The eastern oyster, Crassostrea virginica, is a valuable benthic organism that plays a crucial role in ecosystem services and economically supports commerical fisheries and aquaculture industeries. In the Gulf coast of Texas, genetic studies have revealed significant insights into the population structure and hybridization patterns of these oysters. But research on the reproductive dynamics, viability, and genetics of the hybrid eastern oysters is limites, leaving significant gaps in scientific knowledge about these organisms. Therefore, evaluating hybrid eastern oysters is essential to determine their suitability for aquaculture in Texas and to inform science-based management and conservation strategies for sustaining the oyster population on the coast. The Gulf offers a unique environment along the Texas coast, characterized by varying salinity and temperatures gradient across multiple bay. Previous research indicated that eastern oyster in Texas are divided into two genetically distinct populations adpated to disntict environmental tolerances, including a genetic transition zone where naturally occurring hybrid oyster can be found. This project investigates the fertilization rates of larval hybid oysters. Hybridization is a tool for enhancing viable aquaculture production and requires an understanding of the broodstock genetic structure, as well as monitoring the progeny viability and fertility. The findings of this research will provide essential insights to inform viable selective breeding programs in Texas aquaculture and support local conservation strategies and fishery management plans for these important species.
