The numbers of chloride cells on the gills of three‐spined sticklebacks, Gasterosteus aculeatus , have been measured after exposure of the fish to 0.5, 1.0 and 1.5 mg Cd 2+ dm −3 soft water (132 mg dm −3 as CaCO 3 ) and 2, 4 and 6 mg Cd 2+ dm −3 hard water (299 mg dm −3 ). The numbers of chloride cells increased with time but later tended to decline. The significance of this finding is discussed in relation to the functions of chloride cells, one of which is presumed to be to eject absorbed heavy metals such as cadmium.
