Aquaculture is frequently criticised for having a negative impact on the environment, which tends to overshadow its contributions to fighting hunger and alleviating poverty. This presentation reviews some of the needs to enhance the sustainability of the sector including knowledge of the basic biology of cultured species and immune systems of aquatic animals, the role of microflora in the production biology of aquatic systems, domestication, and integration of aquaculture practices with fisheries management. 

Over the past decade, new, environmentally sound technologies and resource-efficient farming systems have been developed, and the integration of aquaculture into coastal area and inland watershed management plans has been achieved, but are still not widespread. These aquaculture ecosystems are highly productive, semi-intensive enterprises that are water and land efficient, and are net energy and protein producers that follow design principles similar to those used in the fields of agroecology and agroecosystems.

This presentation builds on countries’ recent experiences to review the role of aquaculture in countries’ socio-economic growth and development, and discusses how institutional arrangements can lead to aquaculture’s enhanced net benefits to society. Aquaculture growth has recently been slowing down, and the sector is facing various resource, environmental, economic, knowledge and institutional constraints. Population growth, economic expansion and increasing preference for healthy food are expected to sustain the demand for aquaculture products.

This presentation reviews the role of emerging technologies in aquaculture. In genetics and breeding, the pace of advancement and innovation has been increasing exponentially. Improvements in aquatic animal health are coming from new technologies and improved management strategies. Nutritional research has focused on shifting from formulations based on ingredients to strategies based on nutrient availabilities and requirements. Production systems technology advancements are also contributing to sustainable industry expansion.

Risk and uncertainty associated with returns from investment in aquaculture to be an important constraint on aquaculture investment. Attention is given in this paper to identifying the factors that contribute to risk and uncertainty in aquaculture and methods of specifying the risk and uncertainty involved. It is found that there is limited practical scope for the extension of insurance markets in aquaculture, and most farmers will have to rely on other means to manage risk.

It is an undisputable fact that modern farming of carnivorous fish and shrimp uses more fish as feed than is produced as finfish or shrimps; that is, the ratio between fish used and fish obtained is higher than one. The author shows that industrial fishing for forage species brings about a net contribution of foodfish supplies, without causing a systematic collapse of the exploited forage species.

The main objective of this review is to understand the status of aquaculture-fisheries interactions associated with the biological, technological, social, economic, environmental and other aspects of aquaculture development. It will also examine how the interactions are addressed under the EAA. It cover aspects of scoping, prioritising, management tools and plans within the context of the elements of ecosystem resilience, social and economic issues and the integration of aquaculture with other sectors.

An essential element for the ecosystem approach to aquaculture is the use of virtual technology and decision-support tools, particularly if developing nations are to promote the key elements of aquaculture sustainability. We provide an overview of current and emerging issues and trends related to this topic over the past decade, an assessment of progress with regard to the expectations and commitments expressed in the Bangkok Declaration and conclude with some thoughts for the future.

Recently, on the advice of the members, a Strategy and Outline for Improving Information on Status and Trends of Aquaculture has been developed by FAO. The overall objective of the strategy is to provide a framework for the improvement of knowledge and understanding of aquaculture status and trends as a basis for policy-making and management, and to ensure development that is compatible with good stewardship of resources and the environment.
