Relative condition factor and fulton’s condition factor of the fresh water cyprinid amblypharyngodon mola (ham-buch) from assam

The Fulton’s condition factor (K) and relative condition factor (Kn) of the cyprinid Amblypharyngodon mola collected from the culture ponds of Jorhat district, Assam was studied during July 2010 to June 2012. The study was carried out in relation to various length groups and different months of the year. The regression coefficient ‘b’ computed from the length-weight data of 260 females and 310 males was 2.846 for male and 3.286 for female. The values of ‘K’ fluctuated between a minimum of 0.824 and maximum of 1.039 for males, while for females, the values were between 0.879 to 1.184. On the other hand, the ‘Kn’ values showed variation between 1.315 to 1.943 in male and 1.642 to 3.473 in females. The high average ‘Kn’ values and ‘K’ values recorded for all the months indicated good condition of the fish.
