In a former life, I had a lot to do with Greenshell mussels. There’s a large export industry based upon farming these shellfish, which are found only in New Zealand. Not only do they taste good, but they are also good for your health. (I managed to get off anti-inflammatory drugs for about seven years by including Greenshell mussels in my regular diet, but that’s another story.)
But this multimillion dollar industry recruits its juvenile mussels in a very strange way.
