摘要

As with other representatives of the family Lethrinidae, L. nebulosus is a protogynous hermaphrodite, and sexual transformation from female to male occurs over a wide range of sizes (Young and Martin, 1982; Ebisawa, 1990). Lethrinids are considered to have long spawning seasons, running from spring to at least early fall, with spring and fall peaks. Spawning occurs after dark for most species in aggregations along the inner or outer edge of the fringing reef (Johannes, 1981). Lethrinus nebulosus is a large tropical species reaching 80.0 cm total length and 8.4 kg total weight (Randall, 1995) and is exploited throughout its range with a variety of gears (Fischer and Bianchi, 1984).
