Which outcome reduces buoyancy control when a large physoclistous fish rapidly ascends to the surface?

💡 Explanation

When a physoclistous fish ascends rapidly, gas gland diffusion cannot equilibrate bladder volume rapidly, causing it to overexpand because pressure decreases, potentially rupturing the bladder. Therefore, swim bladder overexpansion damages happens, rather than increased blood O2, reduced fin effectiveness, which require different mechanisms.
