The roles of water temperature, flow and agitation on the development and settlement of sea lice on their Atlantic salmon hosts were investigated in the laboratory. In the first phase, fish were exposed to 5, 10 or 15 degrees C and increased water-flow (18 vs. 6 litre/min). In the second phase, fish...

The host parasite system of the MSX parasite, Haplosporidium nelsoni, in the eastern oyster, Crassostrea virginica, poses many challenges for experimental study. The interactions that are involved in the development of the typically high prevalence and intensities of disease encountered in certain e...
