What happens if gills are damaged?
Most fish breathe when water moves across their gills. But if the gills are damaged or water cannot move across them, the fish can suffocate. They don’t technically drown, because they don’t inhale the water, but they do die from a lack of oxygen.

How do you know if your fish gills are inflamed?
Symptoms. Because the gills are primarily affected, fish suffering from bacterial gill disease will have respiratory problems, with visibly rapid or labored breathing and swimming close to the surface of the water as if trying to get air.

What is a gill net and how does it work?
If you don’t know what a gill net is, it’s a floating wall of monofilament-line, designed to snare fish by their gills as they try to swim through the net mesh. In most cases, nets are left out overnight and are pulled up in the morning, and anything that has become entangled in them is pulled into the boat.
Should gill nets be banned?
Banning gill nets is the first step but when you look at how many fish they take, there’s an even bigger problem. Stats from the most recent year of data available (2017) show that North Carolina harvested more redfish, speckled trout, and flounder than any other state on the list.
