It warned that the world's ocean fish could be almost gone by the middle of the century. Now, a new study offers more hope. It shows that the risk of fisheries 28 has recently decreased in some areas – some, but not all. "This means different regions are 29 in different directions and some regions have indeed begun to get rid of overfishing." Boris Worm at Dalhousie University in Canada and Ray Hilborn at the University of Washington in Seattle were lead authors of the new study.

Only two areas did not have an overfishing problem in either the new study or the 33 one. The new study found that overfishing has been reduced in Canada's Newfoundland-Labrador area and in Iceland and southern Australia.Using nets that let smaller fish escape and agreeing not to fish in certain areas can help reduce overfishing. The study showed that these measures helped fish populations 34 in Kenya. But one of the authors of the study, Tim McClanahan from the Wildlife Conservation Society, says fisheries in Africa face another 35 . Most countries in Africa are selling fishing rights to industrialized nations which catch large amounts of seafood. The study shows what happened when industrialized nations increased 36 on fishing in their own waters.
