Scientists have developed the first-ever global map that shows the genetic diversity of freshwater and marine fish around the world...The researchers scoured through an open database of over 50,000 DNA sequences, representing 3,815 species of marine fish and 1,611 species of freshwater fish. They then estimated fish diversity in 200km2 sections of different water bodies. The greatest genetic diversity of marine fish was found in the western Pacific Ocean, the northern Indian Ocean and the Caribbean.
