Abstract:
Cirrhinus mrigala (bilaterally symmetrical and stream lined) and Cyprinus carpio (European carp, formerly known as the common carp) both species belongs to class: Actinoptergii, Family: cyprinidaeis, they are important fish species of river Indus and as belongs to family cyprinidae and is a warm water fish so also found in reservoirs, lakes and also Pools. The present study aimed to describe the morphometric ratios of Cirrhinus mrigala and Cyprinus carpio to find out the variation and relationship between different body parts of fish Cirrhinus mrigala and Cyprinus carpio through statistical analysis of external morphometric parameters. The aim of the current study was also to conduct the research on relationship between the selected visceral organ (Gonads) and the body weight of Cirrhinus mrigala and Cyprinus carpio (Hamilton, 1822), to determine the weight of the visceral and to find out that difference of the male and female visceral organ (Gonads) with body weight and body length of Cirrhinus mrigala and Cyprinus carpio. Sample was collected from River Indus, Dera Ismail Khan from January 2022 to May 2022. Total 30 samples of Cirrhinus mrigala and 30 samples of Cyprinus carpio were collected on weekly basis from River Indus and brought to the zoology department laboratory, Government girls degree collage no 2 Dera Ismail Khan for the measurement of morphometric characters. 18 morphometric characters and contribution of gonadal weight in the total weight of Cirrhinus mrigala and Cyprinus carpio were studied. The strongest correlation among all morphometric characters of Cirrhinus mrigala female except eye diameter (0.64*) and Total length (ED-TL), anal fin height (0.63*) and total length (AFH-TL) among all Fin height and the moderate correlation exist between the pelvic fin base lengths (0.57*) and Total length (VFBL-TL) among all morphometric characters of Cirrhinus mrigala female. The strongest correlation among all morphometric characters of Cirrhinus mrigala male is found between the head length (0.93**), Between the Anal Fin base length (0.63*) and the total length exist the weakest correlation while Moderate correlation exists between pelvic fin base length (0.64**) and total length (AFBL-TL) among all Fin base lengths and the weak correlation exist between the dorsal fin height (0.52*) and Total length (DFH-TL) among all morphometric characters xiv of Cirrhinus mrigala male. In Results of correlation Cirrhinus mrigala male I found that among eye diameter (0.47) and total length, pelvic fin height (0.48) and total length, pelvic fin base length (0.43), no significant correlation exist. The strongest correlation is found among all morphometric characters of Cyprinus carpio female. The strongest correlation among all morphometric characters of Cyprinus carpio male is found between the Standard length (0.96**) and total length (SL-TL), while Moderate correlation exists between pre-orbital head length (0.53*) and total length (POHL-TL). Only one negative correlation is found between dorsal fin base lengths (?0.45) while there exists strongest correlation of rest of the morphometric characters with total length.
