WHAT PEOPLE SAY ABOUT US

Jon Anders Leikvoll

CEO
Skala Maskon AS

In recent years, a lot of technology has been developed to sort the sex of fish using ultrasound. GreenFox Marine has further developed the technology with the use of high-resolution ultrasound and artificial intelligence aimed at a system for automatic sorting of sexes.

The technology used in the sorting machine for broodstock is both fast and very accurate. This will save many operator hours and lead to us being able to gender-sort larger quantities than we do today. The accuracy of machine sorting also seems to be higher than with manual sorting.

Mowi Genetics AS

Mowi is very interested in automated ultrasound based sex sorting of pre-smolts for improved utilization of broodstock licenses, and potentially improved performance and management of fish stocks in commercial production sites.

There is a significant reduction in mortality among fish and minor wounds / injuries in sex-separated cages.

Fish welfare

With sex-separated cages, increased production is achieved with reduced input factors.

Production

optimization

Full-scale experiments show that both sexes grow significantly faster in sex-separated cages.

Faster growth

By sorting smolts into sex-separated cages, opportunities are provided for optimization production on existing facilities and licenses. Research and studies substantiate that there is significant potential that can be exploited in several ways.

Automated sex determination

of salmon smolt

Gender sorted fish grow faster, both males and females. Males can reach harvest-weight up to 3.5 months earlier than in mixed cages.

Faster growth

More even harvest-weight is achieved in both males and females. A uniform harvest-weight is also advantageous in processing plants.
The growth curve and sexual maturity of the males need not be the only decisive factor for the time of harvesting, as it may be in mixed cages.

Improved control of

harvest-weight

Separated cages result in more even growth and allow better production management.
Production can be adjusted, various parameters can be controlled for the different weights and groups, such as feed adjustments, the light regime, time of harvesting, processing etc.

Improved production

management

Full-scale trials in Norway and the fact that over 50% of all farmed salmon in Chile are (manually) sex-separated show great advantages with this.

Reduced stress for the fish in the cages, provides increased fish welfare.
Increased meat quality due to minor wound damage and better environment in the cages.
Reduction of lice as the fish stay in the sea for a shorter time.
Better feed factor as one can adapt the feeding according to gender and growth phase.
Reduced light treatment as it can be adapted to the different sexes.
Increased sustainability and reduced footprint as you get increased production with less resource use.
Better production base as there is more even growth in gender-separated groups and thus easier to have adapted follow-up to the various groups.

Full-scale experiments in Norway show significant advantages in separating the sexes in salmon cages.

Reduced stress-level and fish welfare is enhanced.
Meat quality is improved through fewer lesions and a better environment in the cages.
Lice infections are reduced, as the fish spend less time in the sea.
Feed conversion ratio is improved, as it is possible to adjust the feed according to sex and growth phase.
The phototherapy can be reduced, as it can be adjusted to the different sexes.
Increased production using fewer resources means greater sustainability and less environmental impact.
The production basis is improved, as growth is more even in sex-separated groups, so follow-up of the various groups can be adapted more easily.
