Fish oil from trimmings is a success story in the world of sustainable resources — turning what was once discarded into something both practical and powerful. Derived from the parts of fish not used for human consumption such as heads, skin, bones, tails, and viscera — this by-product is now a valuable ingredient in everything from aquaculture to agriculture, pet food, and even renewable energy.
Trimming sources: Wild caught fish by-products and aquaculture by-products
High energy density: Trimmings oil is highly energy-dense, which makes it a great source of calories for fish, supporting faster growth and better fat deposition in farmed fish, especially in the early stages of life.
In recent years, as aquaculture has grown, it also contributes a significant share of trimmings. Farmed fish such as salmon and trout, when processed for fillets, generate similar by-products that are used to extract oil. This source is increasingly important as wild stocks are regulated and limited. Most trimmings oil is traditionally derived from the by-products of fish processing for human consumption — heads, skin, viscera, and tails from species like cod, herring, and mackerel. Predominantly small, fast-growing, short-lived pelagic species with high oil content and limited value in direct human consumption markets.
Fish intended for direct human consumption is typically processed to enhance convenience and speed for consumers. This process results in valuable by-products accounting for 30-70% of the total fish weight. Fish trimmings oil is a rich source of essential omega-3 fatty acids, particularly EPA and DHA. These nutrients are important for fish health, supporting growth, immune function, reproduction, and overall performance. Aside from omega-3s, the oil can contain vitamins A and D — especially when liver parts are included in the trimmings.
The oil isn’t just made from one type of fish. It can come from various species, such as salmon, mackerel, sardines etc. This type of fish can influence the nutritional profile of the oil, making it a versatile ingredient in fish feed formulations.
Not just for fish: Fish oil from trimmings has found a home in a wide range of industries. The oil can also be used in pet food, poultry feed, and even bio-fuels, showing its versatility as a byproduct. Moreover, some companies are converting fish oils, including those derived from trimmings, into renewable energy sources as an alternative to conventional fossil fuels. Through transesterification, fish trimmings oil can be processed into bio-diesel. Before electricity, fish oils were used in lamps as fuel.
Production of fish trimmings oil is subject to strict regulations in many countries to ensure safety and sustainability. It's produced in large quantities in places like Norway, Peru, and Iceland — wherever fishing is a big industry. Modern production methods include molecular distillation to remove heavy metals and contaminants, making it a super clean raw material. Because of its sensitivity to heat and oxidation, the oil must be handled and stored carefully to protect its nutritional value. But when done right, it stays stable for a long time without going rancid.
Trimmings oil represents a sustainable solution by utilizing these nutrient-rich parts that would otherwise go to waste, helping to meet the global demand for protein and essential fatty acids without increasing pressure on wild fish stocks.

UdforskStay in control of oxygen fluctuations
In fish farming, large fluctuations in the oxygen content of water have a negative impact on the well-being of the fish and consequently on its growth. High water temperatures or rich vegetation in the water are important alarming factors to observe, especially in summer periods.

UdforskEnsuring optimal oxygen levels
Just like humans, fish need certain levels oxygen to thrive. Sub-optimal oxygen levels may have consequences on the well-being of the fish and consequently on the economic outcome of a fish farm. Active observation and assessment are required to take the necessary actions in good time.

UdforskVejen mod et bæredygtigt fiskeopdræt
Their aquaculture journey began with curiosity sparked by an unused pond on his father’s land. With no prior experience in fish farming but a strong background in finance and business, Lauris Apsis saw an opportunity to create something meaningful. Recognizing sustainability as the key to long-term success, Lauris and his Finnish partner, Salmela-Yhtiot Oy founded Blue Circle (Zivs uz Ledus), a Latvian farm dedicated to producing premium Arctic char using cutting-edge recirculating aquaculture systems (RAS).
