Fish that make their way into the Dead Sea die quickly because the Dead Sea's extreme salinity is inhospitable to them. Its salt concentration is about 9.6 times saltier than typical ocean water, which causes salt to quickly disrupt the fish's internal balance. Freshwater fish, for instance, cannot regulate this excess salt, leading to dehydration and death. Even saltwater fish cannot survive due to the extraordinary salinity level. Only certain bacteria and microorganisms can live in the Dead Sea, while fish and aquatic plants cannot survive in its waters.
In summary, any fish entering the Dead Sea will die rapidly as they are unable to survive the lake's highly saline conditions.
