Is it possible to reproduce Duckweed along with Tilapia in an IBC tank?

<p>As I no longer grow tilapia anymore and only had luck really breeding many of them when I threw some into the larger duckweed tank, I don't consider myself an expert in tilapia breeding in any way. That said, I would expect the more mature fish will be your better breeders as they are already proven.</p>

<p>Yes the 5 grown ones have been my breeders so far, 1 male 4 females. The 25 are what I call my Ferel Fish since they just appeared in the IBC with the big fish. I don't think they are big enough yet for breeding. Would the adult (1+ lbs. fish) be better for breeding? They definitely produce big numbers. I still need to figure the sex of the smaller fish.</p>

<p>I would recommend keeping the 5 full grown ones as your breeders if you happen to have 1 male and 4 female in there (however I'm not sure a 55 gallon tank is really big enough for that.)</p>
<p>The 55 gallon aquarium isn't big enough for 25 breeders!!!!</p>
<p>Just because they had that many babies, doesn't mean you want to try to keep and grow them all out.</p>

<p>I just moved them from a 55 gallon aquarium to the IBC. Figured there were 400 at most. I have about 25 2 1/2 to 3" fish that I'm going to move to the aquarium for breeding. Right now I have 2 330 IBC tanks with the tops used as GB. There are only 5 full grown Tilapia in one withe the 25 smaller fish that I am going to move. I'll probably move the larger fish when the 800 get bigger and need more room. I have a 3rd tank not set up yet for future growth. After my first winter I'm thinking of…</p>

After my first winter I'm thinking of moving the operation to my basement for next winter and grow the fingerlings and back outside for the grow out. This is my first year so I have no idea what I'm going to do with all these fish. But it's a lot of fun. If I had tried to produce fish this year I probably would have had thousands. The two litters I got were 298 and 523. The only fish that I think that got eaten was a Pleco I put in the aquarium. It was about 2" and disappeared.</p> Jeff you won't be calling the…tag:aquaponicgardening.ning.com,2014-03-03:4778851:Comment:5512952014-03-03T19:43:01.859ZTCLynxhttps://aquaponicgardening.ning.com/profile/TCLynx
<p>Jeff you won't be calling them much for long, 800 1" tilapia are WAY too many for an IBC tank. Tilapia should be eating very high protein feed at that size and to provide enough aeration and circulation to keep 800 of them alive in a single IBC tank means conditions won't be good for the duckweed (they like well aerated but relatively still water.)</p>

<p>Tilapia can grow really fast under really good conditions but when over crowded like that, you may wind up with a lot of completely stunted fish. Somewhere between 1-3 inches I would want to have them placed out in final grow out location and I generally like to have 3-5 gallons of fish tank per fish if I am trying to grow the fish out to between 6-12 oz.</p>
<p>If you have one of the Larger IBCs that you have only cut a hole in the top and have it filled to rather close to the very top, you probably still only have 300 gallons MAX in that IBC. How many other tanks do you have ready to go to grade and move tilapia to?</p>
<p></p>
<p>Tilapia fingerlings (from about pumpkin seed size up through when they are about ready to start breeding) have an intense protein hunger, if some are a bit larger than others, they will eat each other.</p>

<p>Just put 800 1" Tilapia into an IBC covered with duckweed. It started disappearing immediately. Hopefully I salvaged enough to start over. I kept feeding them too so it's not like duckweed was all they had to eat. BTW what do you call a 1" fish... fry or fingerling?</p>

<p>Maybe but it really depends on what factor is actually limiting your duckweed.</p>
<p>is it growing slower because of the amount of available nutrients? Too much water flow/splashing? Too little aeration? Or Too much or too little light?</p>

<p>Duckweed can grow amazingly fast under ideal conditions but too often people expect the amazingly fast growth under far less than ideal conditions and they are disappointed.</p>

<p>And, duckweed being a weed has that odd quirk. Do you know what a weed is? A weed is any plant growing where you DON'T want it. Therefore when you DO want it growing there (and it therefore is no longer a weed) it seems to not grow like a weed anymore.<a style="cursor: pointer;"><img src="http://www.bkserv.net/images/Tongue.gif"/></a></p> I just read your duckweed blo…tag:aquaponicgardening.ning.com,2014-02-25:4778851:Comment:5502092014-02-25T04:22:28.799ZJeff Shttps://aquaponicgardening.ning.com/profile/JeffSullivan
