Up to 50 percent of the northern hard clams, M. Mercenaria DIE in the gulf of america because of prolonged high water temperatures

Southeastern Seaproducts Inc. received a $307,468 Project Grant from the National Institute of Food and Agriculture (NIFA) under the Grants for Agricultural Research, Special Research Grants program (CFDA 10.200), effective September 1, 2025 through August 31, 2027. The award funds research and development activities evaluating the economic viability and market feasibility of hybrid hard clams, which are produced by crossing the commercially available Mercenaria mercenaria clam with the heat-tolerant native Mercenaria campechiensis species. The project addresses critical challenges facing Northern clam growers, including up to 50 percent mortality rates due to prolonged high-water temperatures and market access limitations imposed by state regulations restricting the sale of clams smaller than one inch in diameter—a market segment currently dominated by foreign imports.

The primary deliverables include comprehensive economic viability assessments, consumer acceptance studies, pricing model development, and competitive analysis of hybrid clams against imported alternatives. By demonstrating the commercial and economic potential of temperature-resistant hybrid clams that comply with existing size regulations, this research is intended to create new market opportunities, generate employment in coastal fishing communities, and contribute to reducing the U.S. seafood trade deficit. Research activities will be conducted at the awardee's facility in Melbourne, Florida.

A second problem, laws in northern states prohibit the sale of M. Mercenaria clams less than one inch in diameter, a huge market dominated by foreign imports. These laws protect againstgrowers in the gulf of america and in georgia have demonstrated the viability of growing hybrid clams which are a cross of the commercial clam M. Mecernaria with a better adapted native clam M. Campechiensis, the southern M, this proposal evaluates the economic viability of hybrid clams, assesses consumer acceptance, develops pricing models, and examines their competitiveness against imports.new markets for hybrid clams with better survival will create jobs and improve economics to revitalize fishing coastal towns and assist with closing the seafood trade deficit.
