I was harvesting Tilapia yesterday and found three fish with eggs in the mouths. The eggs were light grey in color. I am assuming that since the eggs were in the mouth they were fertilized. I rinsed the eggs from the mouth and put them in a incubator I made from a jar, five gallon bucket and air pump. My questions are am I correct in assuming the eggs were fertilized? And how long should it take for the eggs to hatch? Any pointers from experienced breeds would be greatly appreciated.

Does anyone here noticed if there is an effect of the day length on the size of tilapia's gonads?

Identifing tilapia for reproduction

Hi Everyone,

I have 15 tilapias and just separated 3 to a new aquarium with the purpose of reproduction.

 

I placed here what i thought could be a male and 2 females, however, I have been analyzing their behavior and i am a bit confused, so i took few videos in order to place the question in few groups.

If anybody can help me i will appreciate.

 

Details of system:

Measurements:

Width: 1 foot

Height: 16 inches

Length: 30 inches

Volume: 94 Liters = 25 US gallons

 

 

Temp: 27 Celsius = 80 Fahrenheit

 

You will see 3 tilapias:

1. Largest one

2. Sort of like singular colour, with fins black/metallic

and Pectoral fins redish.

3. It has more black lines along the body. Smaller of the 3.

 

#2 seems pretty aggressive and chasing the other two.. They have actually jumped out of the aquarium.

 

there is mouth fight, especially between #1 and #2,

 

#3 seems to be chased more than any, though #2 chased #1 even though is bigger.

 

I am starting to think that 1 and 2 could be males, so i am looking for some insights from all of you.

Thanks in advance.

Okay everyone. my male is just very lazy he did not dig a hole/ pit  but instead let them in his pvc and one of my females now has eggs in her mouth.

 Hi Randall,

  $14.00 a lb  for 1-4 inch fingerlings is very reasonable. I bought some of mine for almost $2.00 a piece and it is cost prohibitive for what I plan to do which is raise them for food for us and cook or dehydrate them for chicken feed.

No, Bob,

  I do not have a radio flow filter. I have an in ground koi pond 300 gallon  for my sump that pumps into my fish tank and then directly into my grow beds so they would be pumped into the gravel if any had been hatched.

  I did not put any PVC or hiding places in my tanks past summer. Also I keep the water between 68-74 with the help of solar heat and wood heat and a heat exchanger. It would be very difficult to keep the water in the upper 70's and 80's through the winter and I do not want to burn that much wood... So I have a large aquarium in my house for the breeders. The first time I placed the first batch  in the tank  they bred with in a week...

Randall,

I just tried to find the name of the mountains. I will pick-up a Geodesic Survey (topo map) tomorrow. I should know the name. I have topos of the area, but they are in my RV behind me.

Randall,

Those are mountains. on the right is a pass that leads down into a valley and on to the Rio Grande. You need to stop on out.
