Bedre foder resulterer i bedre mad til os alle
Hos BioMar forstår vi, at rejsen til enestående fisk og rejer begynder længe før, den når bordet, og den starter med det foder, der giver næring til fisk og rejer.

Guar, or Cyamopsis tetragonoloba, might not sound glamorous, but it powers a surprising range of industries. From your pantry to petroleum, and even into fish feed, this underappreciated crop is quietly shaping the world around us.
Guar thrive where many crops fail
It’s a fast-growing, drought-resistant legume native to India and Pakistan. In fact, India produces around 80% of the world’s guar, much of it in the arid state of Rajasthan. It thrives in poor sandy soil, high heat, requires very little water and matures quickly in just 90 to 120 days — a miracle crop for regions with tough growing conditions.
So while it’s not the fastest crop (like some leafy greens or vegetables that mature in 30–60 days), guar is quick for a protein-rich, industrial-scale crop.
But the real magic happens when the seeds are processed into guar meal, a natural thickener, stabilizer and emulsifier that’s now essential in food, pharmaceuticals, cosmetics, textiles — and aquaculture. Guar gum is a hydrocolloid, meaning it can absorb up to 8 times its weight in water, which makes it valuable as a thickener. Like other legumes, guar fixes nitrogen from the air into the soil via symbiotic bacteria in its root nodules.

In a world where aquaculture must grow without increasing environmental impact, guar checks a lot of boxes:
Plant-based: Helps reduce reliance on fish meal and fish oil, supporting sustainable aquaculture.
Low water use: Requires minimal water and chemicals, making it ideal for climate-stressed regions.
Soil restorer: Enhances crop rotation cycles and soil fertility by fixing nitrogen.
Non-competitive land use: Thrives in marginal soil, reducing fertilizer needs for subsequent crops.
Biodegradable: Leaves no synthetic binders in water, minimizing environmental impact.
In fish farming, guar might just be a sustainable game-changer. Guar gum binds fish feed pellets together, preventing disintegration in water—leading to less waste, cleaner water, and more efficient feeding. Meanwhile, the leftover guar meal after gum extraction contains up to 50% protein, making it a viable alternative to fish meal, a major sustainability concern in aquaculture. Additionally, guar enhances digestion and nutrient absorption in aquaculture feed, further boosting fish health.
This bean is quietly changing the world—one pellet at a time. In the quest for more sustainable aquaculture, guar isn’t just a binder; it’s a bridge to better feed, cleaner water, and more resilient farming systems.

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).

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.
