Ok so at least we can all agree BM is a retard- hmmm BM??? what else does that stand for....
Anyway on the issue of stomach acid killing fish uuhhh no. Not unless they are in the stomach. The chemical system in a fish is similar to any other predator. When there is an excess of acid ie low ph the endocrine system will sense this and release buffers to bring the stomach to its normal operating range. There is a coating to the inside of the stomach which prevents the "acid" from getting to it. When there is no coating like an ulcer then the acis is a factor. This is not caused by stress, even in humans, we now know that Helicobacter Pylori and not lifestyle causes ulcers. So unless you are going to quick strike rig a half-pound burrito from Taco Bell I would not worry about that.
The issue of lactic acidosis is entirely different and occurs in the muscles when there is not enough oxygen for the cells to use in the production of adenosene tri-phosphate as cellular fuel. When oxygen is lacking the cells will switch over to short term anaerobic respiration which is much less efficient the result of which is less energy per chemical reaction and a greater amount of waste in the form of pyruvic acid. this acid can only be converted with the presence of oxygen. The bigger the fish the harder it is to get oxygen to all the muscle cells that need it. Since the arteriole structure of a fish is limited and the capillary beds are much larger it takes a long time for the new supply of oxygenated blood to get to their muscles. Fish cant increase their oxygen intake nearly as much as humans can in times of need which multiplies the problem. You have all heard this before but think of it this way. Every minute you play a fish is equivalent to you running up about fifty stairs. First fifty- no problem. Second fifty (if your in good shape like a fish) a little more of an issue, after that pure hell. Now at the top of the stairs you are shoved into a tight space where you cant breathe well (a net) and then after that you are held up in the air and asked to hold your breath for pictures. Then all you have to do before you can relax is run back down all those stairs with a limited supply of air left in them and then you can relax. This is why you don't release tired fish over deep water. They do not have the energy left to stay in the littoral zone and recover. They need to be able to sit down at the top of the stairs (shallow water) and chill for a while.
Many people don't understand this because for catch and keep it does not matter if you "play them out" however for good catch and release the fight needs to be shortened and the release immediate. Of course fish that are too green can cause problems as well.
