In intensive aquaculture, fish are confined in tightly packed sea cages and net pens. These intensive operations, also called fish farms, contribute to disease transmission, impact surrounding ecosystems, and place additional pressure on wild marine life. They also cause enormous pain and suffering for the individuals inside the nets.
With global demand for fish rising, fish farming continues to expand, introducing complex environmental challenges across our oceans.
We reveal these realities to provide context for what is happening beneath the surface, where scale, suffering, and consequences are often out of view.
Save this post to help bring these realities into focus and join us for a discussion in the comments: What actions can we take for our oceans today?

Nearly all the fish exhibited signs of disease or physical trauma, primarily on their fins and skin. Fish have highly sensitive pain receptors in their skin, suggesting such injuries may be extremely painful. Undisclosed, Finland, 2024. Rontti Varjola / We Animals
