Status and Distribution of Trochus niloticus (Linnaeus.
Trochus niloticus are gastropods belonging to the family Trochidae. They are marine animals that inhabit intertidal and shallow subtidal areas of coral reefs, mainly in exposed aspects. In Australia, trochus are collected from remote reefs in Western Australia and Queensland either from reef tops at low tide or from the subtidal areas adjacent to the reefs. In Australia trochus can attain 16.
Trochus is a genus of medium-sized to very large sea snails.They are marine gastropod molluscs in the family Trochidae, the top snails. Trochus niloticus, for example, is a very large (up to 13 cm) Indo-Pacific top shell, which has a very thick inner layer of nacre.This species is commercially exploited to make mother of pearl buttons, mother of pearl beads, pendants and so on.
Africa: naturally occurring in coastal rivers of Israel (Ref. 5166), Nile basin (including lake Albert, Edward and Tana), Jebel Marra, Lake Kivu, Lake Tanganyika, Awash River, various Ethiopian lakes, Omo River system, Lake Turkana, Suguta River and Lake Baringo (Ref. 2).In West Africa natural distribution covers the basins of the Senegal, Gambia, Volta, Niger, Benue and Chad, with introduced.
Intentional release of wild-caught individuals has been widely used to establish new populations of the commercially valuable but threatened reef gastropod Trochus niloticus in oceanic islands. Is this also a viable strategy to enhance depleted populations of this species and other marine invertebrates? We monitored growth and survival of 765 translocated individuals and 486 in their original.
Trochus niloticus - Tectus niloticus is a genus of medium-sized to large, top-shaped sea snails with an operculum and a pearly inside to their shells. Sea snails in the genus trochus have shells that have a broadly conical spire and a flat base. The interior of the shell is pearly and iridescent because of a layer of nacre (mother of pearl). This specie is commercially exploited to make mother.
