Bonefish Spawn Offshore

Bonefish
Little is known about bonefish spawning, despite the fact it is one of the most populous sport fish in the Caribbean.  
A group of researchers tagged bonefish in Eleuthera, with ultrasonic transmitters to track their movement.  Tagging over 60 bonefish in two years, they have learned some insight into the life cycle of a bonefish.

One of the most interesting facts discovered is that for a few days, twice a month (new and full moon) from October to May schools of thousands of bonefish to spawn.  It was observed that at twilight the schools move out of the shallows to the edge of the drop and spawn.  Scientists believe the releasing of fertilized eggs out at sea increases the dispersal and the tides only exaggerate this. 

Now that scientists know that bonefish spawn at drop-offs, efforts can be made to establish conservational areas, and more accurately observe bonefish populations.  It is extremely interesting a fish that spends its entire life in the shallows, mates in the deep ocean.
