This review covers aquaculture development in the Near East and North Africa. The main driving forces responsible for the expansion of the sector have included an increased public health awareness and interest in fish products, the passing of enabling policies driven by the need for consolidating domestic fish supply, compensating for declining capture fishery landings, strengthening the livelihood of rural communities and supporting food security programmes.

This review covers the status and trends in aquaculture development in North America including the nations of Canada and the United States of America. It is organised by thematic areas including the social and economic background of the region; resources, services and technologies; aquaculture and environment; markets and trade; contribution of aquaculture to food security, social and economic development; external pressures on the sector; the role of shared information, research, networking and governance.

Global aquaculture has not grown evenly around the world. There are marked intra and inter-regional and country variations in a number of areas, such as production level, species composition, farming systems and producer profile. This presentation reviews patterns in global aquaculture development, including regional development, species cultivated, industry composition, research effort, trade and governance issues. As the sector further expands, intensifies and diversifies it should make efforts to address sustainability in a transparent manner.

Plenary discussion of the regional and global aquaculture reviews presented at the Global Conference on Aquaculture 2010.

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. 

Sustainability of the sector implies technical feasibility, economic viability, environmental integrity and social licence. A sustainable aquaculture sector will benefit every member of society because of its associated invaluable environmental and social amenities. This review examines countries’ recent experiences and the role that aquaculture has played in improving socio-economic growth and development, and to discuss how governance instruments and effective partnership amongst stakeholders can lead to enhanced aquaculture’s net benefits to society.

There is a consensus that modern aquaculture has a business orientation, similar to any small or medium-sized enterprise. For resources to be invested, there must be an enabling economic environment and secure property rights. However, there must also be controls to curb short-sighted business behaviour that damages the ecology or society. This presentation examines aquaculture governance from a global perspective, looking at its current status and the role of governments and stakeholders.

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.

If the aquaculture sector is to maintain its current average growth rate of 8 to 10 percent per year to 2025, the supply of nutrient and feed inputs will have to grow at a similar rate. Feed-fed aquaculture production is largely dependent upon capture fisheries for dietary protein and lipid. Sustainability of the aquaculture sector is likely to be linked with the supply of animal and plant proteins, oils and carbohydrate sources for aquafeeds.

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.

Aquaculture is today considered the only viable option for meeting the increasing future demand for fish and seafood products. There are concerns that unconstrained sectoral expansion and intensification, coupled with its ecological and social impacts, globalisation and fluctuation of markets and resources, climate change may have undesirable impacts on the resilience of social-ecological systems. Aquaculture makes demands on, but also can provide a range of ecosystem services.

The aquaculture industry globally is characterised by an endemic cyclicity that goes beyond good or bad management and affects good companies and bad. This presentation aims to address the boom and bust phenomenon in the industry by examining some of the solutions that can help smooth out its cyclicity. The role of information gathering, management and analysis for decision making is discussed. The presentation includes a brief review of the global market for aquaculture products.

Certification schemes for both wild and farmed products are gaining market share in many developed country markets. In a not too distant future, aquaculture’s share of total supply for human consumption will rise to somewhere between 60 and 70 percent. This will have a profound impact on the sector’s ability to shape world markets but it will also challenge the sector’s ability to respond successfully to evolving consumer needs.

Aquaculture is likely to benefit greatly from the application of appropriate genetic and reproduction biotechnologies to increase food production, but the application of established genetic improvement methods in aquaculture is much less than in agriculture. The world’s wealth of aquatic biodiversity at the genetic, species and ecosystem levels provides great potential for the aquaculture sector to enhance its contribution to food security and meet future challenges in feeding a growing human population.

As standards, certification schemes and claims proliferate, their value is being questioned. Producers and producing countries in particular question whether these private standards and certification schemes duplicate or complement government work, especially in relation to food safety and animal health. The expert panel will review current practices and future trends in market-based quality standards and certification schemes in aquaculture, including international initiatives to promote transparent market standards for improved safety, quality and sustainability in aquaculture. 

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.

There is unprecedented growth in the demand for organic food and new areas of organic food production, such as fish, are proving increasingly popular. Today, several specific and relatively precise standards of organic aquaculture production (hatchery, feed, grow-out) and processing exist which aim at achieving optimal agro-ecosystems which are socially, ecologically and economically sustainable. Around 80 different organic aquaculture standards exist, both public as well as private.
