Phy­to­plank­ton ac­tive in four gov­er­norates: MoAF

Muscat Daily - - NATION -

The Min­istry of Agri­cul­ture and Fish­eries (MoAF) has said that sea wa­ter turn­ing green in four gov­er­norates, namely North and South Bati­nah, Mus­cat and South Shar­qiyah, has been caused by phy­to­plank­ton.

De­rived from the Greek words phyto (plant) and plank­ton (made to wan­der or drift), phy­to­plank­tons are mi­cro­scopic or­gan­isms that live in wa­tery en­vi­ron­ments, both salty and fresh.

The min­istry said the phe­nom­e­non in­creases in the win­ter due to nat­u­ral fac­tors that stim­u­late its growth, such as change in wa­ter tem­per­a­tures and the move­ment of ma­rine cur­rents loaded with nu­tri­ents, as well as mon­soons.

The colour of the wa­ter changes to red, brown, orange, light yel­low or green, de­pend­ing on the colour of the phy­to­plank­ton.

The growth of phy­to­plank­ton in a large area leads to de­ple­tion or lack of oxy­gen dis­solved in wa­ter, and the death of fish and other ma­rine or­gan­isms col­lec­tively as a re­sult of suffocatio­n and in­abil­ity to breathe.

The min­istry has as­sured ci­ti­zens and res­i­dents that there are no en­vi­ron­men­tal dam­ages so far in the Omani wa­ter and the ex­ist­ing type of phy­to­plank­ton is non-toxic.
