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
