gabions are partially flexible block structures are used by oyster farmers for several practical and ecological reasons. Here’s why they are popular:
1. Better Water Quality
Oysters filter water as they feed, and floating cages are kept at the water’s surface or just below it, where oxygen levels and plankton (their food source) are higher.
This improves oyster growth rates and survival.
2. Reduced Predation
Floating cages are elevated off the bottom, which helps protect oysters from bottom-dwelling predators like crabs, starfish, and certain fish.
3. Minimized Sediment and Fouling
Being above the sea floor reduces the buildup of mud, silt, and debris, which can smother oysters or interfere with their feeding.
4. Improved Growth and Shape
The movement of floating cages in the waves helps tumble the oysters naturally, encouraging them to grow in a more desirable, deep-cupped shape and discouraging clusters.
5. Ease of Access
Floating systems are easier to access and manage than bottom cages, allowing farmers to inspect, clean, and sort oysters more efficiently.
6. Flexibility and Scalability
Floating cages can be used in a wider variety of locations and are easier to expand or reposition as needed, compared to traditional bottom culture.
In summary, floating oyster cages enhance growth, quality, and farm management, making them a practical choice for modern oyster aquaculture.
