Gas bladders make up an average of 5 percent of body volume in marine fish and 7 percent of body volume (on average) in freshwater fish. What is the reason for this difference? freshwater fish have a larger average body size than salt water fish it is more difficult to produce lift swimming in freshwater than swimming in saltwater freshwater fish need to have a lower overall body density in order to remain neutrally boyant freshwater fish need to have a higher overall body density in order to remain neutrally boyant
