IN THE WATER COLUMN—A PILOT STUDY Douglas-Helders, GM, O'Brien, DP, McCorkell, BE, Zilberg, D., Gross, A. Carson, J., Nowak, BF 3.2. 1 Abstract Amoebic gill disease (AGD) is the main disease affecting the salmonid industry in Tasmania, but no information on the distribution of the pathogen, Neoparamoeba pemaquidensis in the aquatic environment is available. This pilot study aimed to determine temporal and spatial distributions of paramoebae in the water column, using the immuno-dot blot technique. Water samples were collected from inside cages at various depths (0.5, 5.5, and 11.0 m) in both summer and winter, and at various distances (0, 0.5, 240, 280, 750, and 1100 m) away from the sea cages and farming site. Paramoebae densities were estimated using the most probable number technique (MPN) …
