Put preservatives in the bottle with the fish. Or freeze it.
The biggest part of fish preservation is the clean up of pollution. Another thing is to stop over-fishing in areas where fish reproduce.
You can usually freeze them in a big freezer. Then when you take them out let them thaw.

That depends on the size of the fish and the size of the container. It is the build up of ammonia and depletion of oxygen that kills fish under these conditions. It is possible to keep some small fish alive in a small container for a while but use your common sense and observe the fish. If you see them stressing, change some water.
Keep them in the refrigerator but not in water, just in a sealed container.
