You can follow very interesting perspectives on Double crested cormorants…who
knew all of this…I certainly didn't

The chokepoint with booming numbers of DC Cormorants returning to historical
levels is that available nesting (and winter roosting) habitat is NOT doing the
same thing.
So DC Cormorants are displacing egrets and herons in rookeries and killing
large numbers of trees in rookeries and winter roosts with their droppings.
The day may come when we have to choose between 1. DC Cormorant culls or 2.
losing wading bird rookeries and seeing declining wading bird populations in
certain regions.
They have already faced it in Pennsylvania:

It’s an interesting situation with Double-crested Cormorants. I think those in
favor of controlling the population have a warped perspective in terms of
historical context, as cormorant numbers were greatly diminished for many years
by the lasting effects of DDT. What we are seeing now, is probably more normal
in terms of numbers. Interestingly, another species which has made a big
comeback, albeit many years later is the Bald Eagle. The comeback of Bald
Eagles has been not been good for Great Cormorants, but that species was not
nearly as abundant as Double-crested Cormorants. There is no doubt that
cormorants have a significant affect on fish stocks, but so does shrimping,
where there is a huge amount of by-catch that is beneficial to coastal seabirds
that have learned to follow the boats.

Thanks Dave for calling attention to this seabird fish consumption study,
apparently instigated by the fishing industry. Please remember, the net effect
of any wildlife on the ecosystem is much more than just their consumption. This
is NOT a dig at the study or those who carried it out.
Cormorants aint pretty, and they aint terribly popular among birders or
wildlife management agencies, not to mention with the general public and
fisheries people.
However, their role in the recycling of marine nutrients to coastal ecosystems
is major, they are one of the birds that roost above coastal wetlands and
return massive amounts of organic material to fishery nursing areas, making
them a real keystone species for productive coastal ecosystems and productive
fisheries in the long term. This benefits all our birds and other wildlife.
Birds such as Gannets and Gulls provide much less of this as they tend to roost
at sea. In contrast, practically zero of the marine nutrients taken by industry
trawlers are returned to fish nursery areas.
Through fish predation, Cormorants' active selection of fitness in fish
populations off, and near the coast is also a major feedback to ecosystem
productivity. This is different from people's fishing activity which doesn't
discriminate what kind of fish get in the net.
There's a real temptation to scapegoat common birds like cormorants for the
declining wildlife stocks, which are caused by people and their fossil-fueled
harvesting, that gives nothing back to the system. I ask birders to resist that.
