This paper has investigated the significant sex ratio changes shown by lampreys under specific environmental conditions, and has analysed the impacts of lampreys on the ecosystem. It has explored the effects of changes in its sex ratio on food resource use, food chain structure, reproduction rate, and habitat use based on an ecosystem model of logistic modelling, thus revealing the major adjustments in ecological balance and impacts on system stability that may result from changes in sex ratio. This paper has further applied the TOPSIS model to parasitoids to analyse the potential advantages that changes in sex ratios bring to other species within the ecosystem, including the effects on food webs, ecological niches, parasitism processes and system health. The results of this study suggest that changes in the sex ratio of lampreys can provide advantages to specific species (especially parasitic species) through a variety of mechanisms.
