What I did was anesthetize 15 fish and extracted 2 microliters of blood from each fish. Tomorrow I will do the same for 24 fish. It is suspected that the thyroid hormones play a role in the regulation of salt in the fishes blood. I am trying to find out what that role is. Mixing the different required chemical mixtures, the blood extractions and the injections pretty much took all day.
Tomorrow is more of the same.
The is the drudge part of research but it has to be done. I will get more chances to head outdoors on Tuesday or Wednesday so stay tuned. Bye for now.
