What Is Regenerative Shellfish Farming
A definition grounded in operational decisions, not aspiration.
This page defines regeneration in the specific context of shellfish farming. It does so by naming the practices that qualify, the practices that do not, and the tradeoffs that follow. Regeneration only has meaning when it constrains behavior.
Working definition
Regenerative shellfish farming is aquaculture that improves the long term health and function of an estuarine habitat while producing food, and does so through methods that minimize physical disturbance, avoid persistent materials, and adapt to environmental limits rather than overriding them.

What Regeneration Requires in Practice
In shellfish farming, regeneration is not theoretical. It shows up as a series of operational constraints that shape how food is produced.
Regenerative shellfish systems do not rely on dredges or dragged gear that resuspends sediment, disrupts benthic structure, or resets the bottom each season. If harvest depends on mechanical disturbance, the system is extractive by definition.
Where shellfish interact with the substrate, contact is deliberate and minimal. The goal is stability, not access. Gear is selected to reduce churn rather than maximize convenience.
Regenerative systems avoid disposable plastic materials that remain in the environment after their functional life. Persistent materials shift risk downstream to the habitat.
Regenerative farming accepts variation in tides, sediment, and biology. Methods are adjusted to the system instead of forcing uniformity through intervention.
Practices that require eelgrass removal, predator exclusion netting, or repeated clearing fail the regenerative test. If production depends on suppressing recovery, it is not regenerative.
Regenerative operations accept harvest closures, slower growth, and variability as signals, not obstacles. Output follows conditions, not the other way around.
Boundary example
Why We Do Not Farm Manila Clams
Most Manila clam operations rely on plastic predator exclusion netting and aggressive eelgrass removal to increase short term yield and simplify harvest. These methods require continuous habitat suppression.
Under this definition, a system that depends on suppressing eelgrass, covering the bottom in plastic, or repeatedly clearing habitat cannot be regenerative. That boundary is intentional.

- Regenerative shellfish farming requires minimizing physical disturbance of the benthic environment.
- Dredging and dragged gear are incompatible with regenerative outcomes.
- Single use plastics and persistent materials shift ecological risk and fail the regenerative standard.
- Habitat recovery must be allowed, not suppressed.
- Operational restraint is a feature, not a flaw.
