This was one of the countless casualties of a mass death event that took place in the waters of the eastern Straits of Johor over the weekend. This die-off has been blamed on a plankton bloom. (Guest submission by @sgbeetlenut)

  •   nimblenewt Oh no! I love frogfish! Woe. 3d
  •   mondaymorgue We don't see frogfish very often here (probably because they're so well camouflaged!). It's sad that they were among the victims of this mass death event. 2d

mondaymorgue The mass die-off of fishes in the eastern Straits of Johor turned catastrophic on Saturday. Thanks @sgbeetlenut for sharing his photos on Facebook - much of the media attention has been on the offshore fish farms and their losses, but little has been said in the news about how the wild fishes have also been wiped out. It's through photos on Facebook and Ria Tan's posts on the Wild Shores of Singapore blog that we are getting a glimpse of the devastation of the populations of wild fishes.

I visited a short stretch of beach at Pasir Ris yesterday afternoon, and it was depressing - thousands of dead fishes were washed up on the shore, forming an unbroken line of carcasses, and the diversity of fishes affected was shocking. On one hand, this was a great opportunity to document fish species that I'd never personally encountered before, and add to my gallery, but the numbers were so overwhelming that I couldn't even think of taking photos of every carcass.

The scale of this year's mass death has been really alarming; a similar event took place in February 2014, but it seems like last year's was less severe compared to what's happened over the last 2 weeks. These episodes have been blamed on plankton blooms, which makes me wonder about the health and resilience of our marine ecosystems. It is worrying to think that this could become a regular occurrence.

  •   debitum_naturae I've actually been there. So sad to see how we're affecting the planet, especially the oceans. Many thanks for calling attention to the problem! 3d
  •   nimblenewt Super distressing. Have there been recent floods inland that might be washing large amounts of nitrogen into the ocean, feeding algal blooms and causing oxygen deficits? Or have the currents shifted in a way that might favour algae? I know this year's weather systems in southern westcoast Canada are making the oceans unseasonably warm at the moment, favouring unusual visits from Humboldt squid and other warmer water predators. Maybe you're getting affected (differently of course) by the same global weather patterns? 3d
  •   ikanbillie How does plankton bloom affect the fishes? /: 2d
  •   ylint Took a trip down to the beach ytd and today.. depressing indeed. :/ 2d
  •   mondaymorgue @ikanbillie: Too much plankton (usually microscopic algae) can deplete the dissolved oxygen content, causing marine animals to suffocate. This can happen at night, when the plankton stops photosynthesising and starts respiring, consuming all the available oxygen. Oxygen may also be depleted when there's a large amount of decomposing organic matter. In other cases, if the plankton is too thick, it actually clogs up or damages the gills of fishes and suffocates them. And in some species of algae, neurotoxins are produced, killing fishes and other marine animals that consume them. 2d

  •   nanang_laut What happen actually? Red tide? 4d
  •   mondaymorgue @nanang_laut: No official news on water quality at the moment. It might be a red tide - which means people need to be warned about consuming seafood caught/raised from these waters. 4d
  •   suenyee What about possibility of fish bombing? Most fish pictured were reef fish. 3d
  •   mondaymorgue @suenyee Nobody here uses such methods (most people who fish in these waters are small-scale recreational anglers), and there's way too many dead fish; it's been reported that a 'red tide' or some other form of harmful algal bloom is responsible for the die-off. 3d
  •   suenyee Fish bombing is illegal, so I wouldn't think it to be done in Singaporean waters. My father suspects fish bombing in the nearby islands on the South China Sea, the last time he witnessed such a mass death of fish with his own eyes was in Pulau Kapas in 1966; apparently fish bombing was employed (I thought he mentioned Thai fishermen, but I have to confirm with him), and the dead fish floated with the currents onto Pulau Kapas shores. What struck me as odd is the pictured fish e.g. moray, puffers are reef fish. Are there reefs in or nearby Pasir Ris? 3d
  •   suenyee Wouldn't algal bloom deplete oxygen levels? And some of the fish are bottom dwellers e.g. catfish? 3d

mondaymorgue I received information that something wasn't right with the water off Pasir Ris, so I went down to take a quick look yesterday. Unlike some previous mass mortality events, in which most of the fishes that died were those being raised in the offshore fish farms, many of the dead fishes encountered yesterday evening appear to be wild fishes, with a wide variety of species of all sizes being affected. This is quite worrying. 1w
