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.
