This is an aerial photograph of a series of fish farms that I captured from a helicopter above the coast of Greece in June 2017. I was captivated by how surreal the arrangements of nets and cages looked from the air. To me they appeared like abstract geometric designs.

In actuality, of course, while intensive and sustainable mass animal farming on the sea might be one way to help feed the growing world population, there are issues in fish farming which make it highly controversial. Feeds, diseases and parasites, and the use of antibiotic drugs are all problems that contradict the aesthetic beauty.
