“…The possibility of these conflicting results in different freshwater species may be that the magnesium requirement changes depending on species, and waterborne Mg concentrations could significantly affect the magnesium requirement of fish (Shearer & Åsgård 1992). Common carp and freshwater tilapia have been found that they can absorb Mg from water when they fed low Mg diets (Van der Velden et al. 1991a,b).…”

Gibel carp (Carassius auratus gibelio) of mean initial weight 3.1 g were fed one of seven casein‐dextrin‐based diets containing graded levels of magnesium (Mg) (39, 120, 220, 380, 700, 1600 and 2900 mg kg−1) for 3 months with the waterborne Mg concentration of 10.6–12.7 mg L−1. Magnesium sulphate was used as the supplementation Mg source in the diets. The experiment was carried out in a flow‐through system. Growth, survival rate, Na+/K+‐ATPase, Mg2+‐ATPase and tissue mineral contents were measured to investigate the effect of dietary magnesium in gibel carp. At the end of the experiment, the hepatopancreas of fish were collected for enzyme determination. The hepatopancreas, vertebrae and whole body were collected for tissue magnesium content analysis. After 3 months, dietary magnesium supplementation did not improve the growth performance, including feed intake, weight gain and feed conversion efficiency of juvenile gibel carp. On the contrary, negative impacts on survival, reduced growth performance and dramatically decreased Na+/K+‐ATPase, Mg2+‐ATPase and superoxide dismutase activities were observed in gibel carp fed a high Mg diet of 2900 mg kg−1. Although serum and hepatopancreas Mg and Ca contents were not affected by dietary Mg supplementation, vertebrae and whole‐body Mg contents increased significantly with the increasing dietary Mg concentrations. Based on the relationship between whole‐body Mg retention and dietary Mg concentration, a suitable dietary Mg level of 745 mg kg−1 could be estimated for gibel carp. It could be concluded that dietary Mg supplementation did not improve the growth performance, but could increase vertebrae Mg contents of gibel carp. Considering the adverse effects, a dietary Mg concentration of above 2900 mg kg−1 is not recommended and it should be careful to supplement magnesium in practical diets for gibel carp as most feed ingredients contain high magnesium concentrations.

Physiological effects of low‐magnesium feeding in the common carp, Cyprinus carpio

et al. 1992

View full text Add to dashboard Cite

Common carp (Cyprinus carpio) initially weighing about 100 g were fed a lowmagnesium diet for 17 weeks. The fish survived this treatment and had a healthy appearance. However, the fish became hypomagnesemic and their growth rate decreased. The bone sodium concentration increased and the magnesium concentration decreased. It thus appears that in carp, under dietary magnesium deficiency, magnesium is mobilized from internal stores and that magnesium in the bone mineral is replaced by sodium. Low-magnesium fed carp farther showed a decreased branchial Na*/ K * -ATPase specific as well as total activity. Unexpectedly, the opercular chloride cell density in creased. We tentatively conclude that more and new chloride cells with a lower Na + /K +-ATPase content develop during this treatment. We further conclude that adult carp require dietary magnesium for the maintenance of their magnesium balance as well as for the proper functioning of branchial ionoregulatory mechanisms. Low-magnesium fed carp do not acclimate but appear to tolerate a dietary magnesium deficiency, f
