Comparative Growth Analysis of Litopenaeus Vannamei in Different Stocking Density at Different Farms of the Kottakudi Estuary, South East Coast of India

Abstract

Several shrimp species are being cultured in ponds, and one particular species that is gaining popularity in tropical countries is the white shrimp, Litopenaeus vannamei. The present study carried out in the Ramanathapuram district, south east coast of India. In the present study average pH recorded during the culture period was from 7.2 to 8.2 in the morning, 7.4 to 8.5 in the evening and the average dissolved oxygen was ranging between 2.3 to 7.0 in the morning and 6.0 to 8.0 ppm recorded in the evening. The temperature was ranged between 28 to 30 0C in all culture ponds maximum dissolved oxygen level in the evening. The final average body weights gained from the chendhur marine, anba aqua and subathra (35, 24.5 and 19.5 grms) respectively. In these cases, from the three different stocking density 10 m2 and 35 m2 shows the better growth.
