How we Started
One evening, as we sat relaxing, we began discussing alternatives to synthetic fertilisers for our coastal farm.
Our thoughts turned to our grandparents, both well known in their communities for having some of the best vegetable gardens around.
What was their secret - Fish!!
They were both keen fisherman who made a habit of burying fish waste in their gardens. While that approach wasn't practical for our farm, it sparked an idea. Can we make a liquid fish fertiliser? After extensive research, we decided to trial fish hydrolysate as a natural alterative.
What began as a small venture quickly grew into something much bigger. Today we produce FishBru, an organic fish hydrolysate using 100% locally sourced fish waste, sustainably caught under commercial quota.
This photo was taken in February 2025, just weeks before a drought was declared in Northland – the lush green pasture is the result of one application of FishBru.
Smarter Farming Starts here!
FishBru, a liquid fish fertiliser is proudly crafted on the outskirts of Whangarei, New Zealand. We are passionate about creating a high quality organic fish hydrolysate concentrate that delivers exceptional results.
What is FishBru?
FishBru is a premium natural liquid fish fertiliser and soil biostimulant made from fish hydrolysate. Using a cold-processing method, we break down whole fish into highly available nutrients while preserving valuable organic compounds and omega-rich lipids.
The result is a powerful, biologically active product that feeds both your plants and your soil. FishBru delivers essential amino acids, vitamins, trace elements, and organic matter to support strong growth, improved nutrient uptake, and greater resilience to environmental stress.
How does FishBru Work?
FishBru supports the natural relationship between plants and beneficial soil fungi. These fungi extend fine thread-like structures (hyphae) into the soil, increasing the plant’s access to water and nutrients. In return, the plant supplies the fungi with sugars.
This symbiotic relationship improves nutrient efficiency, enhances soil structure, and helps retain moisture. Strong fungal networks contribute to healthier soils and enable pastures to better withstand dry conditions.
By strengthening soil biology, FishBru promotes healthier plants and livestock, improved soil quality, and overall farm productivity.

Testimonials
We have a lifestyle property just out of Whangarei. We had FishBru applied to our paddocks in early May 2025. By June we noticed a massive increase in Winter pasture growth. By September, we hadn't had to feed out any supplementary feed, which was a first for us. Our cattle had not lost any condition over winter, in fact, they'd packed on the pounds and had amazing shiny coats. The only issue is the neighbours cattle damaging our boundary fences, because the grass is truly greener on our side of the fence. We'll have FishBru applied again next year for sure. AM
I have used FishBru twice in the last year, and I am very happy with the results I have seen. The grass is healthier and thicker where I have applied FishBru and the stock graze the paddocks down better and are more content. Its also easy to transport and spread MM
On our coastal property east of Whangarei, we have noticed significant improvements with just one application of FishBru. Our animals are much more settled, their coats are shining, and the overall animal health is greatly improved,. Our carcass yield has improved from an average of 54% to 57%. At $8.00 per kg, that's an extra $144 per head. In the declared drought of 2025, our grass just kept on growing. RG
