special symposium entitled "The Aquaculture Paradox: Does Fish Farming Supplement or Deplete World Fisheries?" was conducted at this year's American Association for the Advancement of Science (AAAS) Annual Meeting. Organizers included Roz Naylor, Stanford University; Rebecca Goldburg, Environmental Defense; and Meryl Williams, International Center for Living Aquatic Resources Management.
The symposium introduced controversial issues in the aquaculture arena. Topics included the use of wild fish as feed for the farming of carnivorous species, the impact of habitat modification for aquaculture applications, wild seed stock collection, effluents, exotic species, introductions, and pathogen invasions. The session analyzed marine and freshwater aquaculture throughout the world. Several of the focus questions included:
- What are the overall impacts of aquaculture activities on environmental systems worldwide?
- Does aquaculture enhance or diminish the available fish supply?
- What changes in current practices could ensure long-term sustainability?
The session presented scientific and policy issues and brought up solutions to challenges facing aquaculture production. Jason Clay's presentation titled "Shrimp aquaculture and the environment: Lessons learned about best and worst practices" incorporated findings of CRSP researcher Claude Boyd. This year's AAAS meeting took place February 15 to 20 in San Francisco, California.
