Abstract Description of striped trumpeter (
Latris lineata (Forster
in Bloch
and Schneider 1801)) eggs and larvae, previously described in summary only, is
provided
and illustrated from laboratory-reared material. Laboratory fertilised eggs are
round, 1.26-1.44 mm diameter, with a single, pigmented oil globule 0.27-0.29
mm diameter in an unsegmented yolk. Early-stage embryos are pigmented on trunk
and tail dorso-laterally, forming a dorsal and ventral pigment band in late-stage
embryos. Hatching occurs 7-8 days post-fertilisation in 12°C. Larvae are
2.8- 3.5 mm body length (BL) at hatching with a voluminous finfold, large yolk
sac with centrally-placed oil globule, distinct pigmentation pattern, and no
head spines. Flexion occurs from 5.6 to 8.7 mm BL. Fin formation commences from
6.6 mm BL in the sequence caudal, dorsal and anal (simultaneously), pectorals
and pelvics. Myomeres number 33-39. Larvae are pigmented predominantly on the
head, dorsal and ventral surfaces of trunk and tail, and gut ventrally, with
melanophores also on upper and lower jaws. Larvae survived to 45 days post-fertilisation,
11.9 mm BL, with complete fin-formation of the caudal fin only. Similarities
are noted between L. lineata larvae and aplodactylid, bovichtid, cheilodactylid,
chironemid, sillaginid, and tetragonurid larvae. A small number of lineata
larvae were also caught inshore and at shelf edge on the Tasmanian west coast
in late winter/early spring (September/ October).
