Description

 The invention relates to the field of veterinary ichthyopathology, in particular to the development of a method for the treatment of gastrointestinal diseases: aeromonosis, pseudomonosis and bacterial hemorrhagic septicemia of fish.

 Aeromonosis (carp rubella, hemorrhagic septicemia, infectious abdominal dropsy) is an infectious disease of carp fish, characterized by inflammation of the skin, foci of hemorrhage, dropsy, ruffling of the scales, perspiration, hydration of muscle tissue and all internal organs.

 Pseudomonosis (rubella-like disease of carps) is an infectious disease characterized by the development of a general septic process with the appearance of general dropsy, erosion of scales, puchglazia and focal hemorrhage on the skin and fins; ulcers on the surface of the body of fish are absent.

 Bacterial hemorrhagic septicemia is a bacterial lesion of cyprinids, where, in contrast to aeromonosis, the causative agents are bacterial associations of various types of microorganisms.

 These diseases are ubiquitous and cause economic damage due to the death of part of the fish (up to 50-70%), a sharp decrease in the growth of muscle tissue, and the deterioration of the commercial quality of fish in the presence of superficial ulcers.

 Currently, there is a method of treating gastrointestinal diseases of fish with antibiotics "chloramphenicol" and "tetracycline", which are given with food at a dose of 50 mg / kg of fish weight for 5 days, then they take a 3-day break and the course is repeated [1].

 Also known is the preparation of polyvinyl ethinyltrimethylpiperidol with iodine (PVENTI) for the treatment and prevention of gastrointestinal and respiratory diseases of animals, which are diluted with distilled water 1:10 and 2 times a day are drunk at the rate of 3-5 ml / kg body weight for 5 days [2 ].

 The objective of our research was: to develop a method for the treatment of gastrointestinal diseases in fish, which provides efficacy with an affordable, inexpensive drug.

 The proposed method is as follows: take food intended for feeding a certain amount of fish and moisten it with a diluted preparation of polyvinyl ethinyltrimethylpiperidol with iodine (PVENTI) at a rate of 0.8-1.2 mg / kg of biomass and feed daily for 4-5 days.

 Example 1. For the treatment of trout with a disease caused by the association of microorganisms contained in a 3x3x2 m cage with a total biomass of 50 kg (average piece weight of fish was 50 g), a medicinal feed containing 0.8 mg of the medicinal product / kg (g / r) the mass of fish. Feed was given daily, once, for 4 days. Clinical signs of the disease disappeared 5 days after the end of therapeutic feeding. The number of fish with signs of disease decreased by 96%.

 Example 2. For the treatment of two-year-old carp (the disease is caused by pseudomonads) contained in the feeding pond and having a total biomass of 10 tons, a medicinal feed was prepared containing 1.0 mg of the preparation / kg (or g / t) of fish biomass. Feed was given daily, once, for 5 days. Before treatment, the number of fish with pronounced signs of the disease was 53%. 10 days after the course of treatment, the number of fish with lesions was less than 1%.

 Example 3. For the treatment of two-year-old carp, with aeromonosis contained in the feeding pond, having a total biomass of 13 tons, a therapeutic feed was prepared containing 1.2 mg of the preparation / kg of biomass (or g / t) of fish. Food was given daily, once, for 5 days. Before treatment, the number of fish with pronounced signs of the disease was 47%. 10 days after the course of treatment, the number of fish with lesions was less than 1%.

 As can be seen from the foregoing, the proposed method provides effective treatment of gastrointestinal diseases of fish within 4 to 5 days.

 The therapeutic product is domestic, affordable and inexpensive.

 The proposed method was tested by us with a positive result in fish farms "Biserevsky fish factory" and "Gzhelka" in 1997-1999.

 The method of treatment will find application in fish farms and will help to heal them from diseases.
