One problem I see is how to make sure any fish we would hope to farm will survive the pole shift. Tanks are so fragile. The more I thought about this, the more difficult it seemed. How could a tank be devised that would survive the earthquakes we could expect. Wouldn't it just be better to stock a pond (if available at our sites) with the fish we want to farm in the Aftertime? My guess is that a pond would be more natural for the fish, thus they would survive and could be reintroduced to our fish tank systems (which would probably have to be constructed after the earthquakes, etc.). There is a book I am sending for called Earth Ponds - The country pond makers guide which might have information about creating or revitalizing a pond.

The fish will jump out if possible when they feel quakes and tremors, as fish are very sensitive due to that special sensory organ on the sides of the body. Furthermore fish die easily due to shock, they get scared or there is a quick movement or a loud noise and bang! They are literally scared into their own death. I've been trying to imagine the quakes and the fish tanks together, there may be a means after all to minimize any loss of your precious fish-stock. Imagine the following construct:
- tank made of waterproof sail/canvas
- tank hangs in stable, well balanced steal structure
- tank is filled with a minimum of water
- fish are put in the water
- the sail hangs in the structure but not by it's ends
- remaining sail is taken and tight together by it's ends into a tip by means of a thick rope that goes through holes with strong rings
- tip is kept up high above the rest of the tank by tying the rope to a ring in the ceiling (must be reinforced structure) to prevent any sloshing water and jumping fish from being able to get out of the tank; tank is also kept centered this way
- tank is also prevented from swinging by sandbags around it's bottom area

A problem that anyone who has kept fish knows is the pretty rapid degradation of the water with waste and lack of air, so that aeration would become an issue rapidly. Of course, if we kept the fish in the temporary suspended tank for a brief period (just during earthquakes) it seems logical that they might survive. In light of possible poisoning of a pond due to volcanic ash, I do feel less optimistic about using a natural pond as a "holding tank" until after the pole shift. But it would make sense to stock and cultivate a pond anyway, even if merely as a backup. I would think we obviously can't predict conditions exactly at any given site and the more redundancy, the better. It might not be too costly to do at some locations. Assuring that live fish survive is the point.
