Firstly, the growth characteristics of Pterygoplichthys disjunctivus and its relationship with feed fat level were explored through literature review. Then, according to the experimental plan, the experiment was divided into two groups, one using high-fat feed and the other using low-fat feed. In the process of the experiment, it is necessary to regularly record the growth, weight and color of Pterygoplichthys disjunctivus, and conduct data statistics and analysis. Finally, based on the experimental results, the impact of feed fat level on the growth and color of Pterygoplichthys disjunctivus is summarized and analyzed, providing scientific basis and reference for the aquaculture of Pterygoplichthys disjunctivus.【Keywords】Pterygoplichthys disjunctivus; feed fat level; growth; color; influence
