Multi-stakeholder processes (MSPS) in responsible fisheries management

Over the last decade, approaches to fisheries management and governance of fisheries resources have been undergoing a significant transition. The focus is shifting from the stock and species based management to conservation and ecosystem based strategy (EAF: Ecosystem approach to Fisheries Management

Perspectives on tuna purse seining using “Payao” in the Indian EEZ

Tunas and billfishes form important marine fishery important marine fishery resources in Indian EEZ. The current annual production of tuna and tuna like fishes from our coastal water is estimated as 52,297t (2001)

Pinctada magaritifera broodstock developed at CMFRI, Visakhapatnam

Broodstock of Pinctada margaritifera has been successfully developed in the marine hatchery at the Visakhapatnam Regional Centre of CMFRI. Five successful spawnings were achieved in the hatchery. However, due to high temperature and salinity fluctuations, larval rearing could not be completed. Successful spat settlement was achieved in the 3rd larval cycle. Spats collected from Lawson’s Bay were reared in the hatchery and the broodstock developed within a period of 18 months

Review of the Green Mussel Perna viridis Fishery of South West Coast of India

The green mussel, Perna viridis (Linnaeus1758) (Bivalvia, Mytilidae) is a commercially important species in India. Estimated total production from the mussel beds along the Malabar Coast during 1996-2008 was 89,593 t and the average annual production was 7,466 t. The total effort was 1,583,639 and the average annual catch per unit of effort was 56.6. Among the eight major mussel landing centres, Chaliyam (28%) recorded the highest production during 2003-2008 followed by Thalasseri / Thalayi and Moodadi / Thikkodi (19%), and Elathur / Kollam (9%). Effort was also highest at Chaliyam (24%) followed by Thalasseri / Thalayi (20%), Moodadi / Thikkodi (18%). The CPUE was highest for Koduvally, (71) followed by Chaliyam (63). The average price per 100 Kg shell-on mussel during 1996-2008 was € 9.9 (INR 617). This fishery sustains the livelihood of 1,551 mussel pickers along the South West Coast. The fishery is dependent on the wild of spat fall whose annual density is influenced by the south west monsoon. The distribution, fishery and management of this fishery along the south west coast of India are described

Proximate composition of the surf clam Mactra violacea (Gmelin 1791)

The surf clam Mactra violacea (Bivalvia: Mactridae) is a fairly large marine clam with high meat content. These clams are found in the surf zone of exposed sandy beaches. The proximate composition of M. violacea was studied. Moisture, crude protein, crude fat, acid insolubles and ash were estimated. The protein content of M. violacea was estimated as 11.9 %, fat 1 %, ash 3.2 % and moisture 80 %. The surf clam is a good source of protein and minerals and has low fat content. The nutritive value is high and comparable to other shellfishes

Seed production of gastropods- Winter School on Recent Advances in Breeding and Larviculture of Marine Finfish and Shellfish

Marine gastropods are exploited all over the world for subsistence as well commercial reasons. Gastropods are used as food; they are a good source of protein and protein rich products. They are usually served as soup in many Japanese, Korean and Chinese restaurants. Commercially they in high demand in shell craft production such as lampshades, curios, fashion accessories like buttons, mother of pearl flakes from powdered scrap, formulation of lacquers and shampoos etc. The widespread use has often led to indiscriminate exploitation and it is important this resource be utilized in a sustainable manner. In this context, seed production of many commercially important gastopods has been successfully developed in hatcheries

Vulnerable marine ecosystems (VMEs)

Oceans cover 70% of our planet and represent over 95% of the biosphere. Marine and coastal habitats include coral reefs, mangrove forests, sea grass beds, estuaries, hydrothermal vents, seamounts and soft sediments on the ocean floor deep below the surface. Apart from source of food, the ocean is one of the largest natural reservoirs of carbon. It stores about over 15 times more CO2 than the terrestrial biosphere and soils, and plays a significant role in climate moderation. Deep-seabed habitats host between 500,000 and 10 million species. Deep-sea life is essential to life on Earth because of its crucial role in global biogeochemical cycles, including nutrient regeneration and oxygen. Oceans are seriously underprotected, with only about 0.8% of the oceans and 6% of territorial seas being in protected areas. About 80% of world fish stocks, for which assessment information is available, are fully exploited or overexploited and thus require effective and precautionary managemen
