The causative agent of ornamental fish lice disease is fish lice, which is a small crustacean water pest, which is very similar to bed bugs, so it is commonly known as water bed bugs. Because fish lice are attached to the surface of the fish body and suck the blood and body fluids of the fish, it is an invasive disease and is very harmful to the fish.

Fish lice are insects that attach firmly to the body of the fish and can swim freely in the water at any time. It can be transferred to another fish at will, or it can swim down the river in search of a host. Fish lice live in ditches and puddles, and the vigorous breeding period is from May to August.

When keepers go to ditches and puddles to collect daphnia (fish insects), some fish lice eggs or larvae are also retrieved along with the daphnia. If you don't pay attention to the bait and put it into the fish pond, it will cause lice infestation. Some fish farms put fish in rivers, lakes or large puddles to raise them in pens or cages, and fish lice swim along the water and drill into the mesh to attach to the fish body; Some of them did not disinfect and inspect the collected aquatic plants before planting them in the fish pond (pot), and the nits attached to the aquatic plants were multiplied in the goldfish pond and caused lice infestation.

1. The fish lice resemble a bed bug, slightly transparent, gray-green body, slightly yellow in the egg period, and about 3-4 mm in length.

2. Pathogens are mostly parasitic on the body of goldfish, and it is rare for tropical fish to suffer from this disease. When parasitizing, it adsorbs on the body of the fish with a pair of suction cups, and lives by sucking the blood of the fish.

3. In the parasitic life, fish lice often crawl on the body of the fish, tearing the epidermis and muscle tissue, making the fish itchy and unbearable. In the early days, the sick fish swim rapidly and are irritable, sometimes rubbing their bodies against the bottom and walls of the pond in order to get rid of the pain. Fish parasitized by fish lice have a loss of appetite, a gradual thinning of their physique, and a decrease in their ability to resist diseases.

4. When bacteria, water mold and other microorganisms invade the wound torn by fish lice, the disease occurs, resulting in the death of the fish. The peak season for fish lice to breed and grow is from April to August, and the epidemic area is widespread.

2. What is the cause of fish lice on fish ponds?

Fish lice are a relatively normal phenomenon, generally in ponds and other places, if the pond cleaning work is not done thoroughly, or there is contact with other waters, it will easily lead to the invasion of such organisms. Fish lice generally parasitize the tail, dorsal and pelvic fins of fish, and in most cases more often on the caudal fin. If you look closely, fish lice can be clearly observed.

2. There will be more and more fish lice in the later stage, and then they will reproduce in the pond, and the tail of the fish will ulcerate in serious cases, and some abnormal reactions may occur. For example, they swim suddenly and quickly, constantly rubbing the tail fin, etc., and if the situation is severe, they will lose their balance.

3. Fish lice rarely attach to the outer edge of the tail, and most of the time, they will attach to the middle of the tail, so they look very blurry visually. In general, pure black fish are the most difficult to detect, and if they are not visible, it will be very difficult to remove.
