Abstract: The tiger shrimp Penaeus monodon (Fabricius, 1798) were collected from the Government shrimp farm, Coastal Salt salinity Research Station (CSSRS), Navsari Agricultural University, Navsari, Gujarat, India during the year 2009-2010. The morphometric measurements including length and weight of 321 male, 317 female and 638 pooled population that shows 8.0-19.4 (15.257±0.070) cm, 8.0-18.5 (15.019±0.098) cm and 9.0-19.4 (15.426±0.100) cm range of length with 8.0-52.0 (30.546±.0498), 8.0-58.0 (32.760±0.541) and 8.0-58.0 (31.663±0.369) gm range of weight respectively. The regression coefficient (r²) 0.788, 0.772 & 0.780, intercept (a) -1.451, -1.620 & -1.536 and slope or regression coefficient (b) 2.478, 2.624 & 2.552 was observed for male, female and pooled population samples. The value of regression coefficient (b) was < 3.0 that shows negative allometric growth of studied population. The values of condition factor (K) was 0.537 - 1.646 (0.875±0.009) for male, 0.455 - 1.646 (0.875±0.009) for female and 0.455 - 1.646 (0.876±0.007) for pooled population which revealed that condition of studied shrimp population was almost uniform during the study period.
