The streams in pakistan are confronting various issues intended for extreme water contamination, over extraction, infringement, dams and blasts which remove the network of the waterway with its related biological communities, environmental change, deforestation in catchment regions, and so on. Labeo calbasu (hamilton) is a generally disseminated real carp possessing the greater part of the southern locales of asia including India, Pakistan, Bangladesh, myanmar, nepal, thailand and south-western china.this species happens in streams and ponds.

Other than a few factors as overfishing, species creation, populace episode, conduct, species changing from little size to expansive, biological community corruption, unending occasional variances, pesticide and sea-going contamination, sicknesses, presentation of intriguing species, decimation of reproducing grounds and unlawful angling hones. Besides, soil disintegration and rising the base making harm angle nourishment living beings, ruining of fish encouraging and reproducing grounds, owing gathering of stones and sands for development purposes, deforestation in catchment territory, crumbling the generally scattered pools once existing and shing amid this rearing season as an outcomes in loss of future fish stock, unlawful angling strategies viz. harming, grenadine and dynamiting.

These angling strategies are causing to harm for angle populace, as well as even fish eggs, hatchlings and fish nourishment creatures are crumpled. Consequently, it is the time, to find a way to preserve the types of our riverine angle biomass and to reestablish their natural surroundings.

In fishery sciences, length weight connections give insights which is foundation in research and administration and are significant instruments for exact estimation of biomass and computation of length recurrence tests to add up to get (D. Pauly and F. C. Gayanilo, 1996). The greatest detailed size for this fish is 90cm however amid the most recent couple of decades has not been accounted for.

Length weight connections help in change of development long conditions to development in weight conditions especially in angles which is a valuable parameter for ichthyologists and fish ranchers in evaluation, culture and stocking of fish.
