Abstract
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.
摘要
变态后（银色）的美洲鳗鲡鳔中的气体沉积速率比变态前（黄色）个体的约高五倍。这扩展了银色鳗鱼能够维持鳔体积的最大深度，并为它们向马尾藻海的产卵洄游做好准备。
