The unique ambush hunting behavior, nocturnal activity pattern and slow growth rate of the O. marmorata have become a research hotspot in ecology and physiology. After moving to a new habitat, the marble goby is confronted with various challenges, such as the survival of the young fish during the breeding process. The market demand for marble goby in the fishery industry and its huge breeding potential and economic value. This study analyzed some research achievements in aspects such as the origin, geographical diffusion and ecological adaptation mechanism of marble goby. The impact of human activities on the distribution of marble goby highlights the necessity of achieving sustainable management between economic benefits and biodiversity conservation. Future research will focus on the integration of genomics and ecology to better breed, protect and manage marble goby. Keywords Oxyeleotris marmorata; Geographic distribution; Ecological adaptation; Molecular evidence; Fisheries management 1 Introduction Oxyeleotris marmorata is a freshwater fish distributed in Southeast Asia, mainly in Sumatra, Kalimantan, Papua and the Southeast Asian mainland, etc. (Syaifudin et al., 2021). The characteristics of O. marmorata such as ambush hunting, slow growth and nocturnal activity make it one of the important topics in ecological and physiological research (Lim et al., 2020). Furthermore, O. marmorata have also been introduced to other habitats, such as Indonesia, and have successfully settled there since 1927 (Lestari et al., 2019). The research on O. marmorata mainly focuses on aspects such as population genetics, physiological adaptation and reproductive biology, and has a profound understanding of the ecological role and evolutionary history of O. marmorata (Liu et al., 2020). Due to the large market demand and great breeding potential of O. marmorata, it has significant economic value in the fishery. However, some problems such as feed and the survival rate of juvenile fish may be encountered during the breeding process (Tan and Lam, 1973). The excellent nitrogen retention capacity and metabolic adaptability of the marble goby make it an ideal candidate species for sustainable farming (Tng et al., 2008). As a top predator, the O. marmorata poses a threat to the diversity of local fish when introduced into non-native environments. Therefore, breeders need to manage and control the population carefully. From an ecological perspective, the dietary preferences, diurnal metabolic patterns and reproductive strategies of O. marmorata enable them to survive in different freshwater habitats and have an impact on the ecosystem structure (Lim et al., 2017). This study will explore the origin, geographical diffusion and ecological adaptation of, analyze the local and invasive distribution of O. marmorata, and reveal its distribution characteristics and population structure through genetic and phylogenetic research. This study will analyze the main ecological adaptations and physiological characteristics of this species, including foraging behavior, metabolic mechanisms and reproductive biology. This study will also explore the significance of the latest research findings for fishery management, aquaculture and freshwater ecosystem protection, which can provide a comprehensive understanding of the key factors influencing the distribution, adaptation and ecological impact of Pelteobagrus fulvidraco.
