利用弹出式卫星发射标签（PSAT）研究了雌性安圭拉（Anguilla dieffenbachieels）的海洋产卵迁移。2006年5月发布的3条鳗鱼的游泳深度和经验温度数据与水温数据以及月球周期和区域水文学重新进行了研究，因为最初的研究没有考虑这些方面。Eel 2和Eel 3最初在600米以上经历了较低的水温，这表明它们在副热带辐合锋以南的时间比Eel 1长。 它们经历的夜间最小深度与月球周期呈线性关系，因为它们在新月期间比满月期间游得浅。鳗鱼在很宽的深度范围内经历了狭窄的深昼温度范围，而在温度变化更大的地方经历了狭窄的浅夜深度范围，这表明有几个不同的因素决定了它们的昼夜深度范围。
The oceanic spawning migration of femaleAnguilla dieffenbachiieels was previously studied using pop-up satellite transmitting tags (PSAT). The swimming depths and experienced-temperature data of 3 eels released in May 2006 were re-examined in relation to water temperature data, and also lunar cycle and regional hydrography as these latter aspects were not considered in the original study. Eel 2 and Eel 3 initially experienced lower water temperature above 600 m, suggesting they remained south of the subtropical-convergence front longer than Eel 1. Their experienced nighttime minimum depths showed linear relationships with the lunar cycle, because they swam shallower during new moon than during full moon. The eels experienced narrow deep-day temperature ranges at a wide range of depths compared to experiencing narrow shallow-night depth ranges where temperatures varied more widely, indicating that several different factors determine their day and night depth ranges.
