Which outcome impairs buoyancy when gas bladder volume decreases?

💡 Explanation

Reduced swim bladder volume limits lift via hydrostatic adjustment, due to reduced gas volume; this decreases ascent rate because buoyancy decreases, therefore fish lift slows, rather than descending faster due to gravity overwhelming the smaller lift.
