater silver pomfret, most fish, especially famous and high-quality species such as rainbow trout, turbot, and sturgeon, can withstand low temperatures. When the temperature is lowered, the metabolism slows down, and the excretion is reduced. While ensuring the water quality, the proportion of edible fish dying suddenly due to the stress effects of procurement and transportation is greatly reduced.

2. Oxygenation: Oxygenation is necessary. Oxygen is the first limiting factor for aquatic organisms. Water with higher dissolved oxygen is conducive to temporary breeding.

3. Pay attention to the breeding density: Don’t blindly reduce the procurement cost and centrally purchase live fish, which will lead to excessive breeding density in a single breeding unit. Generally, the species will stay in the restaurant for 1 to 3 days, and some easy-to-breed and precious species will stay for at most 1 week.

4. Don’t feed fish casually. Fish have a strong ability to tolerate hunger. Feeding them will speed up their metabolism, increase the burden on the water, and destroy their temporary breeding. Feeding must be done under the guidance of professional advice.
