Aquarech App is designed to help aquaculture farmers monitor these fish cages and connect them with feed salesmen who can supply the best feed for their farms. There are three parts to the system- an app, a thermometer for the fish ponds or cages, and a website for the feed producer to process orders. The app is designed for farmers to be able to input relevant data on a daily basis about the conditions of their fish ponds, relative fish mortality rates, and profit gains. The farmers can then track these indicators and receive personalized recommendations for the feeding amounts and schedule of the fish. The digital thermometer connects by Sigfox technology to the app to give feed recommendations based on water temperature and the feed fulfillment website helps the fish feed factory fulfill these orders.
