What can increased temperatures in water bodies do to aquatic life?

Increased temperatures in water bodies can significantly hinder growth and oxygen availability for aquatic life. Warmer water holds less dissolved oxygen compared to cooler water, which is critical for the survival and growth of many aquatic organisms, including fish and invertebrates. The reduced oxygen levels can lead to stress in aquatic species, impairing their ability to grow, reproduce, and thrive. This is especially concerning for organisms that are fully dependent on specific temperature ranges and oxygen levels.

Additionally, higher temperatures can alter metabolic rates within species, further impacting growth and survival. For instance, fish may experience increased stress levels, leading to lower reproductive success and increased susceptibility to diseases. The overall decline in oxygen availability can create unfavorable conditions, potentially leading to decreased biodiversity in the affected ecosystems.
