The Vietnamese Mekong Delta boasts a rich diversity of fish species, including over 300 types in its freshwater, brackish, and saltwater environments. The Mekong River plays a crucial role in supporting these fish populations, particularly the Butidae, Gobiidae and Eleotridae fish families, which have economic significance. Although research has been conducted on these fish species in recent years, it has been fragmented, making it challenging to assess and conserve these resources effectively. This monograph addresses this issue, offering a comprehensive perspective on the fish family in this region. The monograph is the culmination of a decade of research, featuring in-depth investigations, covering genetic characteristics, morphology, reproduction, feeding habits, and population dynamics. The goal is to provide a holistic understanding of these species and their ecosystems, aiding their conservation. The research contributes to the broader sense of aquatic ecosystems and the intricacies of fish survival in this region.
