Description It is widely accepted that the catch and catch rates of many marine fishery resources are
declining mainly due to overcapitalization and overexploitation.. In this context, it is very much
relevant to resort to resource augmentation methods through mariculture and allied techniques to
enhance the seafood production. Mariculture is the farming and husbandry of marine plants and
animals in marine environments. On a global basis, aquaculture is the fastest growing animal food
production sector with per capita supply increasing from 0.7 kg in 1970 to 7.8 kg in 2006 with an
average annual growth rate of 6.9%. Most of the global aquaculture production of fish, crustaceans
and molluscs continues to come from inland waters (61% by quantity and 53% by value). Mariculture
contributes 34% of the total aquaculture production and 36% of the value. While much of the
marine production is contributed by high value finfish, relatively low priced mussels and oysters are
also widely farmed. While the overall share of farmed fish in marine finfish production has stayed
much low, for the species that are farmed, cultured fish dominates the market. This is the case of
Asian seabass, gilthead sea bream, red drum, bastard halibut and cobia. It is also a fact that for
such species, the quantities now produced by aquaculture are often substantially higher than the
past highest catch recorded by capture fisheries. In the last decade, salmonids have overtaken
shrimp as the top aquaculture group in Latin America and the Caribbean as a result of outbreaks of
disease in the major shrimp producing areas (FAO,2009).
Aquaculture in the Asia-Pacific region has been growing steadily over the last few decades and
to satisfy the demand of the local and export markets, many countries are expanding their aquaculture
activities in the sea, including offshore areas where competition is less. Mariculture in this region is
exceptionally biodiverse and relies on many species and hence the nature of mariculture is rapidly
changing in this area (Rimmer, 2008). Some of the countries like China, Vietnam, Australia, Indonesia,
and Japan. Korea DPR, Korea Rep, Malaysia, Phillippines, Thailand are much ahead in mariculture
in this region and agencies like NACA should take intergovernmental regional programmes so as to
develop mariculture in the region as a whole.
