Multiple diseases can easily lead to the symptomatic treatment of crazy swimming disease of fish.

Fish body surface or body parasites some parasites, which makes fish restless and crazy swimming, crazy disease, Chinese disease, zoonosis, rotifer disease, three generations of worm disease, symptoms are similar, the epidemic season is basically the same, so it is very easy to misdiagnosis, delay treatment, resulting in economic losses. The symptoms, prevention and treatment of these diseases are as follows:

Fish culture

First, madness. Symptoms: the fish swam wildly, swam in circles, lost their balance, sank to the bottom of the water and surfaced, with a large head and a thin body, an extremely upward tail, and sometimes water in the abdominal cavity. Prevention and control: (1) disinfect fish ponds with 125kg quicklime per mu to kill spores parasitic in the mud; regularly sprinkle 2.5% trichlorfon powder with a pond water concentration of 5 × 10E-6. (2) the whole pool was sprinkled with 90% crystal trichlorfon, the pond water concentration was 0.5 × 10E-6, and the rice bran soaked with 10 × 10E-6 dichlorvos (80% emulsion) or 10 × 10E-6 crystal trichlorfon was fed for 3 days.

Second, Chinese disease. Symptoms: the fish are restless, swimming or spinning on the surface of the water, the leaves on the caudal fin are above the water, the ends of the Gill filaments are swollen, inflamed, white and parasitic with many worms, visible to the naked eye, resembling small maggots. Prevention and cure: (1) the mixture of 5 ∶ 2 copper sulfate and ferrous sulfate was sprinkled all over the pool to make the pool at 0.7 × 10E-6. (2) 2.5% trichlorfon powder and ferrous sulfate mixture of 1.2 ∶ 0.2 were sprinkled throughout the pool with a concentration of 1.4 × 10E-6.

Third, suffering from illness. Symptoms: sick fish restless, swimming wildly in the water, jumping out of the water, the worm body is a large grain of rice, light blue-gray, visible to the naked eye. Prevention and treatment: (1) Pinus massoniana branches are tied into bundles and put in water, with 20 kg per mu of water surface, which has preventive effect. (2) the whole pool was sprinkled with 90% crystal trichlorfon, which was 0.3 × 10E-6~0.5 × 10E-6. (3) deltamethrin 6ml / mu (water depth 1 m), the effect is very good.

Fourth, rotifer disease. Symptoms: the diseased fish secrete a lot of mucus on the body surface, white nebula appears on the fin, head and body surface, and the fish swim wildly along the edge of the pond. Control: (1) retting water with 5kg of neem leaves per mu, once every 7 days, or sprinkling the juice of fresh branches and leaves of neem trees in the whole pool. (2) sprinkle the mixture of copper sulfate and ferrous sulfate (same as before). (3) 50% desenamine emulsion was sprinkled in the whole pool, and the concentration of pool water was 0.5 × 10E-6, which had special effect.

Fifth and third generation disease. Symptoms: there is a light blue film on the body surface of the fish. Careful observation of the body surface shows that there is fine hairy worm body activity. Causing extreme unease in the fish, sometimes swimming wildly, sometimes swimming sideways. Prevention and treatment: before stocking, soak the fish with 20 × 10E-6 potassium permanganate for 15 minutes for 30 minutes.
