Rain brings studying and sun means snorkel........

Lisanne, Sheril and Marie practicing coral ID |
Last week we stayed in the office a lot
due to the bad weather caused by a big cyclone around Madagascar. Ideal weather
to stay inside and study the most common fishes and corals, as well as
developing a reef impact and substrate data collection sheet. This to assess
the bleaching rate and the diversity of corals on the reef of Fishermen’s Cove.
The monitoring is going to start in two weeks and that is to give us time to
learn more about the corals for when we start the transects. In the process we
have started to do coral ID to better identify them once we start the
monitoring.

On Friday the sun came back again, so we
decided to test our coral and fish knowledge in the field during a snorkeling
trip at Sunset Beach. Butterflyfish, Batfish, Moorish Idol and brain coral, we
recognized a lot already! The water was surprisingly warm and the corals looked
beautiful. But more and more white corals appeared as we swam further.

This is
due to a huge bleaching event that is going on the past couple of weeks. Corals
suffer from the warm temperatures and lose their symbiotic zooxanthellae
which give them their nice colours. The white coral carpets underneath us were
not a pleasant appearance. Hopefully the water temperature will drop soon, so
the corals get time to recover. Looking forward to practice the enhanced skills in the water. We hope that we have sunny days ahead to start identifying the transect area where we can do our reef check.
