Aquaculture production has continuously increased during the past two decades. In 1998, 26.4% of total world fisheries came from aquaculture, up from less than 10% in the late 1970s. If aquaculture production is to continue to grow, it is important to learn what technological advances account for significant increase in aquaculture production and to understand the challenges that may arise for the industry in the years ahead.

A workshop funded by the National Oceanic and Atmospheric Administration (NOAA) was held in Honolulu, Hawaii, USA, 12-15 February 2001, to review past challenges and discuss possible future challenges. Speakers from Canada, China, Greece, Japan, Taiwan, Thailand, and the USA were invited to present technical solutions to challenges faced in the past by different aquaculture production systems, then use the lessons learned to predict what technological improvements or innovations will be needed to meet the challenges to aquaculture production in the future in their respective countries. Aquaculture production systems for marine shrimp, turbot, halibut, Japanese flounder, eel, milkfish, tilapia, carp, channel catfish, European seabass and seabream, trout, yellowtail, and salmon were discussed during the workshop.

Invited speakers at the workshop identified the top 10 major threats to aquaculture expansion in the future:

  1. Competition with other users for resources
  2. Limitations of feed
  3. Desirable product quality
  4. Spread of disease
  5. Compliance with environmental regulations
  6. Public acceptance
  7. Ability to obtain desired traits through genetic improvement
  8. Overproduction (e.g., limited markets, lower prices)
  9. Adverse environmental conditions caused by other industries
  10. The gap between researchers and industry

This presentation will briefly summarize the reports of the invited speakers and the discussions that took place at the workshop.
