| JR, your point about the water temps and bacteria is not complete in it's idea. The reason is, here, we have cool tradewinds blowing in the winter time. Placing the pond in the path of those breezes will cool them as well, just like having a chiller. So we can actually control water temps better and have longer growing seasons and fasting winters whenever we want or see the need. A shower and/or waterfall will cool the water dramatically, especially isnce the hudnity is low this time of year so eveporative cooling is increased along with the winds. We have to be careful not to overdo it actually, and cause temp fluctuations that are too severe.
I can get my pond temp down to about 55-60 or even less if I want, and with a large swamp cooler I can drop the temps down into the low 50s or high 40s. So the bacteria strains and fat can go if we want them to. What I do is wait until they are about 3 and put them into a little deeper winter with a one or two month fast to get the fat off. Part of being able to do that depends on location. Down by the beach, it is warmer and harder to do. Water source plays a big role in that, which is why I use inland soft water wells and mountain water.
The mountain well and stream water is so cold here you cannot swim in it. The ocean water keeps the land too warm. Get a few miles from the beach, and it is a whole new ballgame. Tropical forests and mountains have such incredible resources in them, and varied conditions, it is the best place in the world to raise or breed koi imho. I can have a perpetual summer or a perpetual mild winter if I want. Under the canopy of the rainforest, if you have a cold spring or well, you can have a US fall and winter condition all year. You can get whatever you want, and the springs and wells are so unpolluted here, I cannot think of a better breeding place. Bacterias are a concern near the beach, and in the US, here we are unpolluted. |
