Scientists use biodegradable straws to protect lab-grown coral from hungry fish
South Florida researchers are using biodegradable drinking straws to prevent laboratory-grown coral from becoming really expensive fish food.
FORT LAUDERDALE, Fla. (AP) — South Florida researchers trying to prevent predatory fish from devouring laboratory-grown coral are grasping at biodegradable straws in an effort to restore what some call the rainforest of the sea. Marine researcher Kyle Pisano said one problem is that predators like parrot fish attempt to bite and destroy the newly transplanted coral in areas like South Florida, leaving them with less than a 40% survival rate. Early prototypes of the cage made from phade’s standard drinking straws were able to protect the coral for about two months before dissolving in the ocean, but that wasn’t quite long enough to outlast the interest of parrot fish.
