Abstract: Mangrove Red Snapper has been a valuable aquaculture fish in Vietnam, however, its aquaculture mostly depends on fingerlings collected from the wild. There is no ecological study conducted for this species in Vietnam, although its resource is seriously threatened by increased fishing and habitat depression. In this study, we examined the recruitment and habitat ecology of juveniles. We found that there was only one main period of the recruitment occurring in July to August, with a large number of <3cm fish caught. Most juveniles were associated with rocky habitats in brackish water areas that comprised a wide range of natural food prey, especially dominance of shrimps. We also found that use of fishing gears was related to movement of juvenile fish during the recruitment. Here, we have shown important information on ecological aspects of juvenile Mangrove Red Snapper in central Vietnam that would be useful for next studies tending to maintain wild fish resource and support aquaculture as well.
