Boats for fishing, shipping or other activities are equipped with sophisticated measuring instruments. If we think about fishing for example, fishers have real time data to know exactly where is the fish, how much quantity. They can see and measure how old are the scampi and see if their breeding cycle has changed. They have the tools to measure how big is the impact however, data is not shared for commercial or competitive purpose, they will eventually sell it when they retired. This is a rich source of information to understand what’s going on. Can we think about an innovative way to involve fishers in the protection of oceans ? How should we use this data ?
