Seafood Waste Management Solution: Fish Silage Processing
In the aquaculture industry, all dead fish, fish trimmings, and by-products from production must be handled in accordance with regulations.
Dead fish and fish trimmings represent a significant and valuable resource. Consequently, it is important that this resource is handled correctly. Dead fish and trimmings must be processed and stabilized quickly before storage. The marine by-products are organic and as such must be treated as fresh products. Our seafood waste management system allows for easy and convenient fish silage.
ArcticFlow has developed an optimized ensiling process for marine by-products. The entire process is controlled by a fully automated PLC-based control system.
Fish silage preparation starts with the by-products and dead fish are ground into a homogeneous and particulate mass with a particle size of less than 5 mm. With our processing plant for dead fish silage, your company can save money and create extra profit from what has previously been waste. When optimal stirring conditions are reached, formic acid is dosed automatically with continuous pH measurement. In this way, the silage has the desired pH, preferably in the 3.2-3.7 range.
When the silage is stabilized at the desired pH level, it is automatically pumped into a storage tank. The user can easily enter the desired set points for pH, grinder tank level, and running times for grinding and stirring via a touch screen. This enables the process to be easily adapted to the individual plant. Moreover, the user can choose between running the process automatically or manually.
The advantages of fish silage processing units supplied by ArcticFlow include:
- An optimized ensiling process provides a silage product of high quality
- An automated PLC-based control system with continuous pH measurement frees up time for the customer
- A service-friendly and dry-pit grinder pump made from acid-resistant steel provides a long lifespan
- Grinder tank designed for easier hygienic cleaning meets the demands of tomorrow
- A complete and turnkey unit built for a fully integrated fish silage production process demands less planning, makes project cost visible and improves HSE compared to a more manual process
Turnkey silage plants
Complete and turnkey silage plants built for a fully integrated silage process require less planning, make project costs visible, and HSE is improved compared to a more manual process.
ArcticFlow can deliver a turnkey system adapted to the customer’s needs. For example, if you want a specially adapted silage plant for silage of salmon.
The facility can e.g. consist of a coarse grinder, a grinder tank, a cabinet for acid dosing, an acid tank, and a storage tank for silage with a circulation pump.
The entire facility is controlled by a fully integrated control system. The control system has functionality for remote updating, which is used when upgrading the control system.

What do our customers say?
Ensiling our dead fish has not always been easy. These are primarily broodfish, which are large fish with very tough skin and strong bone structures. This means they are difficult to grind into fine particles. But with ArcticFlow’s ensilage process, we finally managed to produce good silage. ArcticFlow delivered a complete processing plant to our full satisfaction.
