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.

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.
Our Projects
Our Projects
CTSA’s research, extension, and education efforts have resulted in the growth of the aquaculture industry in the Pacific Islands and beyond. The Center’s impacts are wide-ranging and include disease mitigation, sustainable aquatic feeds development, and propagation of new species, just to name a few.
Farmer Outreach
Farmer Outreach
Without aquaculture farmers, there would be no aquaculture industry. To help support these critical links in the production chain, CTSA has created the Farmers Outreach section of this website. This section features information on research, extension, and outreach resources for Pacific Island Farmers.
