Hey everyone,

Im continually looking for ways to better utilize my property and decided to put my small pond to better use. There's already a small population of bluegill, bass, and catfish but they are more for recreation. I found a lot of information on cage culture and the amount of fish you can raise is incredible. Would definitely be a great way to have a year round supply of fish cause in the winter time I can't find those things. I was just wondering if anyone had any experience in farming fish in cage culture. Everything I've ready says fish are generally ready in 2 growing seasons. OK, that's great, but I've searched everywhere and can't find out how long a growing season for fish is. Does anyone know how long a growing season is? And say you raise 400 bluegill, after you've started harvesting, how do you replinsh your supply? Just buy more fingerlings? I'd rather have them reproduce.

Roman Campbell : I Think that at that density you are going to be supplying supplemental oxygen to the water via some kind of pump that would have to run

near constantly, any failure of the pump broken shifted hoses loss of power would leave you with dead fish / expensive fertilizer !


There is also what your expectations are for a food source for your fish and the increased number of water and water airborne predators to consider!

As I live in New York my limited information will do you little good ! Best Big AL

Well I have done some research and some people say you need to aerate the cages some say you don't. I don't aerate my pond and the fish are fine. The pond water gets replaced every time it rains so maybe that helps. Just wondering how you could replinsh your stock after you harvest.
