Also known as bomb fishing or dynamite fishing, blast fishing is a critical issue in Tanzania, says Kennedy Osuka, a fish ecologist at the University of Liverpool in England. Osuka has spent seven years studying the Tanzanian coral reefs that have been reduced to rubble by blast fishing. For those concerned about the country’s marine habitats, artisanal fisheries, or tourism industry, “stopping blast fishing is of the utmost importance,” Osuka says.
