Abstract :The present study was carried out to assess the reproduction weight-length based growth and condition factor of Holothuria arenicola Semper, 1868, from January to December 2018, in Karachi coast, Northern Arabian Sea. The sex percentage was determined as 33.3% females and 66.7% males. Length of specimens ranged from 14 and 38 cm and weight of specimens ranged from 21 and 82 g. The relationship was  W = 2.408 L 0.9482 insert ignore into journalissuearticles values(R 2 = 0.999); for females, W = 0.989 L 0.9482 insert ignore into journalissuearticles values(R 2 = 0.998); for males and  W = 1.234 L 1.1565 insert ignore into journalissuearticles values(R 2 = 0.999); for all individual. The condition factor ranged between 0.84 and 2.62 insert ignore into journalissuearticles values(mean: 1.52±0.70); in females and between 0.83 and 2.67 insert ignore into journalissuearticles values(mean: 1.43±0.71); in males. The gonadosomatic index of specimens ranged between 5.50 and 10.66 insert ignore into journalissuearticles values(mean: 7.95±1.24);. The gutted weight of specimens ranged between 2.10 and 11.44 g insert ignore into journalissuearticles values(mean: 4.91±1.77);. Studies about environmental variables and characteristics are necessary in order to complement the understanding of reproduction, the length-weight relationships and condition of sea cucumber in Karachi coast.
