The Increase of Nephrocalcinosis (NC) in Rainbow Trout in Intensive Aquaculture
Spontaneous nephrocalcinosis (NC, urolithiassis) has been described in several species of salmonids in the wild (Herman, 1971; Landolt, 1975: Harrison, 1977) as well as in sea-farmed and freshwater-farmed rainbow trout (Mulcahy et al., 1980;Schlotfeldt, 1980). This can be confirmed from our own experiences. Different degrees of nephrocalcinosis were more or less regular additional findings in traditionally and extensively kept trout as well as being found sporadically in other salmonids from the wild, but in negligible percentages with no economic importance.
