We ended up presenting our project for the locals on the island. When we told them that the fish had disappeared they quickly ensured us that they for sure would be able to find it – because many of the people on Ærø knows each other. From this knowlegde it seems that our data collecting fish have potentiel to make a great map all across the island. But we would have to redesign and reprogram it a bit. We have evaluated that it would be a better idea to have a almost constant collect gps-data and put an independent server inside to keep a good signal.
