Flying in a helicopter high above the coast of Greece, German photographer Bernhard Lang captures unusual networks of circular fish farms. The strange, ovoid enclosures appear like abstract geometric designs, hardly related to the thriving ecosystems of fish that lay just below the surface. Aquaculture is seen by many as a more efficient way to safely breed larger volumes of fish instead of harvesting wild populations, but concerns about the environmental impact near farming sites have raised a lot of questions.
“Greece’s aquaculture industry is important for the country,” Lang shares. “Especially [because of] the bad economic situation in Greece. Fish, mainly sea bass and sea bream is one of their biggest agricultural exports, next to olive oil.” That said, fish prices have fallen sharply in recent years, further threatening a burgeoning industry.
