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.

I'm a newby and just sent a message to all members instead of posting to this board so sorry everyone. But my question is: I see a lot of different info on what to feed Tilapia but can someone tell what NOT to feed them? Thanks

I went to a agricultural school in Santiago that have a aquaculture program supported by the Taiwanese. I was not so much interested in the lecture they had on but in meeting the staff, seeing they ponds and breeding tanks as well.

Made some very good contacts that can bring us YY males and supply us with as many fish as we need. We also got some very nice Red and Nile Tilapia to put in our new breeding tanks, some nice Koi and may get a few Pacu later when we have very big tank.

They did talk about putting their Tilapia into a low salt tank for the last month of grow out to "improve the taste". I think (as my Spanish is not so good) they used 5ppm salt water. Any thoughts?

That may be true about the salt but just a programming note, your plants dont like allot of salt. Salt will also build up over time in the system and be hard to get rid of.

Have any of you folk used Salt to increase water temperature? I have read that they will thrive in fresh or salt water. I live in Phoenix, Arizona where the water temperature (last year) only dropped below 50Deg F during December. My understanding is that if salt is added it will cause the heavy salt water will stay on the bottom retaining heat normally lost to evaporation.

The thing is the pond is small but deep. Fishing is like my only option

castnets work the best, or if you can use a sain net.

it may make them hook shy.. or if you gut hook them (the fish swallows the hook), it's best to harvest

if you plan on fishing (i wouldn't but thats just me) file the barbs off the hooks you plan on using

If I use a fishing line to catch a tilapia, will it still do fine after I let it free again?
