People eat a lot of fish. In fact, per capita fish consumption has nearly doubled in the past 50 years. The problem is that there many not be anymore fish if we keep catching and consuming them at this rate. To calculate how many fish are left in the ocean, the Food and Agriculture Organization of the United Nations measures how many of each species were caught each year. Assuming that fishermen are catching as many fish as possible (they usually are), the logic goes that fluctuations in the number of fish caught gives a fairly good indication of fluctuations in fish population. Here is a look at how some of our most popular fish are doing.
