BUBBLE-NET : system to catch fish and the respective method of use
Fishing is a socio-economic activity of great relevance worldwide. However the environmental sustainability of the fishing gears is far from being effective. It is necessary to find more selective types of fishing to ensure sustainable catches of target species and also to protect other organisms ac...
