Length-weight relationship: eight species of Cyprinidae from river Panjkora, Khyber Pakhtunkhwa, Pakistan

Abstract

Seven hundred and twenty four fish specimens were captured from March to September 2016. The materials used in the current study were cast nets, hand nets. Eight cyprinid fish species were studied for their length-weight relationships. Parameter b in the LWR was 3.03, 3.06, 3.02, 2.29, 2.82, 3.43, 2.73 and 2.47 for Schizothorax plagiostomus, Schizothorax esocinus, Racoma labiata, Tor putitora, Barilius vagra, Garra gotyla, Puntius ticto and Arassius auratus respectively. Current study is the first attempt on the LWRs of cyprinid species, provide a baseline approach for conservation and /management of local fish fauna of economic importance.

“…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).…”
