Effect of different concentrations of potassium and magnesium on performance of Litopenaeus vannamei postlarvae reared in low-salinity water and a biofloc system

The effects of magnesium concentration in low‐salinity water on growth of Pacific white shrimp ( Litopenaeus vannamei )

“…Insignificant differences in growth performances of shrimp in Zacarias et al. (2019) might be due to no Mg 2+ deficiencies in treatments (167–205 mg/L) compared to the level of Mg 2+ in diluted sea water (~156 mg/L) at the same salinity.…”

“…(2007) and Zacarias et al. (2019) reported no significant differences in final weights of Pacific white shrimp reared in low‐salinity (4 g/L) waters containing various levels of Mg 2+ , albeit a significant reduction in survival was observed in the lowest (10 mg/L) Mg 2+ treatment in the Roy et al. (2007) study.…”

Assessment of different ionic adjustment strategies in low‐salinity water on the growth of Litopenaeus vannamei and microbial community stoichiometry in a synbiotic nursery system

“…This is reflected in better growth results for shrimps in nurseries and grow‐out farming that used low‐salinity water with higher K⁺ supplementation, but with a high variability in survival rates (Antony et al, 2015; Roy et al, 2007). Despite the fact that maintaining Ca:Mg:K:Na ratios in low‐salinity water may be necessary in shrimp farming, the growth and survival results for nurseries using minimal water exchange in low‐salinity water, with different Ca:Mg:K ratios, had quite different results (Roy et al, 2009; Zacarias et al, 2019). Thus, it is important to determine appropriate minimum concentrations for marine shrimp growth and survival in shrimp farming in low‐salinity water using synbiotic system.…”

Effects of Dietary Salt-Based Minerals and Phosphorus Supplements on Mean Body Weight, Survival Rate and Feed Conversion Ratio of White Shrimp Reared In Brackish Water

“…Salt and phosphates are widely used in white shrimp culture in brackish water to improve performance (Faithong et al, 2006). Adding magnesium, calcium, potassium, sodium, chloride, sulfate, bicarbonates, and carbonates might be required to adjust the ionic water profile when rearing a white shrimp on brackish water (Zacarias et al, 2019).…”

“…The additional mineral is required when the salinity tends to decrease. Zacarias et al (2019) reported significant improvement in the survival rate of white shrimp reared in brackish waters by adding potassium and magnesium.…”
