Hard Clam Culture

Addressing Mortalities of Cultured Hard Clams in Cedar Key, Florida

Thermal Tolerance

Thermal Tolerances and Physiological/Behavioral Responses

Investigator: Shirley Baker, University of Florida (UF)/IFAS SFFGS Fisheries and Aquatic Sciences Program
Objectives: This study investigates the physiological responses of hard clams (Mercenaria mercenaria) to elevated summer temperatures, with a focus on oxygen uptake, behavioral stress indicators, and mortality. By examining how metabolism and chronic heat exposure intersect to challenge clam survival, this work aimed to inform research priorities, guide selective breeding efforts, and support the development of practical management strategies for shellfish aquaculture in a warming climate.
