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.</b> <br><br> The tunicates don&#39;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. <br><br> The tunicates don&#39;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. <br><br> <i>Source: CBC.CA</i>
