Deep water fish release mechanism

Deep Sea Angler Fish Lamp

Most of the fish we catch are hooked in the mouth. However, many times fish are caught with the hook buried in their stomach or gills. We call that being "gut hooked". Lots of people like to release their catch and sometimes they don't know how when the hook is buried so deep. I’ve watched people rip the hook out of a fish, insuring that it will not survive. I’ve seen people keep fish they ordinarily would have released had the fish not been hooked so deep. Conservation of the resource dictates we find a way to release as many of these fish in as healthy a state as possible.

Double Trouble

Some fish come up from deep water with two issues. First, they may be gut hooked, and second, because of the water depth, their air bladder may be distended as well. All fish have air bladders. They regulate the air in their bladder to remain neutral buoyant. The pressure difference from deep water makes their air bladder expand out their mouth if they come to the surface too quickly. These fish can still be released to fight again as you will see below. It takes special care and concern for the resource.

The Acid Test

All fish have a built in mechanism that will help them survive a hook. The larger the fish, the better the mechanism. Their body fluids contain a substance that can literally dissolve a hook within a matter of days. I have caught a number of large fish wherein an imprint of a hook can be seen inside their mouth cavity. The hook is gone – dissolved – but the outline is still there. I’ve cleaned fish and found the same thing in their stomach lining. Biologists I have interviewed in the past have provided me with data indicating the high acid content that dissolves the hook.

The Release Process

Given that these fish can dissolve the hooks relatively easily, the best method for releasing becomes obvious. I cut the line or leader off the hook as close to the eye as possible. Fish hooked in the gills are less likely to survive, but leaving the hook in place is far better than trying to remove it. Fisheries biologists confirm that the survival rate is extremely high if we simply leave the hook and cut the line.

Did you ever notice that fish hooked in the mouth area or in the stomach area never bleed? Bleeding fish will invariably be hooked in the gills, where their blood flows to gather oxygen from the water. The mouth area does not bleed. Fish are constantly being poked and stuck during their normal course of feeding. Larger fish, feeding on smaller fish are constantly being stuck in the mouth area with dorsal and anal fins – and painlessly, I might add. A hook is simply another fin to them.

Once the line is cut, I will make sure their air bladder has not been distended. If it has, a small puncture with a needle or the point of a hook will allow the pressure to equalize, and they can then swim back to the bottom.

WIPEOUT OF WORLD OCEAN ECOSYSTEMS
SUMMARY OF WHAT IS HAPPENING:
The estimated super high pressure release of oil from under the earth’s crust is between 80,000 to 100,000 barrels per day.
The flow of oil and toxic gases is bringing up with it… rocks and sand which causes the flow to create a sandblasting effect on
the remaining well head device currently somewhat restricting the flow, as well as the drilled hole itself.
As the well head becomes worn it enlarges the passageway allowing an ever-increasing flow
