A total of 150261 kg of different species were caught in Mahabad reservoir of which 101123.5 kg (tantamount to 67.3 % )was silver carp in the fishing season of 1998-1999. From the beginning of the fishing season, fishing effort of only active fishing cooperative were 69 times beach seine haul and for gill net with stretched mesh size of 7 to 15 cm, 2530.7 fishing effort unit (each unit is equal to 100m gillnet for 24 hours). The mean fork length and weight of Silver carp were 51.15±12.07cm and 2429±2272.1g respectively. Exponential Length-Weight relationship for this species was calculated W=0.013 L 3.04 (R2 = 97.64, n=714) which in this equation W is the total ...
