sargassum species list

[3], The Florida Keys and mainland South Florida are well known for their high levels of Sargassum covering their shores.

It matures early in its life, has both male and female components on a … However, characteristics vary and identification of a particular sample may not be straightforward. [24] Since 2011 increasingly stronger inundation events have occurred every 2-3 years. Most species within the class Phaeophyceae are predominantly cold-water organisms that benefit from nutrients upwelling, but the genus Sargassum appears to be an exception. The two predominant species of sargassum in the Sargasso Sea are the only seaweeds in the world that don’t begin life attached to the seafloor. The seaweed (Sargassum) is a type of open ocean brown algae. Commercially important dolphin fish, amberjacks, and tuna are some of the large predators that also use this habitat. It is free-floating seaweed and will not attach to the ocean floor; its movements depend solely on ocean currents. During a sargassum inundation event in 2018, one sargassum bloom measured over 1600 square kilometers, more than three times the average size.[24][25]. [8] These endemic organisms have specialized patterns and colorations that mimic the Sargassum and allow them to be impressively camouflaged in their environment. The scientific name comes from the Latin histrio meaning a stage player or actor, and refers to the fish's feeding behaviour. These endemic … Fishery management plans developed by the Council include: Coastal Migratory Pelagics (includes king & Spanish mackerel), Coral, Dolphin Wahoo, Ecosystem-Based Amendments, Golden Crab, Habitat, Sargassum, Shrimp (including rock shrimp), Snapper Grouper, and … Recent inundation events have caused millions of dollars of lost revenue in the tourism industry, especially hurting small Caribbean countries whose economies are highly dependent on seasonal tourism. There are two species commonly found in the Caribbean, s. natans and s. fluitans. [50] As anthropogenic forces increase the variability of these factors the frequency, duration, severity, and geographic range of harmful algae blooms has increased causing millions of dollars of lost revenue as well as damaging fragile coastal and coral ecosystems. Familia: Sargassaceae. The Sargasso Sea plays a major role in the migration of catadromous eel species such as the European eel, the American eel, and the American conger eel. Marine mammals (dolphins) and juvenile loggerhead sea turtles have also been observed among the Sargassum. The sargassum fish, anglerfish, or frog fish (Histrio histrio) is a frogfish of the family Antennariidae, the only species in its genus.It lives among Sargassum seaweed which floats in subtropical oceans.

[36] Historically, low nutrient levels in the Sargasso Sea have limited sargassum production; however, new influxes of nitrogen and phosphorus are driving factors in increased biomass production[37][38][39], Recent studies have found three likely drivers of nutrient influx linked to increasing sargassum biomass: an increase in nutrient output from the Amazon River, increased nutrients in the Gulf of Mexico, and coastal upwelling off the West African Coast which transfers deep nutrient-rich waters to the upper water column where sargassum resides. (2013, June 01). Sargassum has different species which produces a different variety of products. Numerous species are distributed throughout the temperate and tropical oceans of the world, where they generally inhabit shallow water and coral reefs, and the genus is widely known for its planktonic (free-floating) species. [40], The physical drivers behind sargassum inundation events are prevailing winds and ocean surface currents.
