That's a very good question. Y'see, fish mining is a very complex process with a long history. Archaeologists have found evidence that the Scots were mining for fish all the way back in the Bronze Age. It often occurs that due to geological shift, what was once ocean can find itself smack dab in the middle of terra. I find that its important to have knowledge of mining safety techniques. As fish are often found deep you will need many props to hold up the mine shaft and canaries to detect gas. Make sure your drills are in proper working order and that the dynamite has been kept dry. The actual extraction process is also difficult. You can't just whale on the fish or you may destroy it fragile form. One should cut around the precious fish and gently lever it out of the wall. Finally, a long grueling treatment process to remove excess rock and other material and you have yourself a precious commodity. I hope you all learned something and will join me next time when I address the age old question of how to parachute for clams.
How do I mind for fish?
