Down to Earth - - THE FORTNIGHT -

A green al­gae grow­ing in the Ara­bian Sea is threat­en­ing fish­eries in the re­gion. A re­port by Columbia Univer­sity's La­mont-Do­herty Earth Ob­ser­va­tory says green

Noc­tiluca scin­til­lans has been spread­ing over the last decade. It is a plank­ton that sur­vives in low-oxy­gen wa­ters and a grow­ing "dead zone" in the Ara­bian Sea has al­lowed it to dom­i­nate the re­gion. Dis­charge of nu­tri­en­trich sewage from coastal ci­ties is ex­pand­ing the dead zone. Fish­eries help sus­tain 120 mil­lion peo­ple liv­ing along the shores of Oman, In­dia and Pak­istan.
