Abstract : A vertical migration tube (VMT) was designed and constructed as an instrument to be used with a photomultiplier light detector to make in situ mesopelagic studies of deep scattering layer vertical migration organisms. Laboratory test equipment and laboratory methods were developed to permit quantitative measurements of euphausiid bioluminescent output. Laboratory tests of Euphausia pacifica indicated a greater bioluminescent response to a standard flash stimulus during midnight tests as opposed to noon tests. Laboratory tests of bioluminescent activity during periods of moulting indicated greater than average response to a photoflash stimulus just prior to moulting and less than average response just after moulting.
