Sustainable fishing guarantees there will be populations of ocean and freshwater wildlife for the future. Aquatic environments are home to countless species of fish and invertebrates, most of which are consumed as food. For thousands of years people have fished to feed families and local communities and spearfishing has become the most sustainable fishing method. More spearos, than ever before, have now become ambassadors for the ocean, with our boy Robert John being one of them. "Being a great spearo doesn't mean you have to take as much as you can; in fact, it should mean the opposite".
