embryonic development 1. Causes: The conditions for hatching of koi carp are poor, most notably caused by abnormal water temperature. When the small fish just came out of the membrane, the water temperature changed suddenly. At this time, the physical quality of the small koi carp was relatively weak. After being stimulated, it would appear toxoplasmosis.
2. Treatment: In this case, it is very difficult to treat, and there is basically no possibility of cure. Although the aesthetic feeling is low, it is necessary to feed the fish normally, and do not abuse the fish. This kind of disease starts with prevention, and the water temperature during breeding must be stable at about 28 degrees, so that the quality of the cubs is high.
1, the reason: Koi's brain has a compound mouth worm, the body will appear bent, and the bow is more and more severe. In addition, Myxosoma cerebri can also parasitize the cartilage and vertebrae of fish, causing the head of fish to deform and the spine to bend.
2. Treatment method: Sprinkle copper sulfate solution into the whole pool, and the concentration of the drug is 0.7 G/m. Sprinkle the liquid medicine into the fish tank every 24 hours.
1. Cause: If the water contains mercury, the koi will have osteoporosis and decalcification, so the body will bend.
2, remedial method: Change water to remove partial heavy metal, interval a few days, heavy metal disappeared, the straight line feeling of the body can restore slowly.
1. Reason: In order to make the koi grow and color, the inferior feed is mixed with a large number of illegal drugs, which causes the spine of the koi to bend due to corrosion.
2. Treatment method: immediately replace the healthy feed, and immediately stop feeding and dispose of the inferior feed.
