We present length–weight relations (LWR) and use rapid, low-cost histological methods to describe the reproductive biology of the red-bellied fusilier, Caesio cuning (Bloch, 1791), and the longfin emperor, Lethrinus erythropterus Valenciennes, 1830, based on 137 and 139 specimens, respectively, collected from a remote area in Papua New Guinea. The LWR for C. cuning is W = 0.0208FL3.0322. We estimate male L50 at 12.6 cm FL and female L50 at 15.3 cm FL. Overall sex ratio of mature individuals is not significantly different from 1 : 1; however, sex-ratio does vary with length. Females dominate size-classes from 17 through 20 cm and males are more abundant in smaller and larger size classes. The species is a batch-spawning gonochore. Batch fecundity is an exponential function of length BF = 0.1163FL4.2796. The LWR for L. erythropterus is W = 0.0145FL3.0976 for all specimens, but the length–weight relation differs between sexes. We estimate minimum size-at-maturity for males at 19.2 cm FL, and female L50 at 20.4 cm FL. Overall sex ratio of mature individuals is not significantly different from 1 : 1; however sex-ratio does vary with length. Males dominate size classes > 21 cm. The species is a batch-spawning, protogynous hermaphrodite.

nr 1

We present a length–weight relation and use rapid, low-cost histological methods to describe the reproductive biology of the blacktail snapper, Lutjanus fulvus (Forster, 1801), based on 124 specimens collected from a remote area in Papua New Guinea [W = 0.0134(FL)3.100]. We estimate male L50 at 13.5 cm FL and female L50 at 18.8 cm FL. Sex ratio is not significantly different from 1 : 1. The species is a gonochore. Mature females from 17.8 to 21.7 mm FL produce a mean 35 305 ± 29 141 eggs per spawning event.
