NOAA’s Office of Aquaculture
•Sustainable seafood
•Healthy marine ecosystems
•Create employment
•Support fishing communities, complement wild catch
•Restore and conserve marine and coastal habitat
Mission: Encourage the Development of Sustainable Marine Aquaculture
7
Current and Potential Research Partnerships
• Shellfish aquaculture• Modeling impacts • Alternative feeds• Stock enhancement
8
Marine Shellfish Farming
Quantify extraction of nutrients by shellfish• Coastal management
Genetics• Response to pathogens
and ocean acidification• NOAA Fisheries Northeast
Fisheries Science Center (Dr. Chris Brown)
• Early stages of collaboration with CAS on gene expression
• Possible collaboration with Sun Yat Sen University

Modeling Environmental Impacts
Objective 1: Evaluate models used for siting and operating aquaculture operations.
Status:• Model comparisons underway• 2011 modeling workshop
10
Modeling Environmental Impacts
Objective 2: Improve models
Status:• Working with private modelers• Partner with foreign
government and industry

Alternative Feeds Development
Objectives:1. Environmental2. Economics3. Human health
Status:• Initiative with USDA in 2007• Recently published report• Ongoing research

Stock Enhancement
Objectives: • Enhance natural populations• Rebuild depleted species• Assess impact of stock
stocking programs
Status:• Ongoing research at Mote
Marine Laboratory• Building collaboration with
China
