Abstract

Sex ratio adjustment has a profound impact on the stability of the sea lamprey and its ecosystem, altering its reproduction and host relationship dynamics. To understand the complex relationship between sex ratio and population dynamics, and to reveal how changes in sex ratio affect reproduction, the present study was carried out to improve the model by establishing the basic Lotka-Volterra predator-prey model and improving the model by combining the characteristics of changes in sex ratio to obtain the results that the sex ratio of the sea lamprey is an important factor influencing the changes in the population size of the sea lamprey, and that the relationship between them shows significant differences in the different sex ratios. The relationship between the sex ratio and the population size of sea lampreys showed obvious differences, reflecting that the sex ratio not only determines the rate of increase and decrease of the population size but also indirectly affects the trend of the host population size.
