We examined whether ionoregulatory mechanisms of fresh water Fundulus heteroclitus in vivo are similar to those of typical freshwater species (e.g., rainbow trout, goldfish, and catfish). Under control conditions ([NaCl] ext ~1 mmol/l), the mummichog exhibits very large Na + influx and efflux rates
We adapted killifish to defined freshwater (FW: 1.0 mM Na + , 1.0 mM Cl -, + 0.1 mM Ca 2+ ) and by fluorescence light microscopy and scanning and transmission electron microscopy found that the opercular epithelium retained mitochondria rich (MR) cells that were significantly larger but less numerou
