Which outcome occurs when blood flow to a fish's swim bladder is redirected during rapid ascent?

💡 Explanation

When blood flow is redirected, a fish cannot equalize pressure within its swim bladder causing Boyle's Law effect, due to rapid ascent as external water pressure decreases the volume inside the swim bladder increases past its elastic capacity leading to mechanical failure. Therefore swim bladder rupture results, rather than buoyancy rate or osmotic issues which require different mechanism.
