From yesterda's Parade Magazine Beware Which Fish You Eat Were decimating the worlds fish supply, warns Bruce Knecht, a sailor and author of Hooked: Pirates, Poaching, and the Perfect Fish. The populations of our most popular fish are less than 10% of what they were 50 years ago. The big reason is industrial fishingwhat Knecht calls the stripmining of fish, a lot of it illegal. Large species, from swordfish to Chilean sea bass (real name: Patagonian toothfish), are caught with lines that run for 12 miles and carry up to 15,000 hooks. In a single day, 30 tons can be caught, fired down a shoot, sawed up and thrown into a freezer. One boat can catch $3.5 million worth in three months. Much of our fish now comes from the Southern Hemisphere, and supplies there are running out too. In less than three years, virtually the entire population of toothfish in Chile, Argentina and the islands off Africa was wiped out, Knecht notes. Instead of allowing marine populations to rebound, the industry is racing to catch the last fish.
