The mineral supplementation has been a major concern in low saline shrimp farms as many farmers are not aware of applying the actual quantity of mineral supplements to the pond waters and also there is no information on the actual release of minerals from commercial mineral supplements into the water phase. Experiments were conducted in triplicate by dissolving four commercially available mineral mixture products and four individual mineral salts separately in waters of varying salinity from 0 to 30 ppt. Controls were also run with all the saline waters without the addition of mineral supplements. The water samples were filtered and analyzed for an available fraction of minerals viz., calcium (Ca), magnesium (Mg), potassium (K) and sodium (Na). The per cent release of each mineral from mineral mixture products was significantly (p≤0.05) increased with the increase in water salinity and the minerals availability varied with each product. This trend of mineral availability with an increase in salinity was not significant (p>0.05) with individual mineral salts. These findings can be useful for mineral supplementation calculations in shrimp culture ponds varying in water salinity.Pages: 430-434 | 591 Views 34 DownloadsDownload Full Article:
