During a dive along the Breakwater in Monterey, California in early June, Melanie Moreno, a Reef Check volunteer diver, observed what she suspected might be the invasive species, Sargassum horneri. Until the beginning of the decade most of the sargassum in the open sea was found floating in patches around the Gulf of Mexico and Sargasso Sea. The country currently imports $15m (£11.3m) of mutton and goat meat each year. In 2018, Laura Beristain Navarrete, mayor of coastal town Playa del Carmen in Mexico, told a local newspaper that tourist numbers in the region had fallen by up to 35% due to sargassum. Sargassum fish are found in marine habitats with a depth of 35.3 feet (11 m). Nylon fishing nets tangled in the coral reefs are also turned into fertiliser. T he Great Atlantic Sargassum Belt, first detected by Nasa observation satellites in 2011 and now known to be the world’s largest bloom of seaweed, … The rapid growth of this algae, along with its ability to repro-duce in a single season allows it to establish itself quickly, particularly in disturbed areas of sheltered bays that provide open substrate for offspring to settle and mature. The sargassum fish is found throughout the tropical and subtropical seas of the world. Sargassum is a troublesome addition to its new environs. It may look like the attached marine plants found in coastal waters, but it’s found in the middle of the North Atlantic Gyre. When it decays, it attracts insects that can cause skin irritation, while hydrogen sulphide exposure from rotting sargassum has been linked to neurological, digestive and respiratory symptoms. Sargassum is a planktonic (free-floating) seaweed found in the tropics. In the summer and fall, when sargassum is washed ashore along Atlantic beaches, many of these creatures will still be hiding within. After analysing 19 years of satellite data, researchers at the University of South Florida found that since 2011 the sargassum bloom has appeared annually and is growing in size. Sargassum muticum originally from Japan had by 15 March 1995 been found in Strangford Lough, County Down, Northern Ireland, this is an extension of the distribution of this invasive species. “Sargassum can suffocate coral reefs by covering them and decimate breeding grounds for turtles,” says Mike Allen, a marine scientist from the University of Exeter who has developed a cheap way of converting sargassum into biofuels and sustainable fertiliser. The area, of about 2 million square miles, is known as the Sargasso Sea. While the exact cause for the rise in sargassum is unknown, scientists suspect a combination of climate change and pollution from agricultural run-off is to blame. As sargassum decomposes on beaches, it releases disagreeable odours. And while many scientists have suggested that hot water could speed the growth of sargassum, “we found the opposite,” Hu says. The Sargasso Sea is a vast patch of ocean named for a genus of free-floating seaweed called Sargassum. Sargassum muticum is an invasive brown seaweed that has recently found its way to the shores of Ireland. Tehran says the US is in no position to set preconditions and economic sanctions must be lifted. It is recorded from Japan, China and Alaska. Why is it a problem?

In the Caribbean we find both S. natans and S. fluitans – two species which are holopelagic; they reproduce without ever being attached to the sea floor. The seaweed has inundated beaches, causing an environmental nuisance. Some species of Sargassum - a group of seaweed - live on the ocean's surface, where they attract fish, birds and turtles. Toilets: Men’s, Women’s or Gender-Neutral?

Sargassum polycystum on a rocky shore at Tanjung Rimau, Sentosa (Author’s own collection). Allen and a team of researchers from the universities of Exeter and Bath devised a process called hydrothermal liquefaction (HTL), which uses high pressure and temperature to split wet biomass into four components: a bio oil that can be upgraded to biodiesel, water-soluble organic compounds used to produce fertiliser, carbon dioxide (which the researchers say they aim to capture rather than release into the atmosphere) and char, a solid material containing all the metals found in the seaweed, which the team also plans to recover at a later stage. Before 2011, open-ocean Sargassum was mostly found in the Sargasso Sea, a patch of the North Atlantic enclosed by ocean currents that serves as a spawning ground for eels. searching for Sargassum 47 found (187 total) alternate case: sargassum.

However, too much of the seaweed can smother corals and seagrasses, and end up on beaches, releasing gas that smells like rotten eggs. The process is energy-intensive and runs on fossil fuels, says Allen, though heat from the process can be recovered and reused to improve efficiency. Two prevalent species in the Atlantic Sargassum natans and Sargassum fluitans, are found in … The Biomaya Initiative, an organisation established to deal with the sargassum glut, hires local residents to collect the foul-smelling seaweed from the beaches, and then cleans it to remove metals and plastics.

Sargassum horneri grows mainly subtidally, though intertidal populations have been reported in Laguna. It stalks its prey among the tangled weeds, relying on its cryptic camouflage for concealment. This is the only record for attached plants of a species of Sargassum in Britain.
