Diving in Nosy Be, Madagascar
A preserved natureThe more
extraordinary side of Nosy Be island, is certainly coming
from the quality reefs. A Number : 410. the
amount of coral species a diver can observe in the area. Then,
more than this extraordinary diversity, corals are in prestine
condition. The big size of the reefs, the The small population
living in the area preserved
An exceptional bay:Apart from some exceptions during the rain season when tropical
storms are passing by and in september when weather can be
windy in the morning, the Ampasindava bay is always calm.
The Main land is sheltering the bay , the water is flat in

decreases to a minimum, so the sea is flat even in the afternoon
2 MAIN DIVING ZONES in Nosy Be

the south cape of Sakatia and Nosy Be. very sheltered from the main
winds (north and east) , and a little bit sheltered from the south
and west winds
Without currents most of the time, this zone is a very few under the influence
of the tidal currents
Shallow, the summit of the reefs is 6/9m deep, and the lower part, on the sand is 20/23m deep.
Very rich zone in "small things".As
the environnement of those reefs is very calm, all the little animals
which are usually hidden to be protected from the current can move
among the corals and are easy to observe. In this area, are easy
to see : paper fishes, ghostpipe fish, seahorse, rhinopias, pegasus, and plenty
Best place to see some green turtle, hawksbill, and some predators
like king fish, trevallies, barracudas. During october and the beginning
of november, it's possible to see humpack whales whith babies

NIGHT DIVE in Nosy Be
Night dives are organized just after sunset, in the protected
zone, very often on Olaf, otherwise on Anemone or Charlie..
it's useless to go deep, the most interresting is to observe
the sleeping species on the drop off which are active during
day time (coral fishes, parrots, sea horses.. ) and night
time active species (crustaceans, mollusks..), or species
coming near the reef during the night (squid, barracudas etc..)
FLUORESCENCE DIVE with BLUE LIGHT in Nosy Be
Same kind of dive as the normal night dive. The difference is we're giving you blue lights and filters to put on the mask. blue light is emitting in 450/470nm, which is "exiting" all colors of fluorescence (blue, yellow ,red..) instead of UV light, "exiting" only yellow and light green fluorescence.). the filter on the mask is to cut the blue light emitted, so you can see only the fluorescence emited by the animals / vegetals.
