Shrimp farms were selected along the Kendrapara coast, Odisha. The area of each experimental pond was 0.2ha. The experiment was conducted during the period from March, 2016 to June, 2016(120 days). The experiment was designed on completely randomized design (CRD) having 3 treatments, each with three replications. 13 days old PL of Penaeus monodon were collected from hatchery and acclimatized for a week in laboratory condition before stocking in pond. In the treatments (T1, T2 and T3), tiger shrimp was integrated with Gracilaria verrucosa, whereas ponds without seaweed was served as control. The tiger shrimp and seaweeds were stocked at densities of 5pc & 2 kg/m2, 5pc & 2.5 kg/m2 and 5pc & 3kg/m2 for the first, second and third treatments respectively. In culture ponds it was 23.61 ±3.20g (T0), 26.63±3.15 g (T1), 33.26±5.60g (T2) and 29.91±4.82 g (T3). Statistical analysis indicated that there was a highly significant difference in the average body weight between integrated model and control pond (p< 0.05). Growth performance of shrimp pond integrated with Gracilaria verrucosa was higher than the shrimp of control pond. This could be achieved due to the efficacy of seaweed to maintain good water quality by reducing ammonia content and increasing dissolved oxygen content.
