Til-Aqua does not use any hormone in their production process. Only temperature change in the first days after hatching is used to change sex from male to female.
The end product of the YY-technology is a complete normal male with normal XY-chromosomes. (This is in contrast with hormone sex-reversed Tilapia where 50% of the phenotypically males is still genetically female with XX-chromosomes.)
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 (Harris and Bird, 2000)
