Seasonal effect of helminth parasites on freshwater fishesPaperback, 24 May 2018

Health of any population depends on the control of disease and maintenance of a healthy relationship between living creatures and their environment. The parasitic infection is greatly influenced by the season, which basically interferes with ecology and physiology of the fish. The characteristic of any water body can influence and determine its parasitic fauna and on favorable environmental conditions, such as water, food and temperature become favorable for mass reproduction of parasites, the disease may spread very quickly. Different climatic condition variables have their direct influence on freshwater fish physiology as well as helminth parasitic abundance. Seasonal variation not only affects the parasitic prevalence but also regulate parasitic infection intensity in freshwater host fishes and their invasive tissues. Helminth parasites invasive cause diseases that affect the normal health conditions and cause reduction of growth, abnormal metabolic activities and even death of the freshwater fishes thus results great economic loss.
