[Coral-List] Responding to Coral Bleaching

Here in Fiji we tried scattering COTS in a cassava field for fertilizer but
the village chickens (and hungry dogs) ate them all up, so the experiment
failed.  But we learned another potential use!  I have tried eating the
eggs, and they are delicious at first, followed by a very bitter taste-
nope!
