In fish without a tube connecting the gastrointestinal tract to the gas bladder, how is the gas bladder filled?" Physoclistous fish release CO2 into into their gas bladders instead of excreting it from their gills. O2 is released from a capillary bed into the gas gland when the blood is acidified. CO2 is produced through aerobic metabolism by special cells in the gas gland. "O2, CO2, and N2 bubble out of the blood into the gas gland as fish ascend toward the surface. "
