Egg: This and the previous species (LIIB7) were separated from other eggs with yellow pigment on the yolk, by the paleness of the yellow (almost white) and the tendency for the pigment spots to be concentrated on the edge of the yolk (A). Both the embryo and oil globule are dotted with white-yellow and stringy black pigment spots (A). The oil globule is clear. Pectoral buds can be seen on the late embryo, within the egg. The egg is sometimes slightly oval. The yolk is misty and has a goose-pimpled surface. Incubation is 45-48 hours.

Larva: The larva is difficult to separate from LIIB7, until reared to the pigmented-eye stage, when the lack of spots on the pectorals, was used to separate this species.  B: 1 day, C: 2 days, D: 3 days, E: 4 days (25°C).

No larval DNA barcoding sequences are currently available, to identify this egg.

This was an uncommon egg off Park Rynie, with spawning showing a peak in the winter/spring period (blue graph). It was only seen once in the DHM samples, in October. The capture of eggs at Park Rynie, through the 25 years of sampling, has been sporadic, with batches of good years followed by batches of lean years (white graph). The Park Rynie linked samples showed more of these eggs inshore (74%), indicating spawning close inshore, around the 15m contour (but numbers are low). See Section 7.3 and Table 1 of the Introductory Notes, for more information on the linked samples
