Aquaculture is one of the fastest-growing food production area in the world, and according to a FAO report (The State of World Fisheries and Aquaculture 2012), farmed fish will exceed captured fish for human consumption by 2018. As overfishing reduce fish stock in the ocean, aquaculture has become even more important.   

When talking about a successful aquaculture model, cleanliness of the water is crucial, especially for some aquatic organisms of great economic value such as shrimp and crab. But keeping the water clear and healthy for fishes is not as easy as it sounds since it requires experience and a lot of effort. What’s more, intensive aquaculture is very common in Taiwan because of the extremely high population density, but controlling the water condition will be even more difficult in such situation.

Some of the fishermen may turn to technology like recirculating aquaculture system (RAS). However, the astonishing operating costs make it a castle in the air for most of the fishermen. To solve these problems, we decided to build an easy-to- use device which keep the water clean with efficiency and reliability.

Controlling the concentration of Nitrate（NO3-）is an essential part of our project. When there is limiting nitrate, unwanted algae will decrease and also avid to use antibiotics. With the device and app we develop, nitrate in the fish-pond will be transformed into harmless molecule and under monitor the condition of the water at once, making the traditional aquaculture safer, easier and more eco-friendly.
