It will be several years before aquaculture production will contribute substantially to total production.

Nonetheless, the culture of high value species of shrimp and fish could contribute significantly to export earnings during the next 5 to 10 years. Conducted primarily by government agencies, research and development are along the lines of increasing seed supply, establishing new culture techniques or improving older ones.

The Department of Fisheries DOF together with some private companies have ventured into the development and testing of artificial diets for the various cultured species using a variety of indigenous feed stuffs.

Major increases would come from bivalve mariculture mt , brackishwater ponds 36 mt freshwater ponds 46 mt and brackishwater cage culture 20 mt. At an annual per capita consumption of 32 kg some mt of fish is required for the projected of Coastal marine capture fisheries, the mainstay of Malaysia's fishsupply, has not shown any increase in landings over the last few years.

In fact in there was a decline of 3. This declining contribution of marine fisheries is compensated by an increase in aquaculture production. In , aquaculture contributed 51 mt to the total fish supply. Malaysia does not have a long standing aquaculture tradition unlike its neighbours in the Indo-Pacific. Even then, the industry has seen rapid growth in the last few years. Today there are 19 species of finfishes, crustaceans and shellfish cultured in the country.

This flexibility makes it possible to exploit especially in smaller ones. Many of the smaller reservoirs dry underused water resources to produce fish. A policy of regular, sound and sustained stocking II.

Low initial investment would greatly augment fisheries in such water bodies. The Relative to the cost of pond construction and its prime objective of cage culture in inland open water is associated infrastructure electricity, roads, water wells, stocking of reservoirs and culture of economically important etc.

Stocking with the right inexpensive. At low densities relative to pond surface fish species, using seed of appropriate size and introducing it acreage cages often do not require aeration or any at the right time are essential to optimizing fish yield from electrical source.

Cage materials are not especially reservoirs. Though 22 billion fish fry are produced every year expensive and many kinds of cages can be constructed in India, there is an acute shortage of fish fingerlings available with little experience. Where fingerings are available, transporting them to reservoirs usually incurs high fingerling III. Simplified cultural practices mortality. In this context, producing fingerlings in situ in cages Cages lend themselves to straightforward observation of also offers an opportunity for supplying stocking materials, the fish.

The observation of fish behavior, especially which are vital inputs towards a programme of enhancing fish feeding behavior, is critical to anticipating and avoiding production from Indian reservoirs Das et al. Cage culture operations Cage culture operation involves: Simplified harvesting Cages are usually harvested by moving them into shallow A. The stocking density of fish depends on the water, crowding the fish into a restricted area, and simply carrying capacity of the cages and feeding habits of the dipping the fish out of the cage.

Or, the cage can be lifted cultured species. For those species which are low in the partially out of the water so that the fish are crowded into food chain, stocking will also depend on the primary and a smaller volume, and then the fish dipped out.

This secondary productivity of the sites. The optimal stocking makes it possible to partially harvest fish from cages as density varies with species and size of fish and ensures needed for local niche markets or personal consumption.

Overwintering problems swimming, irrigation or livestock watering Masser [12]. It is difficult to over winter warm-water fish in cages. There is usually a high mortality rate because of bacterial 6. Constraints of cage culture and fungal diseases Masser [12]. Cages occupy space on the surface of water bodies and, if poorly positioned, may disrupt navigation or diminish the 7. Conclusion scenic value of the reservoir.

Poorly placed cages may alter Reservoirs for sure are a major fishery resource but they current flows and worsen sedimentation.

Inappropriately remain highly dispersed under a plethora of controlled regimes intensive or poorly managed cage culture may pollute the with variable governance and policy support. The reservoirs of environment with unconsumed feed and fish faecal waste, India can produce much more fish than current production causing eutrophication.

Based on average fish yields of over reservoirs, it During the summer or rainy seasons, cages may be damaged has been estimated that yields from these reservoirs small, by strong winds or flooding, but this risk can be avoided by medium and large is far behind the expected production properly anchoring batteries of cages in protected inlets away potential. Intervention of cage culture technology at large scale from strong currents.

Theft is rarely a problem in culturing fish through public private partnership PPP mode in these to fingerling size. As particular problems exist where intensive reservoirs can boost and bridge the gap between the current cage aquaculture is practiced for producing marketable fish or 93, tonnes production and expected production potential prawns, the technology has been used in Indian reservoirs only which is nearly 1 million tonnes and can contribute immensely to rear fingerlings, with limited use of supplemental feed.

About The Indian coastline can be delineated into 22 zones, based on the ecosystem structure and functions. The Indian boat type ranges from the traditional catamarans, masula boats, plank-built boats, dug out canoes, machwas, dhonis to the present day motorized fibre-glass boats, mechanized trawlers and gillnetters.

India's marine capture fish production ,increased from , tonnes in to 3. The bulk of the catch comprises oil sardines, followed by penaeid and non-penaeid shrimp, Indian mackerel, Bombay duck, croakers, smaller quantities of cephalopods, other sardines and threadfin breams.

CMFRI The inland capture fish production has increased from , tonnes in to , tonnes in , the major species being cyprinids, siluroids and murrels.
