We saw in Chapter 8 that over-fishing characterizes many fisheries around the world, and that in some cases fish stocks are as low as only 10 percent of their preindustrial fishing levels recorded in the 1950s. We also saw that with reduced fishing effort in a fishery more fish can be caught because fish stocks could recover. Properly designed fisheries management is a win-win-win-win game producing larger fish stocks, larger catches, less fishing effort and greater profits. The proviso, though, is “properly designed” because most of the many fisheries management systems that have been tried show little or no evidence of win-win-win-win.
