The Blue Revolution refers to the significant growth and intensification of global aquaculture production—domestication and farming of fish, shellfish, and aquatic plants—from the middle of the 20th century to the present, particularly in underdeveloped countries. [1]
Aquacultural engineering is a multidisciplinary field of engineering and that aims to solve technical problems associated with farming aquatic vertebrates, invertebrates, and algae. [1] Common aquaculture systems requiring optimization and engineering include sea cages, ponds, and recirculating systems. [2]
Aquaculture has made up an increasingly large proportion of fisheries products produced in the Philippines, and there has been considerable research into improving aquacultural output. Philippine output in total makes up 1% of global aquaculture production, and the country is the fourth-largest producer of seaweed.
Intensive aquaculture has to provide adequate water quality (oxygen, ammonia, nitrite, etc.) levels to minimize stress on the fish. This requirement makes control of the pathogen problem more difficult. Intensive aquaculture requires tight monitoring and a high level of expertise of the fish farmer. Controlling roes manually
Three ways of defining a sustainable fishery exist: Long term constant yield is the idea that undisturbed nature establishes a steady state that changes little over time. . Properly done, fishing at up to maximum sustainable yield allows nature to adjust to a new steady state, without compromising future harves
Mariculture, sometimes called marine farming or marine aquaculture, [1] is a branch of aquaculture involving the cultivation of marine organisms for food and other animal products, in seawater. Subsets of it include ( offshore mariculture ), fish farms built on littoral waters ( inshore mariculture ), or in artificial tanks , ponds or raceways ...
Since the 1970s, the reform policies have resulted considerable development of China's aquaculture, both marine and inland. The total used for aquaculture went from 2.86 million hectares in 1979 to 5.68 million hectares in 1996. Over the same time span, production increased from 1.23 million tonnes to 15.31 million tonnes. [16]
A recent review of literature related to aquaculture in Canada concludes that there is a need for a national strategic plan to increase aquaculture production and to simplify the regulatory framework to reduce uncertainties and delays that have limited growth in the sector, while fostering greater involvement of First Nation communities.
