A fishes swim bladder is a sack shaped organ that is fed oxygen from the fishes gills as it breaths to give it just enough air-gas somewhere in its body, this is to stop it from sinking to the bottom of the ocean.

Air-gas it wants to expel,is let go through the gills as well.

The swim bladder is in the centre of its abdomen at the top of this part of them directly under its back bones-lateral line.

If it needs to rise in depth it expels some as the air-gas expanding as it rises, this enables it to keep the sack at exactly the same air-gas amount to remain floating and not sink at any depth.

What follows is the process of removing excess oxygen from a fishes swim bladder that has been brought up to fast in the ocean so the fish did not have enough time to expel itís swim bladders contents and becomes what we call, bent!

During the cooler times of the year, this is more so a problem as this function of allowing the fish to change depths slows a great deal when the fishís body temp drops and so does the speed of this function.

The example here is of a pterois antennatta lion fish, it was caught at 30 to 35 feet and brought straight up to the surface not allowing it time to adjust its swim bladder contents.

Some fish are more prone then others to slow swim bladder control, though all fish with swim bladders find it hard to control it quickly in winter waters..

This fishes problem is shown by, the intense red colouration indicates the fish is in extreme duress, in side the fish with this much bladder swelling, its blood supply is suffering, its heart has a great deal of pressure on it and it is unable to pass waste from its butt.

It will be dead in 48 hours maybe less!

The syringe needle once exposed to the air dip it into methylated spirits, it has to be sterilised!!!

The fish is prepared in a moist chux with salt water at a compfortable temp ready for the hypodermic to enter its body via the anal hole, never make another hole in its body

The needle pushed into the fish for gas removal at a 30 degree angle to the fishes lateral line.
Gently pull on the syringe if there is resistance it is not in the bladder and needs to be pulled out and gently placed in on a slightly different angle.

The bladder is half way along its abdomen at the top of this cavity!

The fish is fixed.

The fish is in tub pining itself between two objects to expel any air-gas left in it that it can handle itís self now.
