Mission
Educate the public, government, and industry stakeholders about the potential and benefit of aquaculture products to improve Hawaii's ability to be self-sufficient and self-sustaining; to expand understanding about aquaculture's contribution to the conservation of Hawaii's limited natural resources; and to promote Hawaii's aquaculture products and services locally, domestically, and internationally to confirm Hawaii's reputation as a center of excellence for applied research and aquaculture technology.
Program accomplishments
- At the end of 2025, HAAA received a $50,000 grant from Ulupono Initiative to conduct a statewide aquaculture baseline survey. The survey involves compiling information from existing sources about the current scope, future potential, and producers' concerns regarding Hawaii's aquaculture and aquaponic industries. To fill in gaps in currently available information, interviews will be conducted with aquaculture and aquaponic producers, academic researchers, and government personnel. A final report will be prepared and provided to Ulupono Initiative, which in turn will submit the report to Hawaii's Department of Agriculture and Biosecurity and to State legislators to help develop forward-looking policies regarding aquaculture and aquaponics. Since the funding was received in late December 2025, no expenses were accrued for this project until 2026, so the amount reported on this form is 0.grants $50,000
- Providing educational and networking opportunities for HAAA's members and the public: HAAA sends out approximately 100 emails annually to its membership notifying them of new developments locally and nationally that affect aquaculture and aquaponics; of local workshops and other events that may be of interest; and of opportunities for employment. HAAA participated with a booth at the annual Agriculture Appreciation Day at Hawaii's State Capitol, helping to educate Hawaii's legislators about the benefits of Hawaii's aquaculture and aquaponic production. HAAA also celebrated its 50th anniversary as an organization with a planning and networking session followed by entertainment; the event brought together more than 70 producers, researchers, and legislators and staff.Expenses $5,604 · grants $500
