Mussel Culture

Mari culture of bivalves greater importance in meeting the increasing protein demands of the human population. Bivalve groups such as oyster, mussel and clam are the most important cultivable organisms all over the world. Of these, P.viridis and P.indica forms the most dominant cultivable species. The Central Marine Fisheries Research Institute (CMFRI) has developed eco-friendly techniques for mussel culture. Recently, CMFRI has taken up efforts to popularize mussel culture in all coastal districts of Kerala

Integrated farming of mussel and edible oyster by self help groups in Sathar Island, Ernakulam District, Kerala

Among the maritime states of India, Kerala with a coastline of 590 km and 39,139 sq km of continental shelf area enjoys the distinction of being the foremost marine producer and exporter. The potential yield of the area up to 200 m depth has been estimated to be about 8 lakh tonnes

New trends in farming mussels and edible oyster in India

The Central Marine Fisheries Research Institute (CMFRI) by setting up demonstration farms and conducting training programmes to fishers was able to popularize bivalve farming in Kerala State. Simultaneously, through interactions with the State government officials and members oflocal governing bodies, project proposals on oyster and mussel farming were recognized .as financially viable schemes for rural development and self-employment. Since 1995, edible bivalves like the Indian backwater oyster, Crassotrea madrasensis and the green mussel, Perna viridis are farmed on a commercial scale in the estuaries of Keral

Clam fisheries of Vembanad Lake, Kerala with observations on the socio economic conditions of the clam fisheries

Vembanad Lake is the main estuary system which harbours rich resources of clams along the south west coast of India. Villorita cyprinoides) is the main resource followed by Meretrix cata, Paphia malabarica and Suneta scripta.Annualy about 31650 tonnes of clams are harvested and out of which 31430 tonnes is contributed by the black clam

Population characteristics and some aspects of the biology of oceanic squid Sthenoteuthis oualaniensis (Lesson, 1830)

An analysis of 15 specimens of the oceanic squid Sthenoteuthis oualaniensis caught by hooks and lines from the Arabian Sea showed that the growth pattern was isometric with the length-weight relationship W = 0.0276 L"'. The von Bertalanffy growth parameters estimated were L_ = 49.1 cm; K = 0.83 yrl and to, -0.06 yr. Other population parameters such as optimum length for exploitation, length at maturity and natural mortality rate were also estimated. Relative fecundity was 125 no. /g body weight. The egg diameter ranged from 0.7 to 0.9 mm. The scope for exploitation of the oceanic squid is discussed.

Mabe Pearls : A simple way to value added pearls (Pamphlet)

The Central Mari ne Fi sheries Research Institute (CMFRI), Cochin, the premjer fisheries research institute of the coun tr)', developed the technology for cul tured marine pearl production during the early 1980s. Now, scientists of the insti tute have succeeded in perfecting a simple technique for value added marine pearls, called mabe (mah-BAY) pearls. A mabe pearl is a dome shaped or image pearl produced by placing a hemisphe re or miniaturc image against the side of the oyster shell interior. The result is an exquisite pearly nacre coated miniature image of anything dear to humans like Ganesha, Saraswathy, Lakshmi, Ashoka, Crescent and Holy Cross etc. These miniature images can be made into pendants, eardrops and rings. A fine quality Mabe pearl of 10 mm size can easily fetch more than US$ 100 in international markets and an average of Rs. 1000 in local markets

Checklist of marine bivalves and gastropods off Kollam, Kerala

Species diversity of any region can be illustrated by means of an available checklist. It provides an overview of the species that have been recorded. and can be considered to understand the local fauna. Fortnightly surveys were carried out to collect the shell-molluscs samples during 2012 - 2014 period from the by-catch of shrimp/fish trawlers landed at Sakthikulangara-Neendakara Fishing Harbour, Kollam. Collected bivalves and gastropods included both empty shells and living animals. Collected shells were brought to the laboratory and placed in freezer for 24 hours. This would liquefy the mollusc body and allowed easy extraction with a strong jet of water
