The open offfshore aquaculture, together with polyculture, was one of the main subjects in the 1st Korea-U.S. Joint Coordination Meeting for Aquaculture Cooperation held in Busan, Republic of Korea, April 15-16, 2002, the Korea-U.S and Meeting for Scientific and Technical Cooperation convened in Honolulu, Hawaii, USA, October 9-12, 2002. Following the two meeting, Dr. Yoon Kim, co-chair of Korea-U.S. Joint Coordination Meeting for Aquaculture Cooperation, and Dr. C. R. Ryu, a professor in department of ocean engineering at Pukyung National University and Korean Sea Grant Project leader, hosted a meeting specialized for the successful installation and development of offshore aquaculture in Korea. The participants of the meeting were people from universities, aquaculture industry, policy maker, and related business. In the meeting, Dr. Yoon Kim and Dr. C. Ryu explained the previous two meetings and the concept of the open offshore aquaculture. A total of 39 persons attended at the meeting.
Following the 1st meeting specialized for the successful installation and development of offshore aquaculture in Korea, the second meeting also hosted by Dr. Kim and Dr. Ryu was held in March 14, 2003 in the Aquaculture Department of National Fisheries Research and Development Institute. Dr. G. S. Yoon, a professor of department of ocean engineering of Pukyong National University, presented a mooring system of floating pen cage following Mr. Langley Gace who gave a presentation about installation, operation, and net of standard offshore aquaculture cage (Sea Station 3000). After the presentations, dialogue between the presenters and attendants was made about Korea-US priorities and time line relative to offshore aquaculture technology which were prepared in the Hawaii meeting. The priorities discussed are as follows:
1. Site selection criteria
Bottom topography/sediment type/depth
Logistics/access (infrastructure)
Arrangement of site components
2. System requirements
Feed delivery to system, in particular submerged cages
Controlled harvesting, incremental harvesting
Size grading requirements followed by selective harvesting
Biofouling control (including anti-foulants; net cleaner (robotics))
Divers health management
Monitoring systems (including environment, facility security/management)
Containment
Fish transport and acclimation
Logistical support and vessel design
Large scale demonstration
3. Biological considerations
Species selection and diversity
Genetic management
Stock identification and tagging development
Stocking sizes and technologies
Nutrition/feed requirements
- fish meal reduction
- diversification
- by-product utilization
Fish health management/fish disease diagnosis and control
Fish quality
Human health feed health assurance/positive components
Hatchery technology and species availability
Polyculture
Reproductive management
Biological interactions/habitat enrichment/optimization
Species behavior and modification and cage design to optimize
4. Environmental considerations
Nutrient enrichment of water column (pros and cons)
Organic enrichment of sediment
Biological interactions
-fish aggregating devices (FADs), marine mammals, as habitat enhancement
Ecological interactions (escapees and disease transfer)
Impacts of human origin
Feed composition (raw feeds vs. extruded feeds)
Seed stock source
Medications and vaccines
Development of a Code of Conduct and a best management plan (BMP)
5. Risk assessment
6. Markets and economics
Exchange of production statistics in fisheries and aquaculture
Market size/product selection/species
Value-added/product form
Consumer preference
Scale of production
7. Regulatory considerations
Size of fish regulated by wild harvests
After the meeting, Mr. Langley Gace and Dr. Qtae Jo, a aquaculture scientist in Aquaculture Department of National Fisheries Research and Development Institute, visited two suggested candidates for the instalation of Sea Station 3000, in Korea. The two persons flied to Jeju Island, one of the two candidate of cage installation. In Jeju, Mr. Gace presented same topic as presented in Busan at Jeju Marine Institute,
Jeju.
Sea Grant Planning Meeting
Two 2003 Sea Grants on offshore aquaculture were accepted from MOMAF. Two professors, Dr. C. R. Ryu and Dr. G. S. Yoon, responsible for the Sea Grants, hosted a Sea Grant Proposal Meeting held in Aquaculture Department of NFRDI in June 11. In the meeting, Dr. Yoon Kim, a department head, and Dr. K. S. Min, a division head, decided to provide the two professors with a space and facilities for their laboratory experiments for offshore aquaculture at Aquaculture Department of NFRDI. Two NFRDI research scientists, Dr. Young Ju Jee and Dr. Qtae Jo were decided to help their laboratory works out.
