Coral spawning in PR.

[Ernesto Weil]

Dear colleagues, spawning of Montastraea spp. occurred right on time this year in Puerto Rico. Here are my observations:

September 1st (6 days after the full moon):

7:55 - 8:40 p.m. M. franksi and M. cavernosa

10:30 - 11:10 p.m. M. annularis and M. faveolata 

M.annularis started to spawn before M.faveolata, then they overlapped for about ½ hour, M.annularis stopped and M.faveolata continued to spawn afterward for a short period of time. 

September 2nd. (7 days after the fool moon) : bad weather so, observations were made in specimens collected on August 30th and keept in aquaria with running seawater. 

8:45 - 9:20 p.m M. franksi

10:30 - 11:10 p.m. M.annularis 

11:00 - 11:50 p.m. M.faveolata

Saludos,

EW.
