Abstract:	In the Lago do Rei, larval distribution showed a significant increase in density at 22 hr regardless of season or habitat, which suggests a diel vertical migration pattern. This could be only partly related to a metabolic efficiency resulting from prawns residing at cooler depths during the day. In shallow tropical waters, predation by visually dependent planktivores can be a more important factor. -from English summary
