Gas deposition rates in the swim bladders of postmetamorphic (silver) Anguilla rostrata eels are about five times greater than those of premetamorphic (yellow) individuals. This extends the maximum depth at which silver eels can maintain swim bladder volume and prepares them for their spawning migration to the Sargasso Sea.
