| Project Name: | ||||
| Seasonal and Long-term Dynamics of Carp Family Invasion Diseases (Helminthiasis) of Skin and Body Cavities in the Soligorsk Rezervoir | ||||
| Project Type: | ||||

| Among the reasons interfering with high natural fish productivity of reservoirs it is necessary to note distribution of various diseases, including Helminthiasis , pathogenic organisms of which affect both fish and carnivores: fish-eating birds, some mammals including people.In the literature there is not enough information on distribution of illnesses of fishes in various reservoirs of Belarus and especially on concerning seasonal and long-term dynamics of fishes, infected with helminthiasis. We have spend 4 years( 2003-2006) carrying out biological analysis of the catch confiscated from poachers by fish wardens of the Nature Ward Organization to analyze the pattern of spreading of helminthiasis among carp fish in the Soligorsk reservoir.We examined the specimens of the bream, the silver crucian, the rudd, the silver bream, the small fry and the gudgeon, belonging to the carp family, and the specimens of the ruff and the perch, belonging to the perch family. In total 919 specimens of the mentioned species of fish were investigated. We diagnosed the diseases, determined the percentage correlations of infected and healthy specimens, defined the changes in biological characteristics of the fish infected with invasion diseases (Helminthiasis), compared the sickness rate in different seasons and years, compiled the corresponding chart and graphs. We determined that, the specimens of the silver bream, the small fry, the bream, the gudgeon, the rudd were infected with Postodiplostomos. It has been defined that in August Postodiplostomos sickness rate is higher than in the other months, which is connected with the completion of the evolution cycle in summer time. In the course of our research we revealed the changes in the numbers of sick with Postodiplostomos specimens, during the period of 4 years. Thus in 2005 the sickness rate was the highest(the silver bream -5.4%, the rudd-60%, the small fry- 38%,gudgeon- 100%) In 2006 we determined a fall in the sickness rate. We have determined that the species of the carp family under investigation were clean from invasions. The disease started to spread in 2004 was at the high in 2005 and in 2006 there was a fall in the number of infected fish. Only two specimens of the rudd out of 88 were affected by Lidulidos , which comprises 2.3% in 2003, and the specimens of the silver crucian were clean from invasions. Our research, in our view may be useful as there is a lack of information about diseases of fish in natural reservoirs, in particular in the Soligorsk reservoir and the knowledge of the cycles of changes in the number of parasites helps to work out a forecast of their mass appearance and the time necessary to combat them as well as realistically estimate the state of ichtyofauna and the prospects for its development. | ||||
