The ten basis of fish disease judgment
Robust fishes are generally clustered, flexible, quick-acting and scared to dive into the water. Diseased fish usually travel alone out of the group, slow action, unresponsive, scared slightly after the dive, then slowly swim out of the water. When the fish has a parasitic disease such as sporozoites, it will go crazy or continue to jump on the surface of the water.
Second, based on the fish's food intake
When normal fish eat, they have strong feeding power and stable food intake. If you find that the food intake of fish is gradually reduced or even hunger strikes, the cause should be examined promptly.
Third, based on the body color changes in fish
All kinds of fish have their own unique body color, such as the occurrence of disease, there are body color changes, such as the incidence of gill disease, fish body color is black, especially in the head.
Fourth, based on the body shape of the fish to determine
Healthy fish has a small head, thick back, and good plumpness. Diseased fish have large heads, small tails, narrow backs, dry skin, and thin muscles. If the content of heavy metals in the water is too high, the fish will bend and deform.
Fifth, based on the disease fish organization judgment
The body of fish is the main basis for diagnosing fish diseases. Each diseased fish has its own special symptoms and needs to be carefully observed and distinguished in order to correctly diagnose fish diseases. In particular, fish diseases that depend on some symptoms need careful identification to find out the differences, such as the difference between enteritis and hemorrhage.
Six, based on the fish's habitat
Different types of fish have different conditions, so they can help diagnosis: for example, enteritis, red skin, rot, powdering, etc. occur in an acidic water environment; parasites such as Chinese sturgeon, anchor head lice, and fish lice. Occurred in a weakly alkaline water environment; pan-pool phenomenon occurs in anoxic environment.
VII. Judging from Seasonal Changes
Different fish diseases have different water temperatures, so different fish diseases can be distinguished according to different seasons. For example, grass carp hemorrhage occurs in the high-temperature season from July to September; vertical scale disease occurs in the spring and autumn seasons; water mold occurs in the late autumn and early spring seasons.
Eight, based on the growth stage of the fish
For example, sword leeches only harm the fry which has just hatched for one week. Fighting, whiteheads and white beetles mostly occur at the fry stage. Hemorrhagic disease of grass carp and enteritis disease of herring often occurs at the fingerling stage. Red skin disease and print diseases mostly occur at the adult stage.
Nine, based on the host's judgment
The pathogens that are parasitic by different pathogens are also different. Enteritis and hemorrhage mostly occur in blue and grass carp; lice and ticks are rarely affected; Chinese quails and so on only occur in crickets and squid.
Ten, according to the efficacy of judgment
If certain types of drugs, such as antibiotics, have no effect on certain fish diseases, bacterial or parasitic diseases should be considered.
Others, but also based on the actual situation, based on the growth of fish, fish secretions, urine and other parts of the secretions, based on human factors (such as poor management, improper application, water pollution, pesticide inflow, mechanical damage, etc. may trigger Fish disease) for diagnosis.
