Prevalence of rhabdochoniasis in snow trout of river Swat and river Panjkora, Khyber Pakhtunkhwa province, Pakistan

Abstract

This research was aimed to explore the helminth parasitic diseases in Schizothorax plagiostomus (the snow trout) from river Swat and river Panjkora, Pakistan. Collection of 360 fish specimens have done from the lower, middle and upper reaches of both the rivers through gill nets, cast nets, dragon nets and hooks. All the samples were examined in the University of Malakand, Zoology Department for helminth parasites during the months from January 2015 to December 2016. Of the total examined fish samples 21.9% (n=79) were infected with Rhabdochona spp including 17.7% (n=32/180) in river Swat and 26.6% (n=47/180) in river Panjkora. Highest month-wise prevalence (p=0.09878,p<0.05) was reported in May (30%), then by February and October each (26.6%) while the lowest during August (13.3%). Highest prevalence (p=0.9723, p<0.05) was reported in summer season (26.6%), while lowest in the winter season (20%). Adults were highly infected (p=< 0.0001) in prevalence (63.7%) followed by sub-adults (13.2%) while no infection was found in juvenile specimens. Females fish samples had higher (p=0.0277, p>0.05) prevalence (28.8%) than males (16.6%). Fishes of the lower reaches had highest (p=0.0029, P>0.05) prevalence (31.7%) followed by middle reaches (16.5%) while the lowest prevalence was observed in samples of fish collected from upper reaches (9.87%). Present study address that Rhabdochona spp in the intestine of snow trout has a long term relationship and call as a natural infection in cyprinids and zoonotic risk to human.

A comprehensive model for the implementation of agricultural land levelling and consolidation plan in the Abu Fazel region of Ahvaz

“…This type of fragmentation is an obstacle to the rational and optimal use of land and other production factors and reduces the efficiency of the entire activity in a geographical area. The second type is the fragmentation of the lands of each owner in distant and often small parts, which also adds to the first type and as mentioned by studies such as Khan et al (2022) leads to the aggravation of the whole situation. Such an arrangement of agricultural lands which is not a new phenomenon and not specific to Iran, has been formed under special conditions and has had positive functions.…”

Assessments of some trace metals in water samples of nursery pond of Grass Carp (Ctenopharyngodon idella, Valenciennes, 1844) in Bannu Fish Hatchery of Khyber Pakhtunkhwa, Pakistan

“…Though, due to the introduction of these carp fish cultures in the last few years, fisheries and aquaculture practices had now become a part of economics that contribute efficiently to fish food production in both government and private sectors (Yousafzai et al, 2010;Cudmore et al, 2017). Some of the economically important fish species of the region have been studied recently (Ahmad et al, 2020;Khalid et al, 2020;Khan et al, 2021a;Khan et al, 2021b;Khan et al, 2021c;Khan et al, 2021d;Shah et al, 2021;Ullah et al, 2021).…”

“…Rhabdochona spp. in the intestine of snow trout has a long term relationship and is considered as natural infection in cyprinids and zoonotic risk to human (Dujardin, 1845;Railliet & Henry, 1916;Khan et al, 2022).…”
