- SEASONAL DISTRIBUTION AND POPULATION STRUCTURE OF P. fusiformis (DIGENEA: BUCEPHALIDAE) IN E. vacha IN KAPTAI LAKE, BANGLADESH ABUL K. BASHIRULLAH A.K.M. HAFIZUDDIN Multidisciplinaria (Ciencias Naturales y Exactas) vacha fi sh trematode Bangladesh fresh water The seasonal prevalence, abundance, mean intensity, and population structure of P. fusiformis (Digenea: Bucephalidae), a parasite found in E. vacha, a fresh water fi sh in the Kaptai Lake, Bangladesh were studied for two years. A total of 208 fi sh were examined and 17,300 trematodes were recovered from 182 infected fi sh. The inter-annual prevalence and mean intensity of P. fusiformis were signifi cant, and increased as the host’s body size increased. The parasites were found throughout the year. The largest number of trematodes wERE found in the summer period, followed by that of winter, indicating seasonality. The overall prevalence and mean intensity were 83.6% and 68.4 for the fi rst year and 91.3% and 119.78 for the second year, respectively. The intensity and abundance fl uctuated over the study period and were statistically signifi cant. Both immature and mature adult worms occurred throughout the year. No statistical association was observed when the occurrence of parasites at both stages of maturity was contrasted against temperature, pH, or dissolved oxygen of the lake or rainfall. 2007 artículo científico 1315-0162 https://www.redalyc.org/articulo.oa?id=427739433003 es http://www.redalyc.org/revista.oa?id=4277 SABER.
