Abstract

Some factors relating to age and length were used to calculate with von berthalanffy formulae in a year from June 2008 to March 2009. In the current study, GROWTH rate and maximum length were in turn computed to 0.31 and 21.17 cm in males and 0.33 and 21 cm in female. The mean fork length of females (16-26cm) was almost the same as that reported for males (15-23.6 cm) but the length-to-weight relationships were W=0.011 * FL3.055 (males) and W = 0.024 * FL2.82 (females). Although samples did not indicate any variation in sex ratio throughout a year (p>0.05), but observed few fluctuations in different months. This study revealed differences in the life history parameters of perch compared with perch compared with other geographical regions and may be associated with lack of appropriate food condition due to the degradation of environmental conditions.
