Fish can adapt to ocean acidification through various mechanisms. One way is by regulating their acid-base balance through ion transport processes in their gills and kidneys. Some species can also adjust their behavior, such as seeking out areas with more favorable pH levels. Additionally, fish may undergo evolutionary changes over time to adapt to changing ocean conditions. It is essential for fish populations to have genetic diversity to increase the likelihood of some individuals having traits that are better suited to acidic conditions.
