How to eat seafood that's healthy for you and sustainable for the oceans

Seafood offers a lot of health benefits, like lean protein and healthy fats, but our taste for it isn't so beneficial for the earth. Many popular fish stocks are increasingly threatened; just this week, the International Union for Conservation of Nature warned that more than 40 species of fish — including bluefin tuna and sea bass — are in danger of becoming regionally extinct due to overfishing in the Mediterranean.

A new cookbook from Ocean Wise, a conservation program created by the Vancouver Aquarium, offers tips and recipes for including seafood in your diet in a responsible way. The Ocean Wise Cookbook starts with a great section of tips, including advice on how to shop for seafood and suggestions for seafood substitutions when you can't get what the recipe calls for. It's also full of delicious-looking recipes using seafood from sustainable stocks, including mahi mahi, scallops and sardines.

The recipes in this cookbook come from Canada's chef A-list, and cover the country coast to coast. The contributors include Rob Feenie, Canada's first Iron Chef; Jamie Kennedy of Jamie Kennedy Kitchens; and Michael Smith of Chef at Home.
