Crabs may be solution for tunicate threat

CANADA - Mussel growers are turning to the native rock crab for help in battling an infestation of Ciona intestinalis, a tunicate which is making it difficult to harvest mussels in eastern P.E.I. and slowing their growth.

The tunicates don't hurt the safety or quality of mussels, but they compete for food and completely cover the socks the mussels are grown on, making harvesting an expensive, labour-intensive process.
