Biodiversity and Length-Weight Relationship of Rohu (Labeo rohita) and Silver Carp (Hypophthalmichthys molitrix) in the River Indus, Pakistan: A Healthcare Context

Abstract

The primary aims of this study are to assess the biodiversity and establish length-weight relationships for two economically important fish species, namely silver carp (Hypophthalmichthys molitrix) and Rohu (Labeo rohita), in the Dera Ismail Khan region of Pakistan. Throughout one year, a comprehensive sampling approach was employed to collect data on fish populations inhabiting the River Indus and its adjacent aquatic ecosystems. To get comprehensive data on the distribution and population size of the species, a combination of traditional fishing equipment, such as gill nets and cast nets, and non-intrusive methods of data collection was employed. The findings of this study indicate that the River Indus exhibits a notable level of biodiversity, with the silver carp and Rohu species emerging as prominent members of the fish community. The development of length-weight relationships for both species, utilizing a range of size classes, will prove valuable in monitoring their growth and assessing their overall well-being within the ecosystem. The comprehension of the fish diversity and population dynamics of Rohu and Silver Carp has significant importance in Dera Ismail Khan. Moreover, the study's findings about the relationships between length and weight can serve as a valuable resource for conservation and fisheries management efforts. This, in turn, can contribute to the promotion of sustainable resource utilization and the preservation of the invaluable aquatic ecosystem under consideration.
