Shellfish Farming

NAICS 112512 · Animal Production and Aquaculture · SBA size standard: $3.75 million average annual receipts

Shellfish farms grow oysters, clams, mussels and scallops in leased coastal waters using bags, trays, longlines or bottom culture. Operators manage seed purchases, site permits, seasonal planting and harvesting cycles driven by tides and water temperature, track growth to market size, maintain gear inventory, schedule vessels and crews, coordinate with buyers or direct-to-market sales, and handle food-safety logs, depuration records and lease compliance paperwork.

What makes this business different

  • Tide, weather and water-quality windows that dictate when crews can work on leases
  • Multi-year crop cycles with staggered plantings and harvests by species and size
  • Seed and spat purchases timed to seasonal hatchery availability and nursery stages
  • Gear and equipment maintenance: bags, cages, longlines, buoys and vessels
  • State and local leases, permits, water-quality certifications and harvest tags
  • Food-safety and traceability records including water sampling, Vibrio plans and temperature logs
  • Direct wholesale to restaurants, distributors or on-farm sales with rapid cooling and live transport
  • Biosecurity and predator control that must be logged per lease site

Workflows

Seed and spat purchasing

Starts when: End of previous nursery cycle or quarterly by species

  1. Review current inventory of seed by size and species against planting forecast
  2. Draft purchase orders for hatchery or nursery suppliers based on expected survival rates
  3. Schedule delivery or pickup dates to match tidal planting windows
  4. Record receipt, acclimation and nursery placement
  5. Update inventory sheets with batch numbers for traceability

Watch for: Seed must arrive during specific temperature and salinity windows; Survival rates vary by supplier and require historical tracking

Planting and grow-out scheduling

Starts when: Optimal tidal and water-temperature windows

  1. Check weather, tide charts and water-quality reports for safe working days
  2. Assign seed to specific lease sites and gear types using the construction-scheduler
  3. Create daily task lists for crews including site access and gear deployment
  4. Log planting density, date and batch for each bag or longline
  5. Flag sites needing predator netting or anti-fouling treatment

Watch for: Work limited to low-tide windows that shift daily; Gear placement must match lease coordinates and depth restrictions

Gear and vessel maintenance
