Rainman,
Nothing yet but I have a lot of algae. I'm thinking that they need to get bigger and most importantly... Spawn. I just hope that I don't have to wait until the end of the season for the expected results.
Blaine,
I'll bet once it starts to really warm up your tilapia will kick into high gear. We've had abnormally cool temps as you know. I'm looking forward to hearing your report in a month or two.
BTW I'm now filling up my biggest pond. I'm doing repairs myself. I'm using Aquashade this year since all my fish are larger, monosex, and on feed in the pond. Perhaps if I have some algae problems along the shore I will give Tilapia a try.
The last grass carp I had liked the feed more than the chara. No grass carp for me.
