Large-scale exploitation of sacred chank Xancus pyrum using modified trawl net along Rameswaram Coast, Tamil Nadu

The sacred chank, Xancus pynim is a gregarious, large gastropod and its habitat forms distinct chank bed. Homell as early as 1922 described the chank beds in depths of 10 to 20 metres in the Gulf of Mannar and are considered as the most important ones in the country although there are other chank beds along the Gulf of Kutch and the southwest coast of India

Ornamental shell industry of Ramanathapuram coast

As many as twelve shell craft Industries established at KeelaVaral and Ramaswaram cater to the demand of the internal and external market of ornamental shells in India and abroad. Several species of molluscan shells which occur in the Gulf of Mannar and Palk Bay constitute the raw materials for these industries. Apart from very rare SPECISS, 15 important species are regularly exploited for this purpose. The Genus /.a/n^/s commonly known as 'Spider conch' is very Important among them by virtue of its abundance. Of the 9 species of Lambis known from India, only 3 species art abundant in this coast Exploitation of these shells are mostly by skin diving and to a limited extent by trawl, gill and drag nets employed mainly to catch finfishes, lobsters and crabs. This paper mainly deals on the ornamental, curious and religious values of molluscan shells, their Industry, types of shells and species used by the industry, varied products, marketing, employment opportunities and certain aspects of costs and earning of the industry

Instances of finless black porpoise, Neophocaena phocaenoides caught in Mandapam region along the Palk Bay coast in Tamil Nadu

The flnless black porpoise, Neophocaena phocaenoides G. Cuvier is widely distributed in the Indo-Pacific ranging from Cape of Good Hope to Japan and China and often known to ascend the estuaries of larger rivers. In India, this species is fairly common along the coasts of Bombay, Madras and Trivandrum. Since, porpoises are considered as endangered marine mammals, strict regulations have been imposed by the Government authorities for their conservation and management. Incidental catch of porpoises reported in the west coast is more than in the east coast of India as may be seen from the published information. It appears that propoise, Neophocaena phocaenoides frequents the coastal waters and gets captured on many occasions. More recently, incidental catch of porpoises are on the increase in Mandapam region

Observation on the culture of green mussel in Pillaimadam salt water lagoon, near Mandapam

The Pillalmadam salt water lagoon (09°17'N and 79°06'E), located near Mandapam, in Ramnad district is bound by the Palk Bay on the north and the Rameswaram-Ramnad rail road on the south (Fig.l). It extends to a length of about 5^g km, covering an area of about 450 ha. The lagoon is connected to the Palk Bay by a bar mouth, through which it receives the tidal water. During the north-east monsoon (November and December) the lagoon gets rain water mainly through the Pillaimadam creek. Although the suitablity of the lagoon for finfish culture
