Abstract
Fish provides main source of high quality protein to more than one billion people in the
world. Fish parasites directly affect the productivity of fish and indirectly on human
health. This research was aimed to assess the helminth parasites in Schizothorax
plagiostomus (snow trout) of river Panjkora, Pakistan. A total of 88 fish samples were
collected from the upper, middle and lower reaches of the rivers through cast nets, hand
nets, hooks. All the collected fish samples were examined in the Parasitology Laboratory,
Department of Zoology, and University of Malakand for helminth parasites during the
months from July 2018 to February 2019.Among these fish nematodes (Rhabdochona
schizothoracis, Rhabdochona spps), trematode (Diplozoon paradoxum), cestodes
(Nippotaenia spps) and acanthocephalan (Neoechinorhynchous devdevi) were
recovered. The P value less than 0.05% (at 95% CI) was considered significant. Overall
prevalence of the fish parasites was 60.2% (53/88). The intensity of the parasite was
observed from 1.7 % to 4.61 %.Amongst these parasites highest intensity was recorded
of Rhabdochona schizothoracis (4.61%).
Highest month-wise prevalence was recorded in the month of July (90.91%), followed by
August 81.82 %( 09/11) while the lowest during February 27.28 % (03/11%). Season wise
highest prevalence was reported in summer (86.36%) while lowest in the winter season
(36.36%).This study shows that summer season is advantageous for these parasites and
affects the fish business and result in poor quality fish meat with risk of zoonotic
diseases. Adults were highly infected (82.25%) followed by sub-adults (62.0%) while no
infection was found in juvenile specimens. Female fish samples had higher prevalence
(68.22%) than males (48.22%). Fishes of the lower reaches had highest prevalence
(60.22%) followed by middle reaches (57.14%) while the lowest rate of prevalence was
noted in the fish samples collected from upper reaches 40.0%).Fish samples with
maximum length and weight were highly (76.92%) infected than small sized fish with
low body weight. Present study addresses that R. schizothoracis in the intestine of
Diplozoon paradoxum in gills of snow trout has a long term relationship and call as a
natural infection in cyprinids and zoonotic threat to human.
