摘要：
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 L-50 at 13.5 cm FL and female L-50 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.
