Abstract: The present paper studies the length - weight relationship and condition factor of Penaeus monodon landed at Digha coast, West Bengal, India during 2011-2013. A total of 633 numbers of P. monodon were examined of which 391 were females and 242 were males. The length – weight relationship of P. monodon; males, females and combined were: W=0.076636L2.40936, W=0.026828L2.38872 and W=0.018629L2.60916. Length-weight relationship revealed the exponent ranging from 2.245 to 2.572 for males, 2.287 to 2.489 for females and 2.525 to 2.692 for combined sexes, respectively. Growth exhibited negative allometry for both with mean exponents b = 2.245 for males, b = 2.793 for females and b = 2.60916 for combined sexes. Highest average condition factor observed was of 1.5 in July of males and 1.7 in January of females and lowest of 1.2 in March of males and 1.4 in Feb, March, Aug and Sept of females.
