Hello from Arizona!

 

I would like to get the opinion of the folks raising tilapia in AP (both commercially and as a hobby) which do they prefer to do. Use the offspring from a breeding pair of different species to produce "all male off spring" (hybrids) for the grow out OR use a pure strain and use both the male and female offspring for the grow out.

I've read that to produce "all male" fish, the breeders (Mommies and Daddy) need to constantly be replaced because after a short period of time because the hybrid offspring become weakened and hard to grow out and that this fish is somehow NOT as healthy for you to eat as a "pure strain" fish.                                         Therefore it is best to use a "pure strain" and just grow out males and females together and somehow sheild the bottom of your grow out tanks to keep the new females from getting to their eggs that fall to the bottom of the tank.

I am in the "research" mode of a future project and just trying learn as much as I can. I would really appreciate some feed back because something doesn't seem right to me. I feel I'm missing some thing in regards to "hybrids" being un-healthy to eat. Just because two Tilapia are from different parts of the world, the fact that they can inter-breed and produce all male off-spring should be ok to eat right?

 

Anyways, have an awesome day everybody!

I think it's more down to what the fish eat, Tilapia that eat lots of corn based food hardly contain vitamin b12 (the whole reason for eating fish) natural algae food(something like spirulina) contains more vitamins and essential amino acids ect...(1g algae = approx 100g vegetable mater) producing much more healthy fish that's good to eat...

All Male Tilapia - without hormones: 
  • No hormones in consumption fish
  • No daily contact with hormones (feeding)
  • No environmental harm
  • No ecological impact (masculinization)
  • No decrease in fish resistance caused by the use of testosterone
