Glory of Mussel Culture Stimulates Entrepreneurship in Goa
Goa has an enormous brackishwater resource potential with an area of 330 ha for augmentation of coastal mariculture. However, the lack of awareness about the relevant technology among the people was found to be the major cause of poor growth of this sector. Being a tourist destination and majority of population consuming fish, there is a high demand for finfish and shellfish in Goa.
Green Mussel, Perna viridis, locally known as “Xinanneo” is found to be a major shell fish species under the group bivalves relished by the Goan people. A single piece of the mussel of size of 40-60 mm with an average weight of 30-33gm costs around Rs. 5 to 8 in the retail markets of Goa. This species grows well in brackish waters with a salinity ranging from
25-32 ppt. Hence, the resource augmentation through farming techniques in the unutilised brackish water areas of Goa can only meet the required demand for the same in future. Mussel farming using various techniques like Rack, Raft and longline are robust ecofriendly methods and there are no extraneous inputs like feed, fertiliser and other materials to the culture system. Thus, the maintenance of the culture system is also comparatively easy. Usually the culture period starts from November or December after the adequate spat (seed) settlement along the coastal areas and subtidal beds. It will extend up to May with a period of about 6-7 months. However, harvest will be done before June since the monsoon will retard the salinity and affect the mussels.
