What is/are the problem/s your design is addressing?

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.

What question/s is your design investigating?

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?

How does your design aim to positively impact the oyster farming community?

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

Research & Development

  1. What is it? What does it do?

A: It is a floating oyster farm.

  1. What are the questions this work is asking? What new knowledge are you creating?

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.

  1. How are you going to test your assumptions?

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

  1. How to maintain your device?

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

  1. What do you think are the strongest and the weakest points in your project now?

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

  1. What construction technique are you using?

A: Foldable technique and bamboo assembling construction.

User, community

  1. Who uses it? Can you draw a particular user? Can you describe to me that user, how they look, your assumption on their backgrounds, abilities, preferences, and what drives them?

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


  1. What are the benefits users can get from the device?

A: Reduction in duplication of effort.

  1. What problems does your design cause?

A: Diseconomy of construction materials and power.

  1. How do you operate and maintain this installation?

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.

  1. How do people get on board?

By boat.

  1. How much weight can you carry?

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

  1. How to maximum efficiency and convenience for the user

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

  1. Are there simpler ways to achieve the objective?

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

  1. Are there other possible use for clean seawater filtered by oysters?

A: Provide safer food for other marine animals.

  1. How long will it be in the water?

A: For a few months according to the estimation.

Health & Safety

  1. Is it stable? Safe? ship survivability?

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

  1. Is the device safe and environmental friendly to the ocean

A: Yes.

Materials, process, scale

  1. What is the scale and materials? Where and how is it built? Where do the materials come from? Where do the materials go after it’s used/broken?

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.

  1. How long does the project take to be complete: build, bring on site and board?

A: A week according to estimation.

  1. How to mass produce the device?

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

Energy, Waste

  1. Where does the installation get its energy from?

A: Solar panels and tidal energy.

  1. Is it sustainable and how?

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


  1. Is your installation amicable to all marine lives?

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

  1. How does it work? Especially the biology of it?

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

  1. Which other species will naturally be attracted to the oyster reef there, such as crabs, fish, mussels, algae and other species?

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


  1. Where do you think this installation would be? Choose a very specific site in Hong Kong waters. Why there? Tell me the characteristics of the place: water depth, tide, current, wave, closest port, fauna and flora, people and industries nearby.

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

  1. Will it be influenced by the weather condition?

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.

  1. Does your device perform differently when in different geographic environments(for instance, near shore, in shallow water, and in distant seawater)?

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


  1. Is it cost-effective?

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

  1. Is it possible to be mass-produced?

A: Yes.

  1. What is the product / outcome of this installation? Who benefits from it? What is the business model of this?

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.
