Our technology
Mixed sex culture has been a common practice around the world for decades. However, with growing interest and research a focus has been made on the production of monosex population.
All male production have many benefits which makes them more suitable for aquaculture, such as:
-
High growth rates and feed utilisation efficiency
-
High tolerance to severe environnemental conditions
-
Reduced aggressiveness
-
Uniformity of the batch at harvest size
-
Control of the reproduction during growth out phase
Different methods are available to produce monosex population.
At GF-Hatchery, we are offering an all male production without any hormonal administration with the YY-technology.
The main advantage of our technology is his easiness. Indeed, there is no action, preparation, special product to have in mind, everything is simple!
When we supply broodstock, we are offering super male (with two Y chromosomes) who needs to be kept apart from the main population.
Our super males can be crosser with mixed sex population supplied by us or by local population.
The only requirement for our technology is different tanks and the knowledge of sorting male and female as explained below
The end product of the YY-technology is a complete normal male with normal XY-chromosomes.
Each new generation of our new breeders are individually tested and yearly improved based on a rigorous breeding program.
