The disease is characterised by proliferation of the skin. The disease causing agents freely swim on to the host or contact it by contiguity, or through a vector (the fish leech transmits Trypano- plasma in cyprinids causing sleeping sickness Trypanoplasmosis), or infection may be caused through the food medium which is already infected. Dull spots appear on the sides which subsequently becomes fused into a continuous greyish film. The fish may remain stationary in mid-water or stand on its head or lie at the bottom on its side. Various species of Myxobolus cause ulceration which appears either like a boil or knot or rice shaped. Young children and adults with weak immune systems are most commonly affected and may have diarrhea or blood infections. Symptoms include accumulation of fluid inside the body cavity, withering away of fins, scale protrusion and general edema. 6.46). The specific immune response of molluscs . Antibiotics and chemicals are common options to prevent and control of fish diseases, but their use is now restricted or even banned due to serious problems such as drug residues, pathogen resistance, and environmental pollution. Thus, it can be concluded that loss of genetic diversity in a selection process makes it difficult to develop strains of fish that are resistant to several other diseases at the same time. The main task is the prevention of diseases, which can be ensured by monitoring the water quality of the water supply source, as well as the use of a complex of veterinary and sanitary measures, including veterinary control over the transportation of fish, preventive quarantine of imported material and quarantine in dysfunctional farms . Affected fish hangs vertically in the water and shows loss of balance (spiral swimming). is rapidly becoming a major industry in many countries of the world and there will be a growing need for vaccines to control disease in a wide range of fish species in the future. They generally infect several cultiviable fish species. Several diseases are encountered by an aquaculturist particularly in semi-intensive and intensive systems of culture.

Control measures include interruption of the complex life cycle and prevention of transport of uninspected fish to new region. Subobjective 1B. Some of the major diseases, causative organisms, symptoms and treatment are listed in Table 6.14. The antibodies of fish (teleost) are serum proteins (immunoglobulins) that belong to IgM or IgG class. Red Worm. Wound healing is temperature dependent as the repair of dermis is suppressed by low temperature. On the other hand, the precipitating antibodies are less important in fish and they generally cause precipitation of soluble antigens which are easily discarded through tests. Prior to the appearance of white spots, fish may have shown signs of irritation, flashing, increased mucus, weakness, loss of appetite, and decreased activity. Viral infection was also found to be associated. The drug is incorporated in fish food in the case of bacterial infection. In fishes antibody formation is temperature dependent. Fishes affected with leech parasite are treated with a lysol (cresol and soap in 1: 1 ratio) bath (1 ml in 5 litres) for 15 seconds and then rinsed with fresh clear water.

The bacterium is rod-shaped measuring about 2 to 3 m in length. A new aquaculture therapeutant (peracetic acid) will be used to treat saprolegniasis on intact channel catfish eggs in hatching troughs. Even the disease- resistant fish that survives may develop a carrier state, which is harmful if the disease carrier is to be introduced into new areas where the disease would not otherwise occur. By the stimulation from certain antigens (bacteria, virus, etc.) (iii) Ponds when threatened with disease outbreak should be disinfected with either potassium permanganate (1 gm per 200 litres) or with 600 ppm benzalkonium chloride or calcium cyanamide. The parasite feeds on the cartilage of young host fish. The physical barriers generally restrict the entry of toxic, infectious and parasitic agents. Outbreak of argulosis is often fatal causing mass mortality. In some instances, antibiotics and surgical wound treatments are required to prevent deep infection. The recommended dose is 7.5 gm per 100 kg body weight per day for 1 to 2 weeks. The gonads get adversely affected with loss of fertility. Natural physical phenomena are fully used for disinfection in intensive fish culture due to their ecomical Adults should supervise hand washing for young children. Treatment measures via food is suitable only for such populations who are fed with artificial feed. Also, chemical treatment can be employed to rid in-flow of pathogens.

Infection by fish lice is one of the commonests. Fish and fish products are considered a fundamental part of the human diet due to their high nutritional value. The parasites of fish extract their nutrition from the host but do not harm it. Prevention: AddingPhenoxetholor Chloromycetin to feed can be an effective solution. Such infection is caused by the tapeworm (cestode), Ligula intestinal is (Fig. These antibodies bind the antigens rendering them less toxic and more vulnerable for easy phagocytosis. It enters the fish through the gills. Novotny L, Dvorska L, Lorencova A, Beran V, et al. Fish diseases caused by parasites, bacteria or viruses can be spread from pond to pond or from farm to farm by the transfer of infected fish and by animals, people, equipment and water contaminated by contact with infected fish or fish pathogens. Intestines are inflamed and the liver and kidney are affected. Do not release your pet outdoors. The swelling sometimes bursts releasing the content into the water (Fig. New Microbiologica.
