... the deuterium oxide dilution technique. Rates were quantified in animals using four experimental treatments: (1) held in fresh water and fed lettuce ( N =4), (2) held in salt water and fed lettuce ( N =2), (3) acutely exposed to salt water and fed lettuce ( N =4), and (4) chronically exposed to salt water...

..., there was a net influx of Na + and Cl − . While our data showed that Ca 2+ influx rate was reduced by colchicine treatment in freshwater-adapted tilapia, it is well known that fish gills actively excrete NaCl in salt water and take up NaCl in fresh water. Therefore, these results suggest that disruption...

... MR cells that are in contact with the water (cells labelled with both DASPMI and Concanavalin-A) and those that are not (DASPMI-positive only). This method was used to describe differences in MR cell density that occur in the gills of tilapia Oreochromis mossambicus adapted to fresh water or sea...

...William S. Marshall; Sharon E. Bryson; Chris M. Wood ABSTRACT The skin overlying the cleithrum bone of freshwater-acclimated rainbow trout contains numerous mitochondria-rich (MR) cells, as detected by DASPEI fluorescence. This tissue was mounted in vitro in an Ussing-style chamber with fresh water...

... pH compensation was facilitated when animals were exposed either to bicarbonate-enriched fresh water ( Perry et al . 1981 ) or to progressive increases in external salinity at constant [HCO 3 - ] (G. K. Iwama & N. Heisler, personal communication). In the present study, our sea water contained...
