The brown mussel, is abundant on rocky shores along the coastal areas of the Arabian Sea of the Sultanate of Oman (Al-Barwani 2013). This species is considered endemic to Yemen, southern India, Sri Lanka, Madagascar, the southwestern Indian Oceans along the east coast of Africa, north of Luderiz Bay, the Mediterranean from Gibraltar to the Gulf of Tunis, the central and southwestern Atlantic Ocean along the coasts of Brazil, Uruguay, Venezuela, the West Indies, and recently colonized much of the Texan coast of the Gulf of Mexico (Hicks and Tunnell, 1995; Hicks ., 2001; Sokolowski 2010). The brown mussel in Oman has little economic value due to limited demands by the local people, and is only consumed by local coastal communities where it is prolific. However, recently the demand for imported mussels from Europe and New Zealand has increased due to the demand from the increasing expatriate communities in Oman. Nowadays, has gained some economic importance due the demand from hotels and seafood restaurants which cater to tourists and the expatriate communities.
The values of various population parameters obtained during the present study are given in Table 1.
