IN PAKISTAN IT HAS BEEN ACCOUNTED FOR AS LOWER HAZARD CLOSE UNDERMINED AND IN BANGLADESH AS JEOPARDIZED SPECIES(CAM1998)(IUCN BANGLADESH2000).
Fisheries are a standout amongst the most critical wellsprings of income and financial industry of our nation and fills in as an essential sustenance division in human nourishment (dwivedi et al., 2009).
N OUR NATION, LABEO CALBASU (KALBASU) IS A ONE OF INCREDIBLE BUSINESS IMPERATIVE SPECIES TAKING AFTER THREE OTHER INDIAN REAL CARPS, FOR EXAMPLE, CATLA, ROHU AND MRIGAL.
LABEO CALBASU (KALBASU) UNDERPINS AN ESSENTIAL BUSINESS FISHERY IN THE STREAMS GANGA (SINGH ET AL., 1998), YAMUNA (GUPTA AND TYAGI, 1992), GHAGHRA (DWIVEDI ET AL., 2004) AND CENTER STRETCH OF KEN (NAUTIYAL ET AL., 2004) AND INDUS WATERWAY PAKISTAN. FISH POPULACE IS AN INEXHAUSTIBLE SOURCE ON THE OFF CHANCE THAT THEY ARE ABUSED IN AN ARRANGED WAY.
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.(TALWAR ,PK AJ;LD RAN A.G.,1991 ET AL).
Fishery sciences, length weight connections give measurements which is foundation in research and administration and are real apparatuses for exact estimation of biomass and computation of length recurrence tests to add up to get (d. Pauly and f. C. Gayanilo, 1996).
Dorsal profile is more arched than of abdomen.Lip thick,fringed.
2pairs of barbells,rostal match longer than maxillary pair.(Raham,1989).
No pores on snout.Eye arranged somewhat front from the half of the head.(Bhuiyan, 1964).Caudal peduncle is short.Lateral line well marked.Scales direct in estimate.
There are 20 pushes round the caudal peduncle (Bhuiyan, 1964). Mouth is decently wide and inferor.Gill openings wide and gill rakers are villiform, short and weak (Bhuiyan, 1964).
Shading dull dark however the ventral part light dark.Ventral bit of the opercular locale is white.Iris coppery.This angle accomplishes a length of 90cm (Talwar and Jihingran, 1991).

Shading dull dark however the ventral part light dark.Ventral bit of the opercular locale is white.Iris coppery.This angle accomplishes a length of 90cm (Talwar and Jihingran, 1991).Maxium detailed size for this fish of Labeo Calbasu 90.0cm(Day,1878) by amid the most recent couple of decades this size has not been accounted for.In life,blackish-green,lighter beneath flanks buff pink or with red spots with dull edges which may shape fishes.Fine dark upper flap of caudal balance normally tipped with white.For the most part it is a scavenger. It encourages on vegetable issue, green growth, shellfish, bugs, hatchlings diatoms Mud and sand and so on.Fertility of this species runs in the vicinity of 193,000 and 238,000 (Rahaman 1989).Breeding is utilized to begin before the finish of May with the beginning of south west storm and proceed till the finish of October (Chacko and Kurian 1949).It is a freshwater angle animal types; for the most part occupies Rivers. By and large, happens in Rivers and Ponds, likewise in normal Lakes, stores, streams and trenches (Bhuiyan 1964, Chondar 1999, Riede 2004, Rahman 2005).
Its most loved environment is the profound pools of Rivers, where it to a great extent stays confined amid the winter and summer months, and climb to adjoining shallower locale of the waterway for reproducing amid rainstorm months (Chondar 1999). It can be raised in lakes and tanks (A.L. Bhuiyan,1964) (A.K.A. Rahman 2005).It can endure marginally salty water too.Labeo calbasu (Hamilton) is a broadly conveyed real carp possessing the majority of the southern districts of Asia including India, Pakistan, Bangladesh, Myanmar, Nepal, Thailand and South-Western China.This species happens in waterways and ponds.(Talwar ,PK aj;LD ran A.G.,1991 et al).Wide conveyance in Pakistan, It is an imperative nourishment fish.At a few spots is alluded to as the BLACK RAHU.”
It is a mainstream nourishment angle having great taste.Less intramuscular bones and high protein content.It appreciates a decent game fish.It is a critical diversion angle in the tanks where it is supplied and is developed alongside different species.There is an extremely regular fish all through India and neighboring countries.Howerever populace patterns are not known. (IUCN 2010 red book of debilitated fishes)(Juffe Bingoli,D.,Rema Devi,K.R.,Datta,N.C and Choudhry, S).Accessible in Barnai River yet recorded in IUCN RED LIST as debilitated (IUCN 2,000).Public mindfulness develop and quit angling strategy for protection of the species.An inadequate writing of length weight examination exists on significant carps of Asian nations so there was have to work and break down length weight connections increasingly and simple cultivable fishes; i.e. carps keeping in mind the end goal to address the nourishment shortage difficulties gave by fast urbanization and over populace.
Among more inexhaustible carps in Asia Labeo calbasu is nourishment critical teleost occupying in different range including Pakistan, India, Myanmar, Yamuna, Thailand and Bangladesh. Amid the mid 1980’s, Labeo calbasu was an incredible business vital animal types taking after three other Indian Major Carps, for example, Catla (Gibelion catla), Rohu (Labeo rohita) and Mrigal (Cirrhinus mrigala), despite the fact that fish ranchers lost enthusiasm because of the inaccessibility of seeds either characteristic or counterfeit sources.
It is a standout amongst the most critical reasons for this species is going to achieved undermined level in freshwater biological community. Not just that the above said explanations behind undermined state, are additionally wide varieties in water stream amid different seasons for essential swing down to decide the status of this species (Chakraborty BK, Mi 2006).
Fish populaces are regular control forms that persistently alter with change structure, wealth and extensive variety of components.
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 (Chakraborty BK, Mi 2006
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 (Arunachalam M, J.A Johnson 2003).
Be that as it may, the fish gathering structure and capacity are additionally fundamentally connected with geographic variety and understanding the example is urgent compelling evaluation, observing of streams and waterways (Arunachalam M, J.A Johnson et al., 2003).
Season as an outcomes in oss of future fish stock, unlawful angling strategies viz. harming, grenadine and dynamiting. Until now, these angling strategies are causing to harm for angle populace, as well as even fish eggs, hatchlings and fish sustenance creatures are fell.
In this manner, it is the time, to find a way to monitor the types of our riverine angle biomass and to reestablish their living space (Arunachalam M, J.A Johnson 2003).
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 (Day, 1878) 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 (T. P. Morato, P. Afonso2001) (O. Özaydin and E. Taskavak 2007).
Length weight connections are great markers of largeness and fish condition (E. D. Le Cren, 1951).
