Efficient workflow on board

Marel’s Marine Whole Fish Grader is a modular grading system for maritime environments. The system is supported by Innova software and enables a more efficient workflow on board by size and type grading whole fish in a continuous product flow. This also results in better onshore processing efficiency.

Better handling, higher value

The Marine Whole Fish Grader is a reliable, durable system that delivers high throughput and high accuracy grading. It removes unnecessary steps, resulting in better raw material handling and higher product value.

Accurate onboard grading with advanced motion compensation and improved sizing accuracy enables you to meet market demands more easily and increase the value of your catch. For fresh fish trawlers, accurate sizing also enables you to organize production onshore and provide markets with information before landing.

The system's hygienic design and robust construction ensure it is easy to clean and service with minimal downtime.


The system is applicable for fresh fish trawlers and smaller boats, onboard processing trawlers and freezer vessels.

Dozens of systems have already been sold, with fishing operators around the globe enjoying the combined benefits of Marel’s worldwide service organization, a fast delivery time and low cost of ownership.


Real-time monitoring with Innova

Innova Food Processing Software controls the grading process by setting up grading programs. Innova provides a comprehensive real-time reporting function that gives the operator a complete overview of the production process. Real-time data generates reports on weight distribution, average weights, a packing overview and packing list, as well as the standard overview and lists. This data can be viewed via dashboards.

Based on these valuable KPIs provided by Innova, you can make intelligent decisions on how to optimize your grading and batching results.

Module losses in production are recorded with the optional Innova Overall Equipment Effectiveness (OEE). The reasons for any stoppages are then collated so that it is easy for you to identify and track the most common causes of lost production time.
