One of the inserted pictures goes back to 1999 during the first training course hosted by the WorldFish Center (Abbassa – Egypt) for 14 Egyptian fish farmers while the second picture goes back to 2008 during an international training course held at the center. The purpose of night training was not just to measure the dissolved oxygen in given fish ponds but also to relate that to phytoplankton density in the ponds and compare the night readings to earlier and subsequent ones.
Regardless the cold weather as the pictures indicated, the participants in training courses usually appreciated such component in the training. Of course, we were keen to serve some hot drinks after such session. Whenever possible, I was keen to share this unique type of training with my colleagues and course participants.
