Abstract

The present work deals with the study of population dynamics of Circumoncobothrium Sp. Shinde, 1968 and Senga Sp. Dollfus 1938, from Mastacembelus armatus from different places and fish market at Aurangabad and Beed region for the period of one annual cycle (July 2021 to June 2022). The percentage of incidence, intensity, density and index of infection is recorded along with the influence of seasons on these values during study period.

Introduction

I. INTRODUCTION

Teleost fish plays a central role in ecosystems as consumers in food chains, and because they offer a large surface area for encounter and colonization. They are frequently utilized as hosts by range of parasites that are taxonomically diverse and that exhibit a wide variety of life cycle strategies. The invasion of parasitic infection affects nutrition, metabolism, and the secretory function of the alimentary canal (Markov, 1961). It also harms the neurological system. Stress is a result of unfavorable environmental factors, which also erode immunity and make a person more susceptible to diseases (Eissa, 2002). The research of helminth parasite variety and distribution began in India in the middle of the 19th century, and multiple works have been completed in various regions of the country by Bhalerao, 1937; Gupta, 1984; Soota, 1981; Sood, 1989; Tondon et al., 2005; Pandey and Agrawal, 2008; and Deshmukh, 2015. The distribution of helminths is not only affected by seasons but also by host age, size, diet, abundance of fishes and an independent number of parasites within the fi sh. Change in climatic conditions is predicted to affect the prevalence of parasites in freshwater and marine ecosystems. A study of Chubb (1977) showed the seasonal occurrence of helminthes of freshwater fishes from different climatic zones. Parasitic disease have posed a complex problem and has become a great challenge to the parasitologists in the world today, coupled with the rapid changing world; the changes in the human ecology and the effect of climatic changes on parasitic system have further increased the threat to human as well as animals life.

The studies on Population dynamic of fish parasites with respect to the fluctuation of the entire parasites fauna of any host species are still meager. The majority of these investigations have been carried out in seasonal cycles. Seasonal environmental changes of water affect occurrence of parasites of aquatic host (Dogieal et al., 1970).

The population dynamics, incidence of infection and seasonal variation of helminth parasites to the host particularly fish, the following literature is available: Hiware (2007), Chubb (1977), Forbs et al., (1989), Anderson (1976), Dobson (1985), Dogiel (1958), Esch (1977), Lawerence (1970), Thomas (1964), Satpute and Agarwal (1974), Firdaus (1988) and carried out work on different aspect of parasites. According to Kennedy (1976), the study can be used as the biological of method to regulate population of parasites.

II. MATERIAL AND METHOD

The hosts Mastecembelus armatus were collected from the local markets of Aurangabad and Beed district of Marathwada region with more or less regular periodicity, brought to laboratory, autopsied and examined for cestode infection for a period of one annual cycle July 2021 to June 2022. The parasites were collected washed with saline solution and preserved in 4% formalin, some were processed for taxonomic study: stained with Harris Haematoxylin stain, dehydrated, cleared in xylene, mounted in DPX and identified. The data obtained throughout the year was processed scrutinized and analyzed to derive the various biostatical parameters such as incidence, intensity, density and index of infection by using following formulae.

                                                    Infected host × 100

The % incidence of infection = -------------------------

                                                    Total host examined

 

                                                   No of host infected

Intensity of infection               =-------------------------

                                                   No of host infected

 

                                                   No of host infected

Density of infection               =-------------------------

                                                   No of host infected

 

                                                    No of host infected × No of parasites collected

Index of infection                   = -----------------------------------------------------------

                                                    No of host (infected + uninfected) examined

The collected parasites after closer taxonomic observation turned out to be the genus Circumoncobothrium and Senga

The values for the percentage of incidence , intensity, density and index of infection for Circumoncobothrium Sp. Shinde, 1968 in Aurangabad and Beed district is shown in Table 1  2, and Senga in Table no 3, 4.

Table no 1 shows the values for the percentage of incidence, intensity, density and index for Circumoncobothrium Sp infecting Mastacembelus armatus in Aurangabad dist, were it revealed that the incident of infection was highest (62.50%) in the month of October 2021, whereas the value was lowest (11.11%) in the month of January 2022, during the remaining month it was ranging from 20.00% (March 2022), 25.00% (September 2022) and 37.50% (October 2022). The incident of infection in the month of December was totally absent. The value for intensity density and index of infection was very high during the month July 2022, but intensity of infection it was low than the month of September 2022, whereas lowest during July 2021.

Hiware and Pawar (2007) observed the incidence of infection highest in rainy season and moderate in winter season, incidence of infection was lowest in summer season in Gangesia Sp. and Protocephalus Sp.

According to Fartade and Chati (2016) high incidences, intensity, density and index of infection of all the helminth parasites occurred in summer season followed by winter season where as lower infections in monsoon season .The intensity varies greatly with respect to helminth parasites and host species, host size and feeding habitats, season and locality.
