 possible, but no supporting evidence is given.

Fishing News 



Strombus gigas briefly discussed as a potential species for 

 mariculture. Growth rates and potential predators of 

 conch mentioned. Pen rearing of conchs is recom- 

 mended, although low prices for whole conchs may 

 make mariculture impractical.
