Egg: Green/yellow pigment covers the embryo, with less on the head (A & A1).  A few yellow pigment spots are seen on the oil globule. Black pigment follows the same pattern. The yolk is lightly segmented, mostly on the edges. The oil globule is light amber. Incubation time is about 35 hours (21°C). Eggs are sometimes found fresh, suggesting early morning spawning..

Larva: The early larva has a distinctive, green/brown to yellow/brown pigment pattern (B & C), reminiscent of mullet , but mullet have a much larger oil globule and unsegmented yolk. At 3 days prominent pigment patches have developed in the upper finfold (D), as occurs in the mullet. B: 1 day, C: 2 days, D: 3 days, E: 4 days (23°C).

This egg was not successfully reared. Six larvae hatched from this egg, have been barcoded, and matched 2 adults collected locally (BOLD).

These eggs were found most of the year at Park Rynie, with no clear trend (blue graph). They were uncommon with only about 110 collected in the 25 years of sampling. They were also never found in numbers, with a maximum of 10 in a single sample. They were not seen in the DHM samples. The annual trends graph, showed a brief increase in 1993/94, and a more stable presence n the second half of the study (white graph). In the Park Rynie linked samples, this egg showed a slight offshore majority (60%), indicating another species that is spawning inshore of the indicator species Argyrosomus japonicus. See Section 7.3 and Table 1 of the Introductory Notes, for more information on the linked samples.
