(Real shot aquatic workers help Koi spawn)
Everyone knows that there are two main breeding methods for koi, one is natural reproduction and the other is artificial reproduction.Now that many farmers have started to make fish farms, it is necessary to understand the koi farming methods during the koi farming process.For the development of fishing grounds, many choose the second, artificial propagation method.What are the benefits of artificial propagation methods?
The main advantages of artificial insemination are:
1) Higher insemination rate and higher incubation rate.
2) The eggs of artificial insemination can be randomly matched, that is to say, the eggs of displaced mother fish can be combined with the sperm of broodstock of different koi species in batches, so that several types of koi offspring can be matched.For example, a red-and-white female fish with a better texture and body shape can be artificially bred with red-white, Taisho, and Showa at the same time, which is a good way to multiply a baby.
Artificial propagation method of koi breeding method:
1. Put the broodstock close to the spawning period together to start rear-end. When the spawning begins, separate the male and female fish and let them rest for half an hour or an hour.
2. Prepare instruments and medicines during the rest of the broodstock, enough time to anesthetize them, and then disinfect the koi abdomen with Ringers potion, and the abdomen of the female fish should be 45 degrees down, and gently squeeze the early eggsGo to the vessel prepared for the poem.
3. To raise the abdomen of the male fish and squeeze the abdomen, the sperm white night will be eliminated. You can use a straw or a needle to suck the sperm into the container containing the Klines potion.
4. Sprinkle the mixed eggs onto the egg bed in the incubation tank. In the water, the eggs begin to be fertilized and begin to adhere to the ovaries. At the same time, they start to energize and oxygenate, and disinfect the fertilized eggs with methyl blue.
5. Around 1 hour, a lot of bubbles start to appear, which can break down the unfertilized eggs and fertilized eggs, which will affect the hatching water quality, so the bubbles must be removed several times a day, mainly to prevent the rotting of fish eggs.
6. The incubation time of fertilized eggs will be hatched in about 4-7 days if the weather has not changed much (especially temperature changes).
