Editing relevant genes can influence the relative proportions of various fatty acids in the fat tissue. This is crucial for improving the quality and health properties of crucian carp fat, as fatty acid composition directly affects its edible value. Regulating fat content through gene editing may also bring a range of health benefits. Reducing fat content can lower the risk of obesity-related diseases in crucian carp, such as fatty liver and diabetes. This contributes to the production of healthier crucian carp products. This is essential for consumer health and helps meet the growing demand in modern society for food that is both healthy and safe. Therefore, gene editing in crucian carp embryos not only holds economic significance for the aquaculture industry but also has a positive impact on the food industry and consumer health. These research findings suggest that gene editing technology has the potential for widespread application in improving crucian carp fat content. 5.2 Correlation analysis between gene editing targets and fat content To gain a deeper understanding of the impact of crucian carp embryos gene editing on fat content, researchers are conducting correlation analyses to explore the relationship between editing targets and fat content. Editing key genes involved in fat metabolism has become a focus. Researchers typically choose to edit genes closely associated with fat metabolism, such as fatty acid synthase, fatty acid oxidase, and hormone receptors. By editing these genes, targeted interventions can be made in the fat metabolism process, thereby influencing changes in fat content. This precise editing strategy provides a powerful tool for regulating crucian carp fat content. The timing and extent of editing are crucial for regulating fat content. Researchers need to determine the most suitable developmental stage for editing and the degree of editing required to achieve the desired regulation of fat content. Research in this area helps identify the most effective editing strategies. Gene editing not only focuses on fat content but also aims to enhance fat quality, ensuring the controllability and stability of fat content. By editing, fatty acid composition can be controlled to make it more suitable for consumption and processing. This is competitive in the market for producing high-quality crucian carp products that are both market competitive and beneficial to health, such as those with suitable fat content and a healthy fatty acid composition. Improving fat quality makes products more in line with the needs of different markets and consumers. By delving into the impact of gene editing in crucian carp embryos on fat content, a better understanding can be gained of how to precisely regulate this important quality characteristic to meet the needs of different markets and consumers. This provides new opportunities for the aquaculture industry and encourages researchers to better utilize gene editing technology to enhance the quality and sustainability of crucian carp, realizing broader application prospects. 6 Influencing Factors and Challenges 6.1 The influencing factors gene editing efficiency and stability In the research of gene editing in crucian carp embryos, one of the crucial determining factors is the choice of editing tools, along with editing efficiency and stability. These factors directly impact the success of the editing process. The selection of suitable gene editing tools is essential for achieving efficient and stable edits. Currently, the CRISPR-Cas9 system is one of the most widely used tools, but researchers need to optimize the system to adapt to the specific biological characteristics of crucian carp. Only through thorough optimization can we ensure that the editing tools achieve maximum effectiveness in crucian carp. The choice of editing targets also plays a significant role in editing efficiency. Different genes may exhibit varying editability, with some being more amenable to editing than others. Therefore, before embarking on gene editing in crucian carp embryos, it is crucial to carefully select target genes and consider their biological functions. This selection process should undergo thorough research and scrutiny to ensure that the chosen editing targets are wise and scientifically sound choices.
