This study analyzed the genome structure of largemouth bass and identified key genes related to growth and environmental adaptation. It further analyzed the roles of these genes in regulating growth and adapting to environmental changes, and explored the growth regulation pathways, hormonal control, and cellular and molecular processes of largemouth bass to understand its developmental mechanisms. Advances in genome sequencing technologies, transcriptomics, proteomics, and the application of bioinformatics tools help to more accurately analyze the genome and developmental data of largemouth bass. This research aims to reveal the genomic and developmental mechanisms of largemouth bass, deepen the understanding of its molecular basis for growth regulation and environmental adaptation, and hopes to further promote the research and development of largemouth bass, contributing new knowledge and strategies for aquaculture and ecological protection. Keywords Micropterus salmoides; Genome structure; Developmental mechanisms; Environmental adaptation; Inheritance 1 Introduction Largemouth bass (Micropterus salmoides) is a prominent freshwater fish species widely distributed across North America. Known for its significant role in recreational fishing and aquaculture, the largemouth bass has been extensively studied for its ecological and economic importance. This species exhibits remarkable adaptability to various environmental conditions, making it an ideal model for studying the genomic and developmental mechanisms underlying growth and environmental adaptation (Chen et al., 2022; Cui et al., 2023). Understanding the growth and environmental adaptation mechanisms in largemouth bass is crucial for several reasons. Firstly, environmental changes, such as hypoxic stress, can significantly impact the physiological and molecular responses in largemouth bass, affecting their survival and growth rates. For instance, research has shown that hypoxic conditions lead to differential expression of microRNAs in the liver, which in turn regulate key signaling pathways involved in stress responses (Sun et al., 2020). Additionally, environmental chemicals can disrupt endocrine functions, influencing reproductive development and overall fitness. Studies have identified specific gene clusters affected during ovarian development, highlighting the impact of environmental disruptors on gene expression and physiological endpoints (Basili et al., 2018). These insights are vital for developing strategies to mitigate the adverse effects of environmental stressors on largemouth bass populations. This study provides a comprehensive overview of the genomic and developmental mechanisms underlying the growth and environmental adaptation of largemouth bass. By elucidating the molecular and genetic basis of growth regulation in largemouth bass, it explores physiological and genomic responses to environmental stressors such as hypoxia and endocrine disruptors. It identifies potential pathways and gene networks involved in the adaptation process, thereby contributing to the formulation of effective conservation and management strategies for largemouth bass populations. By integrating recent research findings, this study will offer valuable insights into the complex interactions between genetic, developmental, and environmental factors in largemouth bass, ultimately enhancing our understanding of their adaptive capacity and providing references for future research directions.
