Rapid reproductive analysis and length–weight relation of blacktail snapper, Lutjanus fulvus (Actinopterygii: Perciformes: Lutjanidae), from a remote village in Papua New Guinea
Longenecker,K. | Langston,R. | Bolick,H. | Kondio,U.
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.
