“…Length weight relationship was studied for the various specimens of fish Wallagu attu [27] . Further, there were several previous studies which defined the different morphometric parameters of Wallago attu and their associations [2,26] . Finally, the morphometric parameter values enhanced with an augmentation in the total length of fish Mystus aor.…”

The present study aimed to investigate the morphometric characters of fish species, Labeo rohita, Rita rita, Wallago attu and Mystus aor sampled from two aquatic habitats, Gomti River nearby Lucknow and Ganga River at Ghazipur, Uttar Pradesh, India. Both rivers are extremely cherished rivers as they are full of natural resources and highly rich in faunal and floral diversity. A total of 100 specimens of each fish species were collected during October, 2021 to January, 2022. The seventeen morphometric parameters were selected for the comparative differential analysis of population stocks of each fish species in two aquatic habitats. The quantitative measurements of all the morphometric characters delivered the important information about the growth of body parts of fishes in different aquatic ecosystem. The variations in morphometry of individuals of a species illustrated the alterations in the population status under the differential environmental circumstances. The approach of morphometric analysis can be a strategic tool to explore the body shape formation of fish species in different ecosystems. The analyzed data of morphometric dimensions of four fish species would be beneficial for the policy makers or planners to develop the scientific strategies for their protection and conservation. The findings will also set the scientific principles for the management and sustainable development of the commercially essential freshwater food fishes.

Fish are cold blooded vertebrates’ identification on the bases of morphology is not more precise and required high taxonomic expertise therefore molecular identification is used as an alternative and more accurate technique for the identification of fishes. In the current investigation 39 fish specimens were collected from May 2021 to February 2022. With this aim, the recent study was conducted in the freshwaters of River Swat in Malakand Division, Khyber Pakhtunkhwa, Pakistan to explore the genetic diversity of genus Triplophysa. DNA was extracted and amplified using gene specific primers. The PCR products carefully were sequenced and Phylogenic analysis was performed using neighbor-joining, maximum likelihood through MEGA software. Nucleotide composition and genetic pairwise distance recommend that the calculated species of the subfamily Nemacheilinae are organically dissimilar. The River Swat is the study area and it is inhabited by three Triplophysa species, Triplophysa naziri, Triplophysa microps, and Triplophysa choprai. The evolutionary tree shows that these species are clearly separated. The mean of total length calculated in the three species of the genus Triplophysa such as 8.175 ± 0.198 cm for Triplophysa naziri, 10.14 ± 0.35 cm for Triplophysa microps, 11.052 ± 0.23 cm for Triplophysa choprai. This study provides a model for the improvement of identification in cryptic diversity and field of ichthyofauna.

“…(Hassan et al,2020a).The research of finfish gives an idea for providing a fruitful product to aquaculture and plays an important role in fisheries development (Hassan et al, 2021b). Fish diversity traits, abundance, and population are influenced by breeding grounds, food availability, geological and geographic factors, physiochemical parameters, size, depth, water current and topographic characteristics (Attaullah et al,2021).Fish are susceptible to ecological modifications, and their diversity in a broad spectrum of differential tolerance reflects the health status of the ecosystem (Chowdhury et al, 2019;Sabbir et al, 2020). Changes in ecosystems of the food tropical level implanted remarkable effects on the abundance and distribution of fish.…”

This study was conducted to estimate the diversity and the occurrence of commercially important finfish species collected by twenty fish sampling site of Sindh and Baluchistan coasts of the Arabian Sea in Pakistan from January to December 2019. Additionally, physicochemical characteristics of seawater were analyzed from these selected sites and found to be within suitable ranges required for fish growth and survive. A total of 81287 fish individuals were collected and identified as 49 species belonging to 26 families in our study. The most diversified family was Sparidae (13 species) followed by Carangidae and Lutjanidae (4 species), Mullidae, Serranidae, Ariidae (3 species), and Sciaenidae (2 species). The remaining 20 families were represented by only one species. The values of Shannon diversity index calculated for the four selected habitats revealed that high fish diversity was reported at Sonmiani Coast (H'=1.81), while less at Ormara Coast (H'=0.23). Likewise, Evenness index (E) was high at Sonmiani Coast (E=0.50) and less fish diversity was reported at Ormara Coast (E=0.06). Reducing risks to threatened marine species in coastal habitats also requires conservation actions at multiple scales. Thus, it was concluded that our study could be valuable in providing the more information’s regarding to the diversity of finfish species and their occurrence along the Pakistan Coast. Further, to better understand the effects, regular monitoring and conservation measures should be taken to mitigate the influence of anthropogenic activities and protect finfish diversity from further decline
