    said Sharon Smith a plankton ecologist at the University of Miami who works in the Arabian Sea but was not involved in the study To understand the key to Noctiluca s success the researchers spent three successive winters aboard the Indian research ship Sagar Sampada starting in 2009 Sailing off the coast of Goa they sampled blooms and performed experiments Putting Noctiluca and itsdiatom competitors in oxygen starved water they found that Noctiluca s carbon fixation rate rose by up to 300 percent while the diatoms fell by nearly as much They also found Noctiluca grew faster in light than in dark thanks to its sun loving endosymbiont algae which are thought to have evolved 1 3 billion years ago on an oxygen scarce Earth The researchers tried to also identify Noctiluca s predators They had heard reports of Omani fishermen seeing more gelatinoussalps jellyfish and sea turtles Could they be eating the Noctiluca Scooping up several salps from the sea the researchers dropped them into buckets of seawater thick with Noctiluca blooms In an hour the water became visibly clearer By measuring the drop in chlorophyll the researchers estimated that one salp can polish off about two thirds of a bucket of Noctiluca in an hour They chowed on Noctiluca like rabbits in a lettuce patch said Gomes This is a creature that few other marine animals want to eat The Arabian Sea fishery may already be in decline In Goa India women sort through the morning catch Joaquim Goes Noctiluca is too big for the crustacean grazers that normally feed on diatoms leading to concerns that it could spawn an alternate food chain lacking the predator fish people like to eat Many fisheries in the Arabian Sea are already on a slow decline Eighty five percent of fishermen surveyed in the fishing dependent states of Tamil Nadu and Maharashtra in Indiareported a smaller catch from 20 years and 12 years earlier according to a 2014 study in the journal Oryx Similarly a rise in puffer fish off the coast of the Indian state of Kerala has been attributed to a crash in predator cobia fish since 2007 according to a 2013 study in Current Science In Oman the catch of large fish fell 18 percent in 2013 from the year before the Times of Oman reported Whether Noctiluca or overfishing is to blame one major factor stands out massive sewage flows into the Arabian Sea as the coastal population has exploded As the study authors point out Mumbai s population has doubled to 21 million in the last decade The region now sends 63 tons of nitrogen and 11 tons of phosphorus into the Arabian Sea each day Karachi s 15 million people send 70 percent of their wastewater into the sea untreated Much of the fertilizer used to boost yields on farms in South Asia also eventually washes into rivers that drain into the sea All of these cities are growing so rapidly they don t have
