Frequently Asked Question

1 - Are hormones used during the breeding process?

No. No hormones are used during the entire breeding process to masculinize fish reared for fattening.

2 - Is the SUPERMALE GENE transferred from one generation to the next?

No. The SUPERMALE GENE is not hereditary. The offspring is 98% natural XY males. In order for them to produce only males, it would be necessary to treat these offspring with hormones.

3 - Why are OMT fish more uniform in their development than males treated with hormones?

It is well known that male fish grow faster than female fish. Since there are no genetic females within the OMT population (maximum 2%), the male growth will only vary based on normal competition between individuals but not between sexes.

4 - How are these animals sold?

When they are still fry or larva, they are sold as sets. A SET is 1 YY male and 6 mixed sex animals. If the client wants adult fish, one YY male and 3 well defined females of the desired line are delivered. We always pack 10% more animals than are paid for.

5 - Do OMT grow better than males treated with hormones?

In an OMT population, because there are no female genotypes, reproductive behavior is going to be low. There will be no offspring, so the growth rate of the fish will be benefited.

6 - Which have a higher survival rate: OMT or males treated with hormones?

Because OMT have never been treated with hormones, their immune system is in better condition than that of fish treated with hormones. Theoretically, survival rates should be higher in OMT than in those treated with hormones. However, MANAGEMENT makes all the difference.

7 - Is feed conversion lower in OMT than in males treated with hormones?

Feed conversion should be benefited because the feed is only consumed by fish reared in the pond and not the offspring that would result from male and female breeding.
