A total of nine morphometric measurements (Total length, Standard length, Fork length, Body depth, Head Length, Pre-dorsal fin length, Pre-pelvic fin length, Pre-pectoral fin length, and Pre-anal fin length) and body weight were noted. Basic descriptive statistical analysis and correlation coefficient (r) were analysis with total length (independent variable) and other morphometric measurements (dependent variable). The result presented that except pre-pelvic fin with total length in (Labeo rohita and Cyprinus carpio) and pre-dorsal fin with total length in (Cirrhinus mrigala and Catla catla) others all morphometric dimensions are highly correlated with total length. Also the regression coefficient (b) was less than 3.0 which indicated that all other morphometric dimensions compared with total length shows negative allometric growth and the body weight with total length shows positive allometric growth in (Labeo rohita = 3.260), negative allometric growth in (Catla catla = 2.100 and Cyprinus carpio = 2.400) and isomeric growth in (Cirrhinus mrigala = 3.016). The study represent that aquatic environment of Jinnah Barrage is appropriate for the growth of fishes. Keywords: Morphometric relationship, Jinnah barrage, cyprinidae 1. Introduction Fish is one of the diversified and most essential fundamentals that play a vital role in the wealth of many nations as they have been found a constant item in the diet of many nations [ 1 ]. The family cyprinidae are the most widely spread freshwater fish family and are native to Asia and Europe. In India freshwater fish fauna cyprindae are one of the important components which plays a central role within the freshwater ecosystem. Some of the species have a role as ornamental species; some are used as food species and many of them have medicinal value and for extracting oil [2] . The morphometric measurements in fishes are the most important for describing the allometric growth and relationships with the body length [3] . For ichthyo- taxonomical studies, morphometric dimensions are largely being used to segregate many fish species [4-6] . They are measurable features which are helpful for separating closely related genera, species and even populations within them [7] . Morphometric study is an important tool for measuring discreteness of the same species and is helpful to classify and identify the fishes [8] . These characters are important for easy and correct recognition of all fish species in laboratory as well as its natural habitat [9] . The study of fish morphometry is not only important to know the taxonomy but also the fitness of fish species. The structure and shape are exclusive to the species and the changes in its character are possibly related to the habit and habitat among the variants of this species [10] The current study had been undertaken with the main objective of the study is to observe the morphometric relationships of some important species of the family Cyprinidae in Jinnah Barrage which will provide info about the growth and habitat. 2. Materials and Methods 2.1 Study area specification The present study focuses on Jinnah Barrage (32.9201° N, 71.5191° E) tributaries of the Indus River. Jinnah Barrage (Figure 1) is located about 5 km away from the Kalabagh town in district Mianwali. Mianwali is situated in province Punjab (Pakistan) and is almost 200 m above the sea level. The construction on the barrage was begun in 1939 and was completed in
