The objective of this study is to test the hypothesis that morphologically different mitochondria-rich (MR) cells may be responsible for the uptake of different ions in freshwater-adapted fish. Tilapia (Oreochromis mossambicus) were acclimated to high-Ca, mid-Ca, low-Ca, and low-NaCl artificial freshwater, respectively, for 2 wk. Cell densities of wavy-convex, shallow-basin, and deep-hole types of gill MR cells as well as whole-body Ca(2+), Na(+), and Cl(-) influxes were measured. Low-Ca fish developed more shallow-basin MR cells in the gills and a higher Ca(2+) influx than those acclimated to other media. However, fish acclimated to low-NaCl artificial freshwater predominantly developed wavy-convex cells, and this was accompanied by the highest Na(+) and Cl(-) influxes. Relative abundance of shallow-basin and wavy-convex MR cells appear to be associated with changes in Ca(2+) and Na(+)/Cl(-) influxes, suggesting that shallow-basin and wavy-convex MR cells are mainly responsible for the uptake of Ca(2+) and Na(+)/Cl(-), respectively.
