“…Saoud and Davis (2005) reported that betaine supplementation at low (0.5 g L −1 salinity) or high (50.0 g L −1 ) salinity did not influence shrimp growth. Likewise, Saoud et al. (2007) reported no significant effects on growth or survival of L. vannamei fed diets supplemented with arginine when reared in low salinity waters (1.3 g L −1 ).…”

“…However, multiple studies conducted on site at low salinity shrimp farms in west Alabama failed to support the laboratory results obtained using chelated minerals. Furthermore, in a tank study utilizing a flow‐through system supplied with low salinity water (1.3 g L −1 ) from a shrimp production pond, chelated potassium did not improve the growth or survival of L. vannamei in low salinity waters of west Alabama (Saoud et al. 2007).…”

“…Thus, presently it is recommended that diets should be supplemented with magnesium to meet the requirement of most freshwater species (0.15% diet) and the use of a chelated K (1% diet) may be helpful, although results have been inconsistent (Roy et al. 2007b; Saoud et al. 2007).…”

“…Dietary supplementation of FAA, such as betaine and arginine, has been suggested as a potential means to improve the osmoregulatory capacity of L. vannamei reared in low salinity environments (Saoud & Davis 2005; Saoud et al. 2007).…”

Inland aquaculture of shrimp in low salinity waters is widespread in many regions worldwide. Owing to its ability to grow and survive in low salinity environments the Pacific white shrimp, (Litopenaeus vannamei Boone) has become the candidate of choice for low salinity culture. Remediation techniques have been developed to improve the osmoregulatory capacity of shrimp reared in low salinity waters. These techniques have evaluated water modification strategies that improve low salinity waters used for production by adding potassium and magnesium fertilizers and dietary approaches that involve modification of the feeds offered to shrimp with supplements that might improve osmoregulatory capacity. Based on our own experience as well as what we found predominantly in the literature, it appears that modification of the rearing medium with potassium and magnesium fertilizers is more effective than dietary modification techniques at improving the growth, survival and osmoregulatory capacity of shrimp reared in low salinity waters.

“…They reported that chloride salts (potassium chloride, magnesium chloride, and sodium chloride) did not prove effective in improving shrimp growth. Another study examining the supplementation of chelated K to diets of shrimp reared in low‐salinity water originating from production ponds at two west Alabama farms demonstrated no significant differences in growth, survival, weight gain, or osmoregulatory capacity of L. vannamei (Saoud et al 2007).…”

Shrimp farmers using inland low‐salinity waters in west Alabama have traditionally used agricultural fertilizers (K‐Mag®, muriate of potash) to raise pond water levels of potassium (K) and magnesium (Mg) to improve the rearing medium for Litopenaeus vannamei. Laboratory and farm trials were performed to investigate the potential of using dietary supplementation of Mg instead of costly agricultural fertilizers. A 5‐wk laboratory trial was devised to test four diets with varying levels of Mg supplementation (0, 0.15, 0.30, and 0.60% Mg chelate) using a magnesium chelate (MgC)–amino acid complex. Juvenile shrimp were stocked into artificial low‐salinity water (5 ppt) designed to contain low levels of Mg. A farm trial was also conducted to test the same diets under field conditions. Although both laboratory and on‐farm trials revealed a trend for increased growth using the diet with the highest Mg supplement, results were not significantly different. The use of magnesium chelates as dietary supplements at levels higher than the requirement level to enhance survival, growth, and osmoregulatory capacity of shrimp reared in inland low‐salinity well waters appeared to have limited potential. Until effective specialized diet formulations are produced, farmers should continue to supplement pond waters with fertilizers containing K and Mg.
