CATDOLL : CATDOLL: How many carps can be raised in one acre of reservoir?

1. How many carps can be raised in one acre of reservoir?

Generally speaking, it is better to raise about 3,000 catties of carp per acre of pond, and about 300 catties of other fish. Too much stocking is prone to disease, and the breeding cost increases dramatically. Generally speaking, grass carp, silver carp and bighead carp are mixed! Now let's look at the highest breeding density of the four major carps in Henan, which can reach 10,000 catties! Generally speaking, 1 acre of pond can raise 2,000 to 3,000 catties of mixed breeding! Of course, there are also big differences in different regions, climate, environment, water quality, breeding technology and investment!

1 Single culture method: select a disinfected pond of 2-4 mu, 1-1.5 mu water depth, put 3000-6000 summer flower fish fingerlings/mu, feed compound feed or a mixture of bean cake, silkworm pupae, and fish meal, the protein content of the feed is required to be more than 35%, 8-12 times a day, and the feeding rate is 5-8%.

2. Mixed culture method: Mix carp with other fish species, carp can be the main or supplementary. If carp is the main species, feed should be increased. If silver carp is the main species, water quality can be properly cultivated. If grass carp is the main species, carp should be put in less.

2. Differences between carp and crucian carp fry

Carp has whiskers under its mouth, and its mouth grows downwards. Crucian carp has no whiskers, and its mouth is smaller than carp's, and it grows forwards.

The one with a pointed head is a carp. The one with a small head is a carp. The one with a big round head is a crucian carp. It's simple enough, isn't it?

3. Who knows the price of carp fry?

Hello friend, where are you from? I am from Kaifeng, Henan. My carp fry are a few to dozens per pound, and they cost about four yuan per pound.

4. The price of koi, seedlings...

The price difference is too big. Some varieties such as Tancho, Taisho, Showa, Akizu, Yamabuki, etc. are very expensive. The fish sold in the general flower and bird market (except for some shops that sell genuine ones) are all very poor quality, and the prices are also very high now. You can decide.

5. What is the price of Japanese Koi fry?

There are all kinds of koi in the big cities in the south, such as Dongguan and Guangzhou. Huawangyu Japanese koi is purebred. The price is hard to determine. It depends on the strain, appearance and size. Such as red and white, Taisho, Showa, autumn green, light yellow, fallen leaves, blue clothes, five colors, peacock, paste points, chrysanthemum water, red writing, white writing, silver scale, nine dragons, platinum, gold, etc. The cheap ones are a few yuan, and the expensive ones are too expensive!

6. How much does a koi cost? How many grades are there? I'm talking about seedlings! If you have pictures, please bring them. There will be a big reward.

I suggest you go to Zhongjin Academy to take a look at the introduction to koi, which has pictures and is worth appreciating.

There is only the saying of whether it is good or not, not the price. Some very beautiful koi are sold by fish shops with the water splash species, which also have many good varieties, and they are sold very cheaply, 8 yuan per piece (15-20CM). Some fish shops sell mediocre koi, with red and black koi and poor body shape, just like a scam, saying they are Japanese koi, 60 yuan per piece (15-20CM).

Generally, a koi must be over 20cm in length to be able to tell whether its posture is good or not. It is best if it is in a comb-shaped shape, slender, with a head that is not too big and looks even overall.

The red plate should be neat and clean. It is best not to have too much scattered red. The edges should be clear. Some parts can have some layers of red, but they should be neat and have a sense of flow.

Ink should not be presented in very small dots, which are called pockmarks. Ink has different shades, the deep one is very thick, and the light one is crimson blue, like a landscape painting.

Except for Showa, Taisho, and Hakusha, the red discs and black spots of general red and white, red-crowned, and beikuo koi should not cover the eyes or nose.

Ordinary fish shops usually sell koi by size, with prices ranging from 10 yuan for three 10cm to around 40 yuan for a 10cm-40cm piece.

If you go to a place that specializes in selling koi, the price of a good variety can be as high as 600 to 800 yuan for a 20CM fish fry.
