Abstract

The mussels are bivalve molluscs found attached to the hard surfaces in the littoral and sublittoral zones. They attach themselves to the substrate by secreting long threads called byssus. Though they are considered sedentary, they may move from one area to another if faced with unfavourable environmental conditions. Mussels are regarded as one of the best candidates for aquaculture since they are filter feeders feeding at the lowest level in the food chain (primary consumers); they feed on phytoplankton, detritus and associated microscopic flora and fauna. The two important species of mussels in India are the Green mussel Perna viridis(Peacock mussel/MayilpeeliKakka/Kallummekaya) and the Brown mussel Perna indica (Red chippi). The green mussel has a wider distribution along the west and east coasts of India, including the Andaman Islands. In contrast, the brown mussel is restricted to the southwest coast of India. Along the east coast, the green mussel is found in Chilka Lake, Kakinada, Madras, Pondicherry, Cuddalore and Porto Novo and along the west coast it forms on extensive beds from Muthalappuzha estuary in Trivandrum, Quilon, Alleppey, Cochin, Calicut to Kasargod, Mangalore, Karwar, Goa, Bhatia Creek, Malvan and the Gulf of Kutch (CMFRI, 2000). Now fishery for the green mussel exists in the region from Kollam to Kasargod and for brown mussel from Quilon to Kanyakumari along the Kerala Coast
