Adaptive responses and transgenerational plasticity of a submerged plant to benthivorous fish disturbance.

ABSTRACT: Submerged macrophytes play a key role in the restoration of shallow eutrophic lakes. However, in some subtropical lakes, benthivorous fishes dominate the fish assemblages and influence the growth of submerged plants. A comprehensive understanding of the direct and indirect effects of benthivorous fishes on submerged plants is important. We conducted mesocosm experiments to examine the effects of three densities of benthivorous fish, Misgurnus anguillicaudatus, on the water properties, the growth, asexual reproduction, and the germination of turions of Potamogeton crispus L. Our results showed that fish disturbance increased TN, TP, PO₄-P, NH₄-N, and NO₃-N of the water, raising the extinction coefficient K, Chl a, and the periphyton biom
