CATDOLL : CATDOLL: When is the best time to raise fish? (Which season is the best time to raise fish?)

1. When is the best time to release fish fry?

The period from late May to mid-June is the best time to stock fish fry.

It can also be one or two months after the New Year or in July or August.

The following points must be noted when releasing fish fry:

Pond cleaning and disinfection: 10 to 15 days before the fry are released into the pond, use 60 to 100 kg of quicklime or 13.5 kg of bleaching powder dissolved in water per mu and then spray the entire pond for disinfection; conduct a toxicity test on the cleaned pond water.

Method: One day before stocking the fry, take a few fish and put them in the fish pond net cage, observe for 6 to 8 hours, and if the fry are active normally, you can release them.

2. Which month is suitable to release fish fry?

One or two months after the Chinese New Year is a good time to release fish fry in spring. Spring and summer are the peak seasons for releasing fry in aquaculture. Farmers should pay attention to the following points to ensure the survival rate of fry in the pond.

1. Go to the pond on a sunny day. It is best to go to the pond in the morning when the fish fry adapt the fastest and have the highest survival rate.

2. Stock the fish in the pond with strong fry. Before stocking the fish in the pond, select the good-quality fish fry with strong physique, uniform size and active mobility to increase the survival rate.

3. Safe release into the pond. Before releasing the fry into the pond, it is necessary to strictly check whether the pond cleaning drugs have completely lost their effectiveness. First, try to release dozens of fry into the net cages in the pond and observe for a day and night to see if the fry are active and whether there are any abnormalities in the floating heads. If the fry are restless, struggling, or swimming around, it means that there are still some residues of the pond cleaning drugs. The fry can be released only after the drug effect has completely disappeared.

4. "Harmless" release into the pond. Since the fry are small, they have a weak ability to resist the attack of harmful organisms. Before releasing the fry into the pond, the whole pond must be netted 1-2 times with a fine mesh net to remove harmful insects, frog eggs, tadpoles, wild fish and other organisms that may harm the fry, so as to ensure the safety of the fry.

5. Stock the pond at the right time. If the fry are too weak and have poor vitality, the survival rate will be low if they are stocked too early. On the contrary, if the fry are too late, their yolk sac has been completely absorbed, their physical condition has deteriorated, and they are prone to death. The best time to stock the pond is when the fry are 4 to 5 days after hatching and can swim freely and eat food.

6. Start feeding and stocking the fish. On the afternoon of the day before stocking, feed 2 cooked egg yolks for every 10,000 fry. Wrap them in gauze, crush them, wash them and make egg yolk juice to feed the fish. Feed them again in the morning of the same day, increase the number of egg yolks to 4, and stock the fish at noon.

7. Stock the pond in the same batch. The fry stocked in the pond each time must be fry of the same species cultivated in the same batch. It is strictly forbidden to mix fry of different sizes and species, otherwise it will seriously affect the survival rate of the fry.

8. Adjust the temperature before putting the fry into the pond. For fry transported from other places, especially those transported in nylon bags with oxygen, since the water temperature in the bag is closely related to the pond water temperature, you can open the nylon bag first, put the bag into the pond, and add some pond water. After dozens of minutes, when the temperature inside and outside the bag is basically the same, you can put the fry into the pond.

3. In which season is the survival rate of released fish high?

The survival rate of fish released in summer is high.

Spring is the best time to raise fish. With the passing of winter and the coming of spring, all things revive and are full of renewal. Raise beautiful little fish in the spring and let them swim freely in the fish tank. Go for an outing in the woods in spring, enjoy the fresh and delicious air and warm sunshine, and look for little earthworms. Use little earthworms and corn flour to make food that fish love, and the fish will thrive happily in the water.
