Sea-based fish farming systems using net pens are hard on the environment and fish. A closed cage can improve fish welfare, but seawater must be continuously circulated through the cage. However, waves can cause the water to slosh inside the cage, creating violent motions and endangering the cage and fish. A study using a scale-model containment system is reported in Physics of Fluids and shows why violent sloshing motions arise and how to minimize them.
