I dream of having land with a pond. Properly managed, it could produce about 50 pounds of bluegills, etc from a 1/2 pond every year, with little input and infrequent work.
I hear that water quality and, to a lesser extent, water chemistry has a huge impact on taste. I've sort of noticed that in certain lakes compared to others.
I challenge you to a duel, thems fightin' words. Fried catfish is one of the greatest things on the planet (mind you not terribly healthy).
