Impact of Minerals on Growth and Survival of Litopenaeus Vannamei Shrimp Culture in Low Salinity Culture Ponds

Gunalan B., B. S. Vijay Kumar

Abstract: This study examines various factors influencing the growth and survival of vannamei shrimp (Litopenaeus vannamei) across six different ponds during the culture period. Salinity levels were consistently maintained at 2 parts per thousand (ppt) throughout all ponds. pH levels ranged from 7.7 to 8.6, with dissolved oxygen remaining stable between 4.0 to 5.5 parts per million (ppm) and alkalinity varying from 138 to 170 ppm. Ammonia levels remained consistently low, while nitrite levels remained uniform. Calcium and magnesium ratios, as well as hardness levels, showed variations across ponds. Microbial colony counts fluctuated, with yellow colonies ranging from 150 to 360 and green colonies from 1 to 4. Before stocking, mineral supplementation, including calcium, magnesium, mineral mix, zeolite, and salt, was applied weekly, with specific quantities utilized. Growth rates ranged from 25 to 26.9 grams, with the highest observed in Pond A1 and the lowest in Pond A2. Survival rates ranged from 73% to 79%, with Pond B4 exhibiting the highest survival rate. These findings underscore the significance of water quality management and mineral supplementation in optimizing growth and survival rates in vannamei shrimp aquaculture.
