Study Notes
What is Integrated Multi-Trophic Aquaculture (IMTA)?
- IMTA involves farming two or more aquatic species from different trophic levels together to improve efficiency, reduce wastes, and provide ecosystem services like bioremediation.
History of IMTA
- 2200-2100 B.C.: You Hou Bin integrated fish with aquatic plants and vegetable production in China.
- 889-904: Liu Xun described the theory of mutualism in grass carp/rice paddies culture and integration of fish and fruit production.
- 1639: Xu Guangqi described irrigation rotation of fish and aquatic plant production, and integration of fish with livestock.
- 1975: Ryther, Goldman, Gifford, Huguenin, Wing, Philip Clanner, and Lapointe developed the "integrated waste-recycling marine polyculture systems".
- 1999: Troell, Rönnbäck, Halling, Kautsky, and Buschmann reviewed the advantages and limitations of closed circulation systems derived from the early prototype of IMTA.
- 2004: Thierry Chopin and Jack Taylor coined the term "Integrated Multi-Trophic Aquaculture".
Concepts Behind IMTA
- The solution to eutrophication is not dilution, but extraction and conversion through diversification.
- IMTA follows the principles of the Ecosystem Approach to Aquaculture (EAA), which aims to integrate aquaculture within the wider ecosystem.
- The three principles of EAA are: (1) aquaculture development and management should take account of ecosystem functions and services, (2) aquaculture should improve human well-being and equity, and (3) aquaculture should be developed in the context of other sectors, policies, and goals.
Advantages of IMTA
- Increased efficiency through diversification of income streams and reduced risk of crop failure.
- Improved resilience through a more balanced ecosystem, reducing disease outbreaks and environmental problems.
Disadvantages of IMTA
- Lack of open water leasing policies and absence of clear policies hinder implementation and exacerbate environmental threats.
- Implementation hurdles due to lack of national aquaculture plans and integrated coastal zone management.
- Coordination challenge among different operators.
- Higher investment required for integrated farming in open sea.
- Biofloc and RAS systems can be used in IMTA to improve water quality and minimize the use of natural resources.
