Big waves costly for fish

New research shows fish may spend more energy under climate change. Big waves are energetically costly for fish, and with changing climates big waves are expected to become more frequent and more intense.

Using a water chamber, scientists monitored how fish dealt with changing conditions and how much energy was consumed when swimming in waves. Results showed it is much more energetically demanding for fish to deal with fluctuations in wave speed and water height.

Though some fish showed signs of better dealing with waves than others, suggesting there is hope that fish will be able to adapt their swimming behaviour to changing environments.
