FIGURE 2. Illustration of the method used for measuring the total length (TL) of Nothobranchius ocellatus specimens on a weekly basis. Specimens were placed in very shallow water in a clear, flat-bottomed glass dish (of a size suited to the size of the specimen) over graph paper and photographed from above. A straight line was then digitally drawn from the terminus of the upper jaw to the posterior margin of the caudal fin. The line was then rotated into alignment with the grid of the graph paper in order to closely approximate TL.
