The production process begins when healthy and mature selected females are "stroked" for their roe. This is fertilized with milt from first class selected males and result in spawns.
The spawns become fry by spending the following months in a hatchery under careful supervision under the best nurturing conditions. With a large yok sack on its stomach, the fry emerges from the egg. This provides their food for the first weeks of life. Thereafter the first careful feeding begins. Over the coming year the fries will develop into smolts weighing 50-300 grams, and ready to be placed in the sea.
It spends one or two years in open sea cages where the current provides a steady flow of fresh seawater, fed up to required slaughtering weight. During this growth phase the farmers monitor the fish carefully and adjust the quality and quantity of feed in line with water temperature and other biological conditions.
When reaching a size that is in demand in the market, it is slaughtered and prepared for sales at special packing plants.
