| Growth and Mortality Parameters of Cyprinus carpio were studies in Shadegan wetland. Monthly samples were collected from landing at five stations: Doragh, Rogabe, Khorosy, Salmaneh, Atish. During one year's study from April 2013 to March 2014, 1401 specimens were measured. Mean±s.d length values for this female, male and total fish include were 207±20, 200±33 mm respectively and mean±s.d weight Values were 162±98, 116 ±96gr respectively. Length-weight relationship with Excel program of for female, male this species were resulted W=0.00003 L2.89 (N=397, R2=0.91), W=0.0004 L2.60 (N=301, R2=0.95) respectively. The growth parameters of von Bertalanffy equation for female, male and total fish this species as below were estimated as, The growth parameters of von Bertalanffy equation were estimated as, L∞: 514, 483 and 514 and K: 0.31, 0.49 and 0.36 and t0: -0.5,- 0.15, and -0.2 respectively. Mortality coefficients such as total mortality, Z: 1.41, 1.51 and 1.44 natural mortality, M: 0.61, 0.83 and 0.66 and fishing mortality, F: 0.53, 0.67 and 0.83 respectively. Based on results and with comparing to American Fisheries Society (AFS) indices, this species was classified as moderate vulnerable group fishes. |
