Our unique EzeeGrader is a passive fish grader, integral to a conventional sweep net. The device consists of a series of rigid grids made from injected Polyamide, circular in profile and with apertures of a predetermined width, which smaller fish swim through. The larger fish are harmlessly contained within the sweep net. 
The smooth flowing surface of the moulded Polyamide grids, and the circular profile prevents any possible scaling or snagging of the fish passing through. This eliminates physical damage and stress to the fish, ensuring a higher quality end product for the farmer. The lightweight Polyamide material ensures that the product is sturdy and durable, while still being light and easy to use. The rigidity of the grid stops distortion of the apertures preventing larger, stronger fish from pushing through or the apertures collapsing to trap smaller fish.
Each rigid grid is connected to it’s neighbours by our unique loose connectors. Located on each side of the grid, they align with the neighbouring grid allowing the EzeeGrader to be made to any size (m2). The greater the surface area of grids within a sweep net, the more efficient and accurate the size grading result. The loose connectors allow each grid to move independently of it’s neighbour in both horizontal and vertical planes, allowing for easier handling during use, transportation and storage.
Our production techniques allow us to produce grids with any size and number of apertures to suit different uses or species of fish. Our unique conversion calculator can identify exactly the aperture size required to grade a specific size of fish. With this versatility we welcome enquiries from all sectors of the fishing and aquaculture industry. 
We aim to work closely with customers to identify and provide the best possible product to increase profit and productivity with the minimum of effort.
