ivalve Molluscs such as oysters, mussels, scallops, clams and cockles comprise a significant part of the world’s fisheries production.
According to the statistics of the Food and Agriculture Organization (FAO), over 14 million metric tons of bivalves are produced
annually through aquaculture. China, Japan, South Korea, Vietnam and Thailand are the pioneers in the market. During the decade
from 2000 to 2010, a rapid increase was seen in the production of bivalves and landing doubled from 7 million MT in 2000 to more
than 14 million MT in 2010. During this period bivalves landing from the wild increased slightly from 2.5-3.5 million MT while
cultured bivalves doubled during the same period increasing from 6.3 -14 million MT comprising nearly 75% of the world bivalve
production. Sri Lanka is a South Asian Tropical Island in the Indian Ocean. It has total land area of 65610 km
2
with a population of
22 million, coastal line of the island about 1340 Km with 158,000 ha of brackish water areas (lagoon and estuaries). The country is
very rich in economically important bivalves such as oysters (
Crassostrea madrasensis, Saccostrea cucullata
) mussels (
Perna viridis,
P perna
), clams (
Marcia opima, M. hiantina, Meretrix casta
) cockles (
Gafrarium tumidum, Anadara granosa
) and pearl oysters
(
Pinctada vulgaris, P. margaritifera
) around the coastal areas. Fishermen harvest bivalves from natural habitats in Negombo, Chilaw,
Kalpitiya, Mannar, Jaffna, Trincomalee and Southern coastal belt of the country. Though bivalve farming is not commonly practiced
in the country, a very high potential is available in the above specified areas. However, with the booming of the tourism industry in
coastal areas of Sri Lanka, an attractive marketing atmosphere in other countries, the community based bivalve farming has started
in many parts of the country through government initiation. Bottom, rack, stake and raft culture systems are used for the farming of
oysters, mussels and clams in these areas. Naturally available untapped bivalves, unpolluted marine water, cheaply available culture
materials, low cost labour availability of technology and government support are also encouraging factors for investment in bivalve
farming in Sri Lanka.

University of Liverpool, United Kingdom. He contributed immensely in developing the prawn farming industry and hatchery sector in Sri Lanka. He has been
recognized for introducing oysters, mussels, clams and cockles farming in Sri Lanka and is also a pioneer in introducing pearl culture in freshwater reservoirs. He is
a Founder Member of the Asian Fisheries Forum (AFS) and Sri Lanka Association for Fisheries and Aquatic Resources (SLAFAR). He has wide experience and a
profound understanding of aquaculture and aquatic environment in many European and Asian countries. Currently, he serves in advisory capacity to few ministries
