The advantages:

"Potential of Tilapia YY technology" (Global Aquaculture Advocate, 2014)

YY-Technology versus Hormone sex reversal

- No use of hormones during the production process of the YY-males

- No use of hormones in your production process

- Easy to use: stock your broodstock as usually - Works ALWAYS in your farm: always > 95% males

- No risk of hormones in consumption fish

- No daily contact with hormones

- No environmental harm

- No ecological impact

(masculinisation of females (these phenotypically males are genetically still XX-female!) --> natural environment (restocking or escapees) --> production of only females in the natural environment)

- No decrease in fish resistance: testosterone weakens the fish defense system (Harris_and_Bird, 2000). The immune system isn't build up during the first weeks of fish life. Especially the protection by the skin (mucus) is lost giving parasites free access.
