For those interested,  today, I spotted a few of my new fry swiming in my big tan.  I managed to net two, that I have transfered to my 40 gal. aquarium.  Unlike last week these guys were independant of the other fry.

Seems I read at White Brook Tilapia Farms website the temperatures recommended for each type of Tilapia.

Bob, 

I hope you receive qualified responses. 

I use 3 different temperatures in my fish tanks. 75f for adults under a grow-bed. 80f for frys and fingerlings in an aquarium. 85f for my spawning aquariums. Last summer, I had one adult tank hit 95f. For this summer, I have an 1/5 HP Arctica chiller for 2 of my tanks not under a shade cloth. Life is an experiment.

What's all this talk about heaters?

I have read a number of threads about heaters in systems but was wondering if this was something that us here in South Florida need to concern ourselves with?

What is the optimum temperature for a happy tilapia tank and grow bed?

Would you all suggest some sort of shade cloth over my GB/FT system? The location where I plan to locate my system would get morning and overhead sun through about 1pm then system would be shaded for the rest of the day. Suggestions?

Will tilapia eat oatmeal or any grains in addition to duckweed an would it be healthy for them?

Regards

Sheri:  I am assuming I do have survivors and they are hiding. Thing is initially I saw so many near the surface of the tank for about 3 days in a row and then nothing. Water temp is maintaining a constant 86 to 88 degrees.  With close to 30 fish in the tank I expect more breeding. I now have my 40 gallon aquarium full and the filter runing.  Given the opportunity that is where I will be moving any new young fry.

Dave, it depends on your goal. My experience is that if you leave the breeders with the rest, you'll provide the fish with a number of tasty hors d'ovres, but may have a number of survivors, too. In nature, I believe, 1% survive to adulthood, but that's not just tilapia eating them. Your little fry may be living in the gravel. They can actually swim into it & are very good at hiding.

If you want to preserve the fry, and/or control the breeding environment, you will want to separate the breeders from the others. Also, you'll want to separate the fry from the adult breeders not long after they appear. The mother will stay protective of the young for a week or so, but the males have no emotional attachment to their young.

Jay, why tilapia and not trout?  I lived 33 years in the Easton, PA area.  My sons still are living in the area.  My wife is a Philly girl.

I have 6 pieces of  PVC pipe ranging in lengh from 6 to 14 inches and in diameter from 4 inches to 6 inches.  My home made tank measures 3 ft deep and 4ft x 4 ft capacity is 330 gallons.  Bottom of the tank is covered with aquarium gravel.

cool

I love it when people have different views. I learn and see things I may have missed, 

Dave L,

in the "wild" there are more places for the fry to hide after they start to venture out of their mother's mouth. I would guess that TCLynx has plenty of hiding places for the fry in addition to netting???
