在新玩法帕萨马科迪湾，利用肠道压力传感超声波发射器测定了5条美洲鳗（Anguilla rostrata）秋季的游泳深度。鳗鱼频繁地从水面下潜到水底，在某些地方下潜至少45米深，垂直速度达到76厘米/秒。 大约四分之一的时间花在表面附近;很少的时间花在底部附近或任何恒定的中间深度范围。
Pressure-sensing ultrasonic transmitters in the gut were used to determine the swimming depth of five American eels (Anguilla rostrata) in Passamaquoddy Bay, New Brunswick, in autumn. The eels made frequent dives from surface to bottom, in places diving at least 45 m deep, at vertical speeds to 76 cm/s. About one quarter of the time was spent near the surface; very little time was spent near the bottom or at any constant intermediate depth range.
