“…In this study, the fish-fed control diet and diet containing 5.3 g/ kg Ca exhibited the poor growth performance and mineralization, demonstrating that these diets had suboptimal Ca level than the required level. Similar results of Ca deficiency were also reported in Cirrhinus mrigala (Paul et al, 2004), Ctenopharyngodon idella and Labeo rohita (Musharraf & Khan, 2020).…”

“…The enhancement in whole-body protein might be attributed to better protein metabolism resulting in better growth performance, mineralization and protein retention in fish at this level (8.3 g/kg) while the increased ash content at higher Ca levels corresponds to the high concentration of essential elements such as Ca and P in diet (Zafar & Khan, 2019). Similar to our result, Musharraf and Khan (2020) and Zafar and Khan (2019) noted significant improvement in wholebody protein and ash contents of juveniles at higher Ca levels.…”

“…In the present study, Ca concentration in whole body, bones and scales improved with increasing Ca levels, indicating that Ca is essential for mineralization in fish. Similarly, Musharraf and Khan (2020) reported that an increase in Ca supplementation up to 5.11 g/kg significantly enhanced Ca concentration in Labeo rohita juveniles. Zafar and Khan (2019) noted a maximum increase in Ca concentration in whole body, vertebrae and bones at 6.71 g/kg Ca level.…”

“…Labeo rohita (Musharraf & Khan, 2020) and lower than that of Hypophthalmichthys nobilis (Liang et al, 2018). The variations in Ca requirements may owe to the difference in fish species, size of fish, experimental conditions, diet composition and Ca concentration in water.…”

“…However, Zafar and Khan (2019) reasoned that Ca involved in the precipitation of fats that decreases its absorption in the intestine resulting in enhanced fats excretion through faeces (Zafar & Khan, 2019). Conversely, no significant changes were reported in the whole-body lipid content of Hypophthalmichthys nobilis (Liang et al, 2018) and Labeo rohita (Musharraf & Khan, 2020). This difference in lipid content of various fish species as a result of dietary Ca supplementation may be due to discrepancies in fish size, trial duration, experimental environmental conditions and diet composition.…”

Calcium (Ca) is one of the essential minerals in both terrestrial and aquatic animals (NRC, 2011). It plays key roles in osmoregulation, blood clotting, acid-base equilibrium, bone mineralization, nerve transmission, contraction of muscles, the integrity of cell membrane, skeletal development and enzyme activation (NRC, 2011). Bones and scales are considered the major sites for Ca deposition in fish . In teleost, about 99% Ca is incorporated into their scales and bones (Hossain & Yoshimatsu, 2014). Deficiency of Ca resulted in stunted growth, skeletal deformities and low mineralization in fish (Liu et al., 2021).Generally, it is accepted that most of the fish have the ability to meet their Ca requirement by drinking surrounding water (Lall, 2002).Different structures of fish such as oral epithelia, gills and fins are involved in absorption; however, gills are regarded as the most effective organs for Ca absorption (Flik & Perry, 1989). Freshwater fish have more ability to uptake Ca from surrounding water than marine fish as they have higher serum Ca level than freshwater (Hossain & Yoshimatsu, 2014). They can meet their Ca requirement either
