Hydrology[edit] Water temperature is rather constant through the year, averaging 26–28 °С in summer and 25 °С in winter. Salinity is 34‰ (parts per thousand) in the center and northern part and up to 35.5‰ in the south. The coasts are sandy but the deeper parts are covered in silt. There are numerous coral reefs in the sea, such as the Lakshadweep islands which are made up of atolls and contain 105 coral species.[1][3][4] Fauna and human activities[edit]

fishing in the Gulf of Mannar, ca. 1926

The Gulf of Mannar
Gulf of Mannar
is known for its pearl banks of Pinctada radiata and Pinctada fucata for at least two thousand years. Pliny the Elder (23–79) praised the pearl fishery of the gulf as most productive in the world.[5][6] Although extraction of natural pearls is considered too expensive in most parts of the world, it is still conducted in the gulf.[7][8] Also collected in large numbers are Shankha
Shankha
mollusks (Xancus pyrum)[7] whose shells are used as a ritual and religious object. Other mollusks of the sea[9] are either too scarce or not popular in the Indian society and therefore have no commercial value.[10] Another traditional occupation in the Laccadive Sea
Sea
is fishing. The annual fish catch is 2,000 to 5,000 tonnes from the Lakshadweep islands, which is mostly constituted by tuna (about 70%) and shark. Perches, halfbeaks, Carangidae, needlefish and rays are also caught near the reefs. Shrimp, Achelata[1] and small fish, such as Sprattus, Pomacentridae
Pomacentridae
and Apogonidae
Apogonidae
are widely used as a bait by the Laccadive islanders.[11] With about 3,600 species of flora and fauna, the Gulf of Mannar
Gulf of Mannar
is regarded as one of the richest marine biological resources in the world. Of these 3,600 species, 44 are protected, 117 are corals, 79 crustaceans, 108 sponges, 260 mollusks, 441 fin fishes, 147 seaweeds and 17 mangroves.[12] In 1986, a group of 21 islands and nearby waters with the total area of 560 km² were declared Gulf of Mannar Marine National Park. The park and its buffer zone were designated as a Biosphere Reserve
Biosphere Reserve
in 1989. The Gulf of Mannar
Gulf of Mannar
Biosphere Reserve covers an area of 10,500 km² of ocean, islands and the adjoining coastline, and is the largest such reserve in India. Most of its area is restricted for outsiders and the access of boats is subject to strict rules,[13] but local people continue fishing activities which they crucially depend on. About 150,000 people live in the buffer zone, and more than 70% of them depend on the coastal marine resources. There are about 125 fishing villages with 35,000 active fishers and 25,000 divers for sea cucumbers in the area, about 5,000 women collect seaweed.[14][15] About 106,000 tonnes of fish were produced in the gulf in 2006, mostly oil sardines (Sardinella longiceps), lesser sardines ( Sardinella
Sardinella
spp.), ponyfish (Letognathus sp.), mackerel, penaeid shrimp, perches, squid (Sepioteuthis arctipinni), deep-sea lobster (Puerulus sewelli), crab (Varuna littorata), skates and rays.[10][16] The seaweed collection aims at shallow-water species Gelidiella acerosa (marikozhundu passi), Gracilaria edulis (Agarophytes, Kanchi passi), Sargassum
Sargassum
spp. (kattakorai), Turbinaria (Alginophyte, Pakoda passi) and Ulva lactuca, and is conducted between October and March. Because of National Park related restrictions, the production of seaweeds declined from 5,800 tonnes (dry weight) in 1978 to 3,250 tonnes in 2003.[17] References[edit]
