We are so lucky here on the West Coast to have such a variety of amazing shellfish. Many of the commercial species we have here were introduced from other parts of the world. But I think that they have little impact on the native shellfish population and have indeed found a nitch here.

The ocean waters flowing down the coast from northern climates are rich with nutrients and very cold. This makes the prime areas for shellfish production around the central area of Vancouver Island. The cold waters we have here are necessary for fine flavors of our shellfish. The nutrients that are in this water provide plenty of food for rapid growth.

There are many fresh water shell fish on Vancouver Island, although most are not edible, they are still very fascinating to study. There is something quite awesome about seeing the variety and abundance of shellfish on Vancouver Island.
