Dynamic Oyster Farming System

生蚝动态养殖系统

Since the accumulation of microorganisms can contribute to meshes being blocked and the growth of oysters being restricted, biofouling poses severe challenges to oyster farming. But the control strategies such as manual removal and pressure washing are both labor and capital-intensive.

Could we create a simple system to minimize the effects of biofouling?

Is there a more efficient way for the oyster farming process to save manpower and resources?

"Dynamic Oyster farming system" is investigating a more operable way to control biofouling while creating a convenient oyster farming system.

A: It is a floating oyster farm.

A: This work is asking for the method to control biofouling. The project is creating a way to rotate the oyster bag and control its floating condition in a simple and convenient way.

A: Test by making models with exact material and installations.

A: Use proper materials and construction methods. Regular check and renewal of components

A: The aim and concept are worth researching, but the technique still needs to be tested and simplified.

A: Foldable technique and bamboo assembling construction.

A: The oyster farmers. I think they prefer to build something simple. Questions: Do you rotate the oysters? The frequency? The influence for production?

A: Reduction in duplication of effort.

A: Diseconomy of construction materials and power.

A: Operate the floating installation by remote control of the buoyancy of the airbags. Regularly check the state of the structure and equipment or repair to maintain.

By boat.

A: 3-4 people besides the live load and gravity of structures and oysters.

A: Long-range control of the devices and electronic recording of the state of oyster growing.

A: The use of natural resources instead of electricity, such as tidal power and the change of temperature, need to be further explored.

A: Provide safer food for other marine animals.

A: For a few months according to the estimation.

A: Additional strengthening for the structure is needed considering about the extreme weather.

A: Yes.

A: The prototype can be 5*5 meters square made from bamboo, which comes from local areas. It is built on-site together with metal joints. The materials can be recycled after they are used or broken.

A: A week according to estimation.

A: Design with components that are widely used, turn the concept into digital models and prototypes, further research on the cost and marketing.

A: Solar panels and tidal energy.

A: Being sustainable by using recyclable materials and renewable energy sources.

A: Yes, the installation causes no harm to the environment and animals nearby.

A: Control biofouling by adjusting the state of oyster bags.

A: The rock-like reefs can provide habitat for other marine animals and plants, such as forage fish, invertebrates, and other shellfish.

A: Sea areas near the oyster farms, such as the Deep Bay.

A: Stability of the structure may be influenced by extreme weather, but the solar panels can store energy for the devices to keep the oyster growing system.

A: The device is of universal relevance, but the growth condition of oysters can be affected by different geographic environments.

A: Yes, materials for the design are not costly, at the same time, an increase in the growth rate will lead to more income.

A: Yes.

A: The product will contribute to a more efficient farming process, from which the oyster farmers and companies will benefit the most. The product can be self-made once the data has been tested.
