Effects of Environmental Temperature on the Dynamics of Ichthyophoniasis in Juvenile Pacific Herring (Clupea pallasii)
Figure 1
Clupea pallasii. Cumulative mortality of diseased (ichthyophoniasis) and control Pacific herring in three temperature treatments. Data in (a), (b), and (c) are from fish undergoing simulated overwinter fast. Data in (d) are from fed treatments. Temperature adjustments were made 19 days after inoculation with Ichthyophonus schizonts. Data are means of 3 replicate tanks in each treatment. Error bars are one SD above and below the mean. Means and SD were calculated from arcsine-transformed data. Mortality data prior to day 19 are from the pools of infected and control fish prior to separation into treatment. Significant differences between infected and uninfected groups (Tukey multiple comparisons) indicated by * and ** for midpoint and end of challenge, respectively.
