Tilapia you say? Hmmm... This sounds intriguing. I have seen reference to tilapia on the forum, but considering I am brand new here I hadn�t really investigated this potential option to improving my ponds. I will research further. If anyone knows of any studies or real world examples of the effectiveness of tilapia for muck reduction in a pond let me know. The added bonus of food for my LMB and even my family is pretty exciting as well. I have read that the blue tilapia (the kind I should get I�m assuming) die when water reaches below 45 degrees so I guess I would need to stock them as soon in the spring as possible when the water warms up enough and then catch as many as possible when the water starts to dip close to 45 degrees in the fall. Is that correct? I would need to restock every year then I guess? I�m going to look into this further. Thanks for the suggestion.
