Yes, fish and shrimp can overheat as water temperatures rise due to climate change, or even just because of summer’s normal temperatures. Extreme heat can stress them, affect their metabolism (how fast they grow, eat, breathe, and live), and even lead to death (unfortunately), as they depend on specific temperature ranges for survival. So, climate change’s rising temperatures pose a significant threat to aquatic life. 🌡️🐟🦐😢

Following on from Amina’s excellent answer, if fish or crustaceans have damaged gills because of disease, pollutants or exposure to tiny spiky or stinging marine organisms, they will not be able to breathe so well, particularly at warmer temperatures when there is less Oxygen in the water (warm water accepts less dissolved Oxygen than cold water).
It is also worth remembering that, unlike humans, dogs, cats, birds and dolphins, the temperature of fish and crustaceans is largely dependent on their surroundings as they do not really produce their own heat to stay at a constant temperature. If they want to increase or decrease their temperature they must move to warmer or colder water, stay in shade or sunlight, change their colour or use other means to keep themselves at their preferred temperature.
