Length-Weight Relationship and Relative Condition Factor of Parapenaeopsis sculptilis (Heller, 1862) from the Coastal Waters of Perak, Peninsular Malaysia

Length-weight relationship (lwr) parameters and relative condition factor (kn) of marine shrimp, parapenaeopsis sculptilis (heller, 1862) were estimated using length-weight data collected between february 2012 and january 2013 from the coastal waters of terong, perak, peninsular malaysia. the estimated length-weight relationship of p. sculptilis for both sexes was w = 0.00027tl2.80. meanwhile, the estimated relative growth coefficient (b) was 2.80 for both sexes, indicating a negative allometric growth pattern of p. sculptilis in the investigated area. relative condition factor (kn) values ranged from 0.99 to 1.064 (1.013±0.005, mean ±sd). kn value changes in various months: the highest peak was in march-april, indicating the spawning period and the trough and small peaks indicating the cycle gonadal development.
