Some Fish Stocks Have Collapsed from Overfishing
Notes:
Commercial Harvests in the Northwest Atlantic of Some Important Fish Stocks, 1950-95
According to an FAO analysis, based on fish harvest records from 1950 to 1994, 35 percent of the most important commercial fish stocks show a pattern of declining yields and require immediate action to halt overharvesting. Another 25 percent show steady yields but are being fished at their biological limit and are vulnerable to declines if fishing levels increase.
