We had 2 days of lectures that focused on fieldwork/survey techniques and sample collection, and I included some interactive activities such as practicing standard measurements (no real manatees or even an inflatable toy manatee available, so we used my inflatable orca again). Even though it's not the real thing, I find that just having the opportunity to do measurements on a 3D scale gives the guys a much better understanding of how to accurately take the measurements in the correct standardized way. We talked about the realities of doing a necropsy (because manatees are heavy and hard to manouevre if you've never done it before!). We also went over equipment and how to use and care for it.
Dawda shows Lamin how to use the refractometer (which measures water salinity) while Musa and Fabala look over their datasheets.
