The overall goal is to evaluate, demonstrate, and develop aquaculture of the sunray venus clam, Macrocallista nimbosa, as a new species to diversify the bivalve culture industry in Florida. In our 2006-08 FLSG project, we successfully spawned and cultured larvae through metamorphosis and hatchery phase using techniques similar to those for hard clam hatcheries.
We hypothesize that nursery and grow-out of the sunray clam to a harvestable size may be accomplished using culture methods similar to those employed by the Florida hard clam industry. Therefore, the objectives of this proposal are to:
- establish methods for land-based nursery culture of sunray venus clams,
- compare field culture methods for nursery and grow-out of sunray venus clams
- determine salinity and temperature preference of nursery and grow-out sized sunray venus seed clams
- evaluate shelf-life and “degritting” of live product,
- examine alternative markets for a shucked meat product, and
- characterize the economics for culturing sunray venus clams.
