Fish do not photosynthesis as this is the process of converting sunlight and carbon dioxide, into oxygen and energy. Fish use a process called ram ventilation to transfer the oxygen in water into their bloodstream.
Oil and natural gas.
the gas is may be another chemical that the fish can breath at the surface an can help to make the fish can breath at small air and big water.
When fish take in water, they extract dissolved oxygen through their gills, which is essential for their respiration. The gills filter out the oxygen from the water, allowing fish to breathe. Additionally, fish may also remove carbon dioxide and other waste products from their bloodstream as water passes over their gill filaments. Thus, the primary function of this process is to facilitate gas exchange for survival.
Fish do not respire substance in the gas phase, the compound that "is given out" is Carbon Dioxide (in solution).
