In the study of Sempor Reservoir, it was found that the fishery development speed in the central region was five times that of the export area, and fishery activities were the main cause of death of snailfish in highly developed areas (Lestari et al., 2019). Overfishing may lead to a reduction in the population size of O. marmorata, alter their growth age and body structure, affect genetic diversity, and influence their ability to adapt to environmental changes. The construction of human habitats, such as reservoirs and other water resource management facilities, can promote the expansion of new growth areas for O. marmorata and may also lead to O. marmorata becoming invasive species, thereby threatening local biodiversity. On the contrary, overexploitation and habitat destruction may also limit the distribution range of O. marmorata, reduce the richness of O. marmorata species, and highlight the complex interrelationship between human activities and species distribution. 7.3 Suggestions for the maintenance and management strategies of O. marmorata The cultivation, protection and effective reproduction of O. marmorata require finding a balanced approach. Address the risks of overdevelopment and assess the possible ecological impacts of introducing new habitats. Population control measures were taken and targeted fishing was carried out within a specific body length range (13.38-17.30 cm), which can help manage the population size and reduce the negative impact on the local fish community (Lestari et al., 2019). Keep the catch rate below the sustainable threshold (such as E≤0.5) to prevent overfishing and ensure the long-term reproduction of O. marmorata. In terms of fish conservation, protecting and restoring habitats is also very important for maintaining healthy populations. Monitoring water quality, regulating pollutant emissions and protecting natural habitats can effectively mitigate the adverse effects brought about by human activities. Combining the enhancement of public awareness with the participation of stakeholders can sustainably manage and protect the ecosystem and habitat of O. marmorata. 8 Future Research Directions 8.1 Further explore the application of genomics and molecular biology in the research of marble goby The latest advancements in genomics and molecular biology offer significant opportunities for a deeper understanding of marble goby. With the help of high-throughput sequencing technology and genome assembly, genetic diversity can be revealed, adaptive genes identified, and the evolutionary relationships within and outside the population can be revealed. These technical methods, similar to the research applications on other species, can detect gene regions affected by selection pressure and help identify genetic markers related to key physiological and ecological characteristics, which is crucial for the implementation of basic research and breeding programs (Gao et al., 2018). In future research, researchers can combine genomic data with ecological and physiological studies to explore the molecular mechanisms by which bamboo snappers adapt to different environments. The development of more genomic resources, such as annotated reference genomes and transcriptome data, can provide strong support for the study of gene expression, epigenetic regulation and protein function. These tools are also helpful for identifying candidate genes related to stress resistance, growth and reproduction, and are very important in molecular-assisted selection and conserved genetics (Kelley et al., 2016). 8.2 The relationship between ecological adaptation and environmental changes The adaptation of O. marmorata to changes in their growth environment can be used to predict their responses to habitat changes and climate changes. In some studies of snappers, ecological adaptation is usually the result of the combined effect of genetic diversity and phenotypic plasticity, which enables snappers to survive in a constantly changing environment. Genomic studies can explain the genetic basis of local adaptation. Combined with
