Kuriakose, P S and Surendranath, V G and Sivadasan, M P (1988) Possibilities of green mussel culture in the southwest coast of India. CMFRI Bulletin, 42 (2). pp. 247-256.
A simple and viable technology has been developed for the culture of green mussel Perna viridis on ropes suspended from floating rafts in the open sea at Calicut and Karwar along the west coast of India. Rafts varying in size from 5 x 5 m to 8 x 8 m were constructed using teak and bamboo poles and moored in the open sea at 8-10 m depth. Collection of seeds for the culture was done during October-December from the intertidal and submerged mussel beds. The average seed size for farming was 15-30mm and 0 5-1.0 kg seeds ere required for seeding one meter length of the rope. Synthetic and coir ropes of 15-20 mm diameter ware found suitable for growing mussels from the rafts. The seeds ware placed around the rope and securely wrapped with knitted cotton cloth. The seeded portion of the ropes varied from 5-8 m and the ropes were suspended from the rafts 0.5-1.0 m apart. Growth of mussels in the farm at Callcut ranged 11.6-12.9 mm in length and 5.9-7.3 g in weight per month. At Karwar the growth ranged 7.6-10.0 mm in length and 3 18-3.5 g in weight per month. A production rate of 12.3 kg per meter length of rope at Calicut and 10 kg per meter length at Karwar was obtained. Harvesting was dona at the end of five months. The possibilities and constraints of mussel farming in the open sea conditions are discussed in the Paper.
