STUDIES ON BIOLOGY OF PERCH CHANDA NAMA (HAMILTON 1822) FROM THANA BOOLA KHAN, SINDH, PAKISTAN
Length-weight relationship (LWR), length- length relationship (LLR), relative condition factor and feeding of a small indigenous fish Chanda nama from Dau Dam Thana Boola Khan, Sindh, Pakistan are reported. A total number of 139 specimens (73 male and 66 female) were caught for this study on monthly basis from February 2015 to July 2015. Total length and standard length for each specimen were measured by measuring board and body weight (BW) of each specimen was taken by a digital balance. In male, female and total population of Chanda nama the body coefficient (b) of the LWRs indicated negative allomertic growth while LLRs were highly correlated. The value of Condition Factor was 1.21± 0.65 in male population, 1.34±0.204 in female and 1.22±0.448 in mix population which indicate the well being of fish. The fish is highly carnivorous by nature and also considered as lepidophagous (scale eater). The food of Chanda nama contained fish meat, scales, spines, insects and zooplankton.
