The study explores the Ichthyofaunal diversity of freshwater Cyprinidae fish in the Panjkora River of Dir, Khyber Pakhtunkhwa, Pakistan. A total of 911 fish samples were collected from 5 different sites along the river and identified using standard identification keys. Out of the 911 fish samples, 204 were related to family Cyprinidae, having 4 sub families, i.e Cyprininae representing 3 species i.e Carassius auratus, Cyprinus carpio, Cyprinus watsoni, Danioninae representing 6 species i.e Barilius modestus, Barilius vagra, Barilius pakistanicus, Amblypharangodon mola, Salmophasia punjabensis, Rasbora daniconius, Labeoninae representing 5 species i.e Tor putitora, Crossocheilus diplocheilus, Gara gotyla, Labeo rohita, Labeo diplocheilus, and Barbinae representing 6 species i.e Puntius ticto, Puntius sophore, Puntius chonchonius, Schizothorax esocinus, Schizothorax labiatus and Schizothorax plagiostomus. This study adds 6 new species i.e Amblypharangodon mola, Salmophasia punjabensis, Labeo rohita, Labeo diplocheilus, Puntius chonchonius and Rasbora daniconius for the 1st time which are not reported earlier. EXCEL 2019 and XLSTAT were used for principal components analysis to study richness and correlation of fish diversity. Eigenvalues obtained from Sheringal to Zulam are 3.72, 0.511, 0.37, 0.29 and 0.09 respectively. The higher eigenvalue of Sheringal site shows higher diversity. Water quality study shows that the mean values of water temperature was 16.8°C, pH 7.08, total hardness134.6 mg/L, alkalinity 89.3 mg/L, Nitrate 5.93 mg/L, Chlorine 0.87 mg/L, Nitrite0.02 mg/L and Copper 0.04 mg/L, Iron 0.07 mg/L, Lead 0.002 mg/L. The physicochemical parameters of river Panjkora during the study time remained within the permissible limits as prescribed by the WHO (2005). Gut analysis revealed the presence of algae, nymphs insect’s larvae, macroinvertebrates and protozoans.

“…Their main food items included were detritus, insects, insect larvae, small fish, seeds, mud, Chironomus larvae and caddis fly larvae, nymphs of dragonfly, mayfly, daphnia and body parts of dead animals. Research on feeding habits supports findings from studies by Jan et al (2018), Kausar and Salim (2006), Hajisamae et al (2003), andPiska et al (1991). Insects, diatoms, algae, and planktons have all been found in guts of fish and the surrounding water.…”

This study was designed to assess the ichthyofaunal diversity of River Panjkora, Khyber Pakhtunkhwa, Pakistan. For this purpose, a total of 1189 fish from six different sites were collected along the river and identified using standard keys. The fish collected and identified were representing 38 species, belonging to 7 families. The investigation spanned a year, from July 2021 to May 2022. The most dominant family was Cyprinidae 76% (n=906/1189), followed by Nemacheilidae 5.8% (n=69/1189), Channidae 5.2% (n=62/1189), Sisoridae 5.1% (n=61/1189), Mastacembelidae 4.9% (n=58/1189), Salmonidae 2.6% (n=31/1189) and least was Bagridae 0.17 (n=2/1189). The most abundant speices was Schizothorax plagiostomus with relative density of 16.8. Family Cyprinidae was represented by 21 species, Sisoridae by 7 species, Nemacheilidae by 5 species, Channidae by 2 species, while Bagridae, Salmonidae and Mastacembelidae, were each represented by a single species. PAST 3, XLSTAT and EXCEL 2019 were used for principal component analysis to study correlation of fish diversity and richness. Eigenvalue obtained from Kumrat to Busaq were 3.32, 1.01, 0.80, 0.44, 0.31 and 0.10 respectively. The higher value at Kumrat shows higher diversity. The water quality assessment showed average value of water temperature 10.4 ͦC, pH 7.0, electrical conductivity 184 mg/L, dissolved oxygen 7.9 mg/L, turbidity 43.73 mg/L, total dissolved solids 101 mg/L, total suspended solids 34.72 mg/L, total solids 135.53 mg/L, total alkalinity 75.77 mg/L, total hardness 58.37 mg/L, ammonia 0.46 mg/L, sulphate 26.03 mg/L, chloride 14.67 mg/L, calcium 69.11 mg/L, chromium 0.18 mg/L, copper 0.03, cobalt mg/L 0.04, nickel 0.039 mg/L, lead 0.02 mg/L and Zinc 0.35 mg/L. The findings of this study indicated that most of the physicochemical parameters remained within the acceptable limits throughout the study period. Analysis of fish gut contents included; nymphs, insect larvae, the presence of algae, protozoans and macroinvertebrates in the river ecosystem.

“…Relative fecundity decreases with an increase in body weight (Wagle, 2014), and that the variation in the fecundities among the fishes of the same as well as different species are affected by their size, age, condition, food intake and space (Jan and Ahmed, 2016).…”

Neolissochilus hexagonolepis (McClelland, 1839) is one among the notable species in snow-fed torrential rivers of Nepal. The present study attempts to investigate some reproductive traits of N. hexagonolepis, including the length at first maturity, fecundity and its relationships with biometric variables like lengths (TL, SL, and FL) and weights (TW and OW) of the fish in the mid-reaches of Tamor River, Nepal. A total of 109 fish samples were collected from the river. For each individual, total length (TL), standard length (SL) and fork length (FL) were measured in a fully stretched condition to the nearest 1mm using a measuring tape and graduated ruler, while total weight (TW) and ovary weight (OW) was measured using a digital balance with the precision of 0.01 g. The mean absolute fecundity (F) was 8356.44 ± 4612.59 and ranged from 2398.6 to 20160. SL was more significantly correlated with absolute fecundity (R2=0.59; p<0.001) than other body metrics. The results showed that female individuals of N. hexagonolepis attained the first sexual maturity at TL 32.9 cm. N. hexagonolepis exhibited a protracted breeding period with its ovaries passing through six different stages of maturation. The finding of the present study may serve as a protocol for fishery biologists and managers to promulgate adequate regulations for continual fishery management in the River Tamor, Nepal.
