YY-Technology versus hormone use

  • Testosterone will decreased strongly the development of the immune system resulting in high mortality during the sex-reversal and after
  • Sex reversed males will act and look like males (phenotypically males), but they still carry the female genetic makeup: XX (genotypically females). If these sex reverses males escapes into the environment and spawns with natural females this will result in an all female offspring, causing an sex-unbalance in the ecosystem.

Mixed sex not an option:
Increased Food Conversion Rate in mixed sex batches losing energy due to social interaction between males and females
