An ecosystem approach to aquaculture (EAA) strives to balance diverse societal objectives, by taking account of the knowledge and uncertainties of biotic, abiotic and human components of ecosystems including their interactions, flows and processes and applying an integrated approach within ecologically and operationally meaningful boundaries.

The EAA should apply at the farm level, at the aquaculture geographic zone; at the industry and commodity level; and at the macro level (policy formulation). The EAA should improve aquaculture sustainability through facilitating nutrient cycling while minimizing negative impacts at different intensity levels for example through polyculture/integrated aquaculture (eg. fish and mussels, fish and seaweeds) also allowing a broader use of ecosystems through enhancing or coupling with other activities such as fisheries (eg. aquaculture based fisheries) and agriculture (eg. rice fish farming).

]]> There will be several expert workshops mostly focusing on the develop of guidelines for policy making.

A new GESAMP working Group on Ecosystem Approach to Offshore Mariculture will hold several meetings in the next two years to develop and propose some guidelines for EAA offshore.
There are several regional and global reviews underway to provide information for analysis and discussion in these workshops; including reviews of the present situation of freshwater and marine aquaculture for major commodities and within potential EAA framework.
There are also some major reviews on integrated coastal mariculture as a major tool within the EAA perspective.

Various publications are foreseen including Proceedings of the workshops on EAA, Guidelines, GESAMP reports etc.

]]> Aquaculture is now one of the fastest growing food producing sectors, but it is being criticized for creating adverse environmental impacts. However all food production systems have environmental costs and therefore is important to provide information and methodologies which could be used to make development decisions that take into account these. This will help determine where public and private sector investments should be made to encourage the optimisation of food production at the national level; optimization refers to economic viability, environmental sustainability and social acceptability.

]]> Alien species, are a proven method of increasing production and value from aquatic ecosystems. However, they are also recognized as one of the most significant threats to aquatic biodiversity. Policy makers must balance these benefits and risks to decide when an introduction may be appropriate. Toward this end FAO has developed a framework for the responsible use and control of alien species in fisheries and aquaculture. The framework consists of:

The CCRF, an overarching agreed international instrument;
International guidelines and codes of practice such as the ICES Code of Practice on the Introductions and Transfers of Marine Organisms, and Asia Regional Technical Guidelines on fish health;
An information source, the Database on Introductions of Aquatic Species;
A means to deal with uncertainty, a precautionary approach;

The Department has established a CD-ROM, Introduced Species in Fisheries and Aquaculture: information for responsible use and control, available through the service or FAO distribution and sales.
