Coastal Aquaculture and Mariculture (2+1)

Unit 1 - Shore based aquaculture and mariculture

1.1.4. Global aquaculture production - by environment

• Freshwater production contributed to 59.9 percent by quantity and 56.0 % by value in 2008
• .Seawater ( in the sea and also in the ponds) accounted for 32.3 percent by quantity and 30.7 percent by value (both plants and animals). Majority of this production comes from the farming of seaweeds. While, low volumes of high value finfish, crustaceans and abalones are grown in seawater; low value oysters, mussels, clams and cockles are grown in large quantity.
  
• Brackish water aquaculture produced 7.7 percent of the total aquaculture production by quantity but a high value of 13.3 percent reflecting the dominance of more valued crustaceans and fin fish produced in this environment.
