Are Herring Energetics a Limiting Factor Quarterly Tasks

2009 Quarterly Project Tasks:

1st Quarter Tasks (October 1, 2008 - December 31, 2008)
Status: Complete

Tasks to be performed:

October Infect herring for Objective 2a November Partition infected herring into appropriate tanks, adjust temperature, and initiate starvation experiment, collect field samples December Continue sampling for Objective 2a, collect field samples

Progress report:

All Completed

2nd Quarter Tasks (January 1, 2009 - March 31, 2009)
Status: Complete

Tasks to be performed:

January Complete sampling for objective 2a and break down the experiment Infect herring for objective 2b Annual Marine Science Symposium February Partition infected herring into appropriate tanks, adjust temperature, and initiate starvation experiment (Objective 2b). March Continue sampling herring for objective 2b, collect field samples

Progress report:

Attended AMSS In general, all aspects of the project are on schedule with the exception of a slight delay in the laboratory component. During the first food deprivation study, the kinetics of ichthyophoniasis mortality superseded those of starvation mortality, so it was decided to perform a second trial and adjust the experimental design by starting with herring that were infected, but not yet diseased with Ichthyophonus. We are currently 80d into the experiment and plan to terminate the experiment in the coming weeks. Subsequent lab trials (Objectives 2b and 2c) will continue through the summer and should be finished by the end of September.
