EWEST,

Will send the Tilapia paper and address. I would really like to read any articles related to this topic. The more info the better. Thanks.

Woody,

As you probably know by now, I'm not a pro-fertilizer person, but it seems to me that taking a pond to max capacity with fert or any other means is not a good long term practice. We all need margins, myself more than others.

I found it interesting that the Tilapia survived the DO crash. From what I have seen of them, they can survive, even thrive, under conditions which would choke an ordinary fish. The only thing they can not tolerate is cool water.
