How thick is 10 gauge welded wire mesh? is a common and important practice in oyster farming (aquaculture) for several key reasons:
1. Biofouling Control
Why it matters: Algae, barnacles, mussels, and other marine organisms can grow on the cages and oysters.
Flipping helps: Exposing the cages to air and sunlight during low tide or flipping them in water helps kill or remove these unwanted organisms.
2. Shell Hardening
Why it matters: Oysters with stronger shells are more resilient and marketable.
Flipping helps: The movement and tumbling of oysters within the cages during flipping causes minor abrasion, which encourages the oysters to grow thicker, stronger, and more uniformly shaped shells.
3. Growth Uniformity
Why it matters: Uniformly sized oysters are easier to harvest and sell.
Flipping helps: Movement redistributes the oysters, preventing overcrowding and allowing more even access to food and water flow.
4. Debris Removal
Why it matters: Sediment and waste can accumulate on or in the cages.
Flipping helps: Shaking and flipping dislodge this material, maintaining better water flow and reducing disease risk.
5. Predator and Pest Management
Why it matters: Predators like crabs or snails can infiltrate cages.
Flipping helps: Regular disturbance deters or exposes these threats.
In summary, flipping oyster cages helps maintain healthier, cleaner, and higher-quality oysters while also improving farming efficiency and reducing labor and maintenance costs over time.
