Might see some larger fish but will likely see a decline in population.
Doesnt always work that way. A strong invasive species can choke out/displace the pike and trout as well as other species. There will be competition for food, as well as egg predation and I would bet they will feed on the young of the predators as well.
A water body can only support so much biomass. If the carp become even 30% of that biomass they have displaced 30% of the other species. Kind of easy way to put it but I think helps see the impact. Just used 30% as an example(probably will be much higher).
