Abstract
THE cause of blindness in some rainbow trout was recently described by me1 as being due to a trematode, Diplostomum volvens Nord., being present in large numbers in the lens of the eye. Since that date, two more lots of rainbow trout and one lot of roach have been examined, and in each case about five per cent of the fish were blind, due to a similar cause to that already recorded.
