What is a major impact of climate change for fish species?

Answer 1

A major impact of climate change on fish species is the alteration of their habitats and distribution patterns. Rising temperatures, changing ocean currents, reduced oxygen levels, and other climate-related factors can lead to significant changes in the availability and quality of habitats for fish. This often results in shifts in their geographical range and abundance. Some fish species may need to migrate to colder waters or deeper depths to find suitable conditions, while others may struggle to adapt to these changes, leading to declines in population sizes. Additionally, climate change can also affect the availability of food sources for fish, causing disruptions in their natural feeding patterns and ultimately impacting their overall survival and reproductive success.
