Beyond Fishery develops the technical applications of aquaculture and cooperates with major global suppliers in order to meet more and more demands for healthier food. And we hope to achieve product conversion with less resources and the smallest ecological area.


Salmon farming

The first stage: Salmon eggs


Farmed salmon is fertilized in fresh water, which is the same process as wild salmon. Broodstock providing the eggs and sperm are selected from seasite production stocks to reproduce the offspring. The fertilized eggs are placed in an incubator kept at 8 degrees Celsius for about 60 days. The eyes will be clearly visible around day 25.

Hatching:

When the eggs get ready to hatch, the baby salmon will detach from egg's soft shell. At the same time, yolk sac which provides food for the first few weeks attached to baby salmon. Baby salmon are about an inch long and are called "Alevins" during this process.

The second stage: Fry

After most of the yolk sac has been absorbed, the fry will be initially fed. The initial feeding period lasts for six weeks. As the fry grow, they will be sorted and transferred to larger tanks.




The third stage: Parr

After living in freshwater for 10-16 months, the parr can be transferred to seawater by wellboats. Parr will have a series of physiological phenomena during the transition from freshwater to seawater, which we call them "Smoltification" .The abdomen of parr will show a silvery luster, and the back will turn blue-green, and they will gradually transition into smolt.



The fourth stage: Adult salmon



Adult salmon will grow in cages, which are large closed nets suspended in the sea by floating devices. In addition to a stable anchorage, net fences need to be cleaned regularly and appropriate measures to prevent the escape of fish. Salmon are also classified as they develop and grow in the cages. A year after being transferred to ocean cages, the first batch of salmon can be harvested.
