Network of Aquaculture Centres in Asia-Pacific

Environment and Sustainability

Global population is forecast to reach around 9 billion by 2050. To feed the world, global agricultural output must increase by around 60% from present levels. This must be achieved against a background of increasing competition for natural resources such as water, feed ingredients and farming sites.

Maintaining environmental integrity while massively increasing food production will require farming systems to reduce their unit production environmental footprint. Many farming practices that are regarded as sustainable today will not be acceptable when scaled up. Sustainable intensification of aquaculture means doing more with less. The Environment and Sustainability Programme aims to help aquaculture become a more efficient user of natural resources, both in terms of farm productivity and environmental efficiency.

The programme develops better management practices for major aquaculture farming systems, and promotes aquaculture as a secondary or additional use of water resources. The programme focusses on practical interventions that can be directly achieved by small-scale farmers in a developing country context.

Key activities

Key activities of the programme are:

  • Development of better management practices for key aquaculture production systems.
  • Organising small-scale farmers into associations to facilitate cluster-based approaches to extension.
  • Development of culture-based fisheries as a secondary use of water bodies.
  • Development of strategic policy frameworks to guide governments and development agencies in promoting sustainable intensification of aquaculture.

Nursery management of grouper: A best-practice manual

This manual provides practical guidelines for those engaged in the nursery culture of groupers in Indonesia as well as elsewhere in the tropics. It provides information on husbandry of groupers in the nursery phase, to reduce losses due to disease and cannibalism, and thus to increase the profitability of grouper nursing. The guidelines are derived from outcomes of ACIAR-funded research as well as other published information on grouper nursery management.

Public Sector Regulatory Systems for Ecosystems Based Management of Aquaculture - a GAP Analysis Tool

This document presents a tool in the form of an audit table that can be used to broadly screen and identify gaps in the management systems of government agencies responsible for regulating aquaculture. These gaps, once identified, can be a first step toward building regulatory frameworks that can better deliver on jurisdictional ecologically sustainable development and ecosystems approach to aquaculture objectives. The end product of an assessment is a report for consideration by decision makers.

Aquaculture sustainability: Towards 2030

To provide food to the world’s population in 2050, it has been estimated that agricultural output, primarily from crops, livestock and fisheries, including aquaculture, must increase by 60 percent. Intensification of aquaculture is inevitable in the face of increasing demand, limited land areas, and improved technology. Whether we are able to accomplish this in a sustainable manner will depend on global governance and stewardship as much as on technological progress.

Feeds and feeding: Problems and plausible approaches in intensification and attaining sustainability

Improved feed management represents a critical component in the sustainability equation, and the industry’s responses, particularly in respect to the use of fish meal and fish oil, will determine whether feeds are likely to become a limiting factor in attaining sustainability. In order to continue to contribute to global food fish supply, the sector will have to intensify. The presentation discusses plausible means of reducing dependence on these commodities as well.

Marine capture fisheries as a source of food for aquaculture in the Asian region

Asian aquaculture is the world’s major user of fishmeal, and 86 percent of fishmeal used in Asia (excluding China) now goes to aquaculture. With no new sources of fish, many argue that we have already reached the limit in coastal trawl fisheries. There is a shift away from using fresh fish directly as feed, towards pelleted feeds. The Asian aquaculture industry will be affected as supplies tighten and costs rise.
