CATDOLL : CATDOLL: What feed do grass carp, silver carp and black carp fry eat to grow fast?

What kind of feed do grass carp, silver carp and black carp fry eat to grow fast?

Before summer flowers, soy milk is basically used for cultivation.

When they grow to about 2 cm, they begin to differentiate, and black carp and silver carp start to feed on zooplankton, mainly cladocerans, copepods, rotifers, etc.

At this time, grass carp begins to ingest organic matter in the water, while silver carp mainly filters algae.

After the summer flowers, they are basically fed with pellet feed, including powder, sinking pellets, expanded feed, etc. The main domestic feed manufacturers are: Tongwei, Haida, New Hope, Zhengda, Liuhe (currently integrated by New Hope), Zhenghong, and local feed factories such as Zhengbang, Dajiang, Sihai, Yuehai, Haixiexiexin, Haima, Tianma, Shuangbao, Tieqi Lishi, etc. You can ask the local dealer, who will recommend you the corresponding full-price mixed feed.

Thank you QQ pest for your answer,

It seems that farmers rarely raise black carp. Is it because it is difficult to raise?

Among the many fish species, black carp is one of the four major fish species, which shows that this fish still has a very high status in people's hearts. However, black carp is rarely available in the market now, and fewer and fewer people are willing to raise black carp, because farmers think that the black carp breeding cycle is too long, and it is difficult to sell it after it is raised, and it is simply impossible to recover the cost, so they are unwilling to raise it.

Black carp is a fish that grows relatively slowly. If you really want to raise it, you need to have enough patience and long-term investment. Generally speaking, the bigger the black carp is, the higher the price will be. However, if farmers want to raise a black carp weighing 10 to 20 kilograms, it will take about three years. If you only raise it for one year, the weight of the black carp will only be a few kilograms, and you will only lose money if you sell it at that time. In addition, the growth of black carp is not obvious at the beginning, and it will only grow faster in the later stage, but many farmers simply do not have the time, energy and funds to wait, so few people are willing to take this risk.

If farmers raise black carp, small black carp are not profitable, and large black carp are not good. A black carp is basically sold for more than 20 kilograms, but ordinary families will not buy such heavy fish, because they cannot be eaten if they are too big, and it will only be wasted. Therefore, black carp can only be sold to restaurants or places with large daily demand, but such places are few after all, so many fish sellers are unwilling to sell black carp. A large and heavy black carp can be sold for hundreds of yuan, but normal people are basically not willing to spend this money to buy it, so the sales are not very good.

The cost of raising black carp is actually very high. After all, it takes a long time to feed a fish from childhood to adulthood, and it needs to be fed every day during this period. Black carp will eat some small fish, shrimps or creatures like snails during its growth, but some fish will also eat some grass in the fish pond and are completely self-sufficient. Therefore, the living habits of black carp are also a big trouble for farmers. They have to buy feed frequently, and the cost of investment is too high, and they are particularly afraid of not being able to recover their investment.

Because it is difficult to raise, black carp is particularly difficult to raise in the fry stage, the survival rate is extremely low, and its growth rate is relatively slow, so most people can't afford to raise it for such a long time.

Yes, black carp is difficult to raise and the survival rate is not high. If you are not careful, you will suffer losses.

Mainly because the bait for raising black carp is relatively simple and the cost is relatively high, it is mainly based on its living habits, market consumption, breeding benefits and other aspects for consideration.
