Overview
- WWF-Pakistan says the bloom began in November and now appears in patches along the entire coast, with dense concentrations between Pasni and Jiwani.
- Gwadar’s western and eastern bays have visibly turned green, with similar discoloration reported from Karachi and extending toward Iranian waters.
- WWF-Pakistan and DWLF Pakistan report no associated fish mortality and are continuing shoreline and offshore monitoring to track its spread.
- Bottlenose dolphins were observed off Gwadar, and authorities say fishing activity remains normal with strong shrimp catches reported.
- Scientists explain the green hue comes from Noctiluca scintillans hosting the photosynthetic symbiont Protoeuglena noctilucae, with winter upwelling and eddies helping drive the bloom.
