About us

Two operations.
One commitment.

Sebastian Inlet Clams Inc. has operated from Melbourne Beach, Florida since 2002. We serve working growers across the southeast — with two distinct services we're careful never to blur.

Clam seed

We spawn clams.

Clam seed is produced on-site from our own broodstock, from larvae through set.

Eastern oyster

We grow Eastern oysters.

Spat is sourced from our partner hatchery. We grow to market size at our Melbourne Beach site.

Eastern oyster

Grow-out from partner spat.

We do not spawn oysters. We source Eastern oyster (Crassostrea virginica) spat from our partner hatchery and grow to market size at our Melbourne Beach site. We can grow Diploids and Triploids from Florida oyster broodstock, or Triploids only from Virginia broodstock.

Lead time is 8–12 months depending on season and cohort. Seasonal availability — inquire for current cohort status.

We are approved to ship to Georgia and maintain rigorous testing and sanitation protocols to ensure the highest quality product.

Environmental Stewardship

Supporting river restoration & coastal health

Beyond our core shellfish operation, Sebastian Inlet Clams Inc. is committed to the health and restoration of Florida's estuarine ecosystems. We partner with leading conservation organizations and research institutions to support projects that strengthen our coastal waters and the communities that depend on them.

Our commitment to coastal restoration

The Indian River Lagoon system is home to our operation and fundamental to our long-term success. Clean, healthy waters mean sustainable shellfish populations and thriving habitats. That's why we actively support river and coastal restoration efforts across Florida.
