BSB are very suseptable to embolizing also.This is when the air bladder expands due to the release of pressure due to being brought to the surface.The air in their bladder will double in size every 33 feet they are brought up.This is why they float belly up .The pressure in their belly also puts pressure on their central nervous system somewhat paralyzing them.

If you really want to be ready to quickly release the fish you need a three way swivel some 8lb test and a five pound rock cod sinker.
Take a very small hook tied up with a couple of feet of the 8lb, tie to the threeway.Tie your heaviest line available to the swivel and a snap swivel to the threeway for the weight.
Lower the bsb slowly to the depth you caught him at and troll as slowly as possible in no time the fish will revive and break the 8lb and be fine.

If the bsb is very small you will need to hook the fish under as small a bit of mouth skin you can ,lower the fish and yank sharply on the lineto break the hook away.

this works for small rock cod too and if your gonna fish them you will catch small ones that are so small to be not worth filleting.This has to be done quickly.once recompressed the fish will be able to swim off like you caught it in ten feet of water.If you have ever caught reds up in the north in real shallow water they will swim just like a calico when released.Recompressing them does this same thing but be fast about it.
This is what they do for divers in recompressure chambers.They increase the pressure to make the gas bubbles of nitrogen that have formed in your body from too much bottom time...then they gradully let the pressure return to normal.Fish don't need to have the recompression chamber ,they live in one just, put em back where you found them.
