Til-Aqua International
Since 1996 we have gained vast experience in tilapia breeding. We defined protocols to produce all-male fry in the most efficient way for the Tilapia industry. Extensive breeding programs resulted in excellent performing all-male Tilapia producing Broodstock. In The Netherlands we specialize in working with Recirculation Technology for Aquaculture. Based on this technology, we have combined our experience and our knowledge of low budget solutions to come up with a complete prefab Hatchery and Nursery Kit. Very easy to assemble with clear instructions; distant as well as local support. All is covered in our intensive training programs to bring you at the same level as we are now. But only in a few weeks` time! We are now in advanced negotiations in the process of transferring the YY technology to various parties worldwide.

About us
Til-Aqua International changes policy
Lessons learned from TiLV and COVID-19
Like many other companies, we are currently confronted with transport issues – limited available flights and closed borders – due to the Coronavirus. The import restrictions that some countries have taken regarding the Tilapia Lake Virus had already severely limited our current operations.
As a result, we decided to change course drastically so as not to lose 25 years of genetic effort: we have put our genetics for sale to interested parties. We believe that transferring our YY technology to countries for local YY production is the best option. These parties would own YY-males and YY-females and would receive the information on how to maintain these lines.
With these fish, they can produce their own YY-males; the broodstock that produces NMT offspring. These YY-males can be both used for own NMT production and distributed to interested parties.
NMT production has since stopped. We will be able to supply our YY-males until the end of December 2020.
OUR MISSION
To supply the Tilapia industry sustainable, well performing All Male Tilapia seed without the use of hormones in the production process.
To supply the Tilapia farmer with ALL instruments needed for a well performing hatchery and nursery: design, systems, training, veterinary services, consultancy and support.
A NEW GENERATION OF TILAPIA FARMING
The sustainable way of Tilapia production
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.
In 2000, when the Til-Aqua YY line was obtained, manual selection for 100% male offspring was initiated. Each and every male and female from the YY line were crossed with respectively an XX-female or an XY-male. Only those fish that produced 100% male offspring in these crosses were kept for the Til-Aqua genetics program. This selection resulted in today’s male ratio: > 99%.
Since 2016 Til-Aqua International is testing the performance of Natural Male Tilapia offspring that is originating from breeding Til-Aqua YY males with other commercially available female lines. This has given excellent results:
