2022 Census of Agriculture

The 2022 Census of Agriculture is right around the corner and USDA NASS is making every effort to count all aquaculture producers in the United States. If you produce any aquaculture products and want to make sure that you are counted in the 2022 Census of Agriculture and the 2023 Census of Aquaculture, please sign up your operation.

Center for Tropical and Subtropical Aquaculture

One of five Regional Aquaculture Centers under NIFA, USDA

The Center for Tropical and Subtropical Aquaculture (CTSA) is one of five regional aquaculture centers in the United States established by the U.S. Department of Agriculture. The regional aquaculture centers integrate individual and institutional expertise and resources in support of commercial aquaculture development.

CTSA was established in 1986 and is jointly administered by the University of Hawai’i and the Oceanic Institute of Hawai’i Pacific University. The CTSA administrative office and staff are located on the University of Hawai’i Campus in Manoa.
