Abstract
An investigation of spontaneous bioluminescence as related to sonic-scattering layers was undertaken off Fuerteventura, in the Canary Islands. The apparatus used is described. A definite increase in the magnitude of luminescence at scattering-layer depths is demonstrated. It is shown that the amount of luminescence forward of, and in the net of an Isaacs-Kidd trawl, is very much greater than that either above or below it. A frequency is disclosed within a single flash, and it is hypothesized that this may be a specific property.
