Verlasso’s driving force has been the call for a more responsible aquaculture worldwide. Verlasso is taking the lead in establishing a new model for fish farming, one that’s always in balance with nature. It’s an evolutionary way of thinking about—and raising salmon.
Located in Patagonia, an environment ideally suited to salmon farming, Verlasso is a vital part of the local aquaculture industry. They are committed to supporting the local workforce and establishing a progressive workplace. Verlasso has partnered with leading industry experts to make their innovations a reality. The company's standards are guided by the World Wildlife Fund’s sustainability goals, and they are continuously adapting their practices to ensure harmony with the natural world.
At the center of their fish farming techniques is a breakthrough innovation in salmon feed. With traditionally farmed salmon, four pounds of wild-caught feeder fish are required to to raise one pound of salmon. By replacing the fish oil in the salmon’s diet with yeast rich in omega-3s, they are able to bring the ratio of 4-to-1 down to 1-to-1, while still ensuring the optimal growth and development of the fish. This change is an important aspect of sustainable salmon farming worldwide. Harvest levels for wild feeder fish are already at or slightly above sustainable levels. By using an alternative source of omega-3s, we can ensure the availability of healthy salmon for the foreseeable future.
Verlasso manages its farms to prevent escapes by using a double-net system that ensures the safety of both the salmon and their wild predators. The double nets create a buffer zone around the pens that are less likely to break—and the salmon are less likely to cross. Because predators can’t reach the salmon as easily, they are less likely to harm themselves trying to get inside the pens. Additionally, if salmon do escape, there are no wild salmon populations in the Patagonia region.
Verlasso raises salmon without the use of preventative antibiotics. That means they treat the fish only as needed, if they become ill, under the supervision of a veterinarian. This is consistent with Food and Agriculture Organization of the United Nations’ recommendation.
