<p>The mangrove red snapper <i>Lutjanus argentimaculatus</i> (Forsskål, 1775) has a complex life history, utilizing both inshore and offshore habitats at various life stages. Batch spawning occurs in the marine environment, mainly during summer, with adult females releasing up to 4 million ova during a single spawning season. Preflexion larval development occurs at sea with an onshore movement commencing at ~ 20 mm body length or 1 month in age. Occupation of coastal and/or riverine nursery areas is a dominant feature of the life cycle of this species for at least the first 2 years. Although individuals can remain in rivers and estuaries for up to 11 years, most fish recruit to marine offshore areas from about 2 years onwards when growth rates slow down to 25–50 mm per annum. Males tend to mature before females, with most males fully mature by 7 + years and females by 8 + years. This is a long-lived species, with a maximum age in excess of 40 years. <i>Lutjanus argentimaculatus</i> is an ambush predator, preying mainly on sesarmid crabs, penaeid prawns, small fish, and shrimps in coastal ecosystems as juveniles and crabs and fishes in the marine environment as adults. This species appears physiologically and ecologically well adapted to cope with climate change. However, in terms of global change drivers, fish overexploitation and coastal habitat degradation are the two biggest threats to <i>L. argentimaculatus</i> populations. Currently, the IUCN Red List categorizes this species as being of Least Concern (LC), but this needs to be reassessed.</p>

摘要

The mangrove red snapper Lutjanus argentimaculatus (Forsskål, 1775) has a complex life history, utilizing both inshore and offshore habitats at various life stages. Batch spawning occurs in the marine environment, mainly during summer, with adult females releasing up to 4 million ova during a single spawning season. Preflexion larval development occurs at sea with an onshore movement commencing at ~ 20 mm body length or 1 month in age. Occupation of coastal and/or riverine nursery areas is a dominant feature of the life cycle of this species for at least the first 2 years. Although individuals can remain in rivers and estuaries for up to 11 years, most fish recruit to marine offshore areas from about 2 years onwards when growth rates slow down to 25–50 mm per annum. Males tend to mature before females, with most males fully mature by 7 + years and females by 8 + years. This is a long-lived species, with a maximum age in excess of 40 years. Lutjanus argentimaculatus is an ambush predator, preying mainly on sesarmid crabs, penaeid prawns, small fish, and shrimps in coastal ecosystems as juveniles and crabs and fishes in the marine environment as adults. This species appears physiologically and ecologically well adapted to cope with climate change. However, in terms of global change drivers, fish overexploitation and coastal habitat degradation are the two biggest threats to L. argentimaculatus populations. Currently, the IUCN Red List categorizes this species as being of Least Concern (LC), but this needs to be reassessed.
