Abstract
During a fish resource survey of Jiquilisco Bay, El Salvador, from September 1975 to November 1976, the three dominant commercially important families were the Ariidae, Gerreidae and Sciaenidae. For combined data, peak capture abundance occurred during the rain y season (May to September) and consisted mainly of pre-adult fishes. Gonadal inspection and occurrence of pre-adults indicated prolonged and variable spawning seasons for most species; only Galeichthys jordani (Ariidae), showed a restricted spawning season with young-of-year peak abundance during the mid-rainy season. The 11 sciaenid species probably do not spawn in this coastal lagoon but use it as a nursery area.References
