Our unique EzeeGrader Flat Fish is a development of the original EzeeGrader designed for finfish. The prototype was designed with Halibut farming in mind but is equally useful for Turbot. It retains the original concept of being a passive fish grader which can be mounted integral to a conventional sweep net for sea cages and larger ponds, or as a grid internally in a shore tank.
Successful trials were conducted in late 2010 with Hallibut PEI Inc. of Prince Edward Island, Canada. The video and photographs on this page show our EzeeGrader Flat Fish mounted as a grid in a shore based tank during final trials in Canada.
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. 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). These loose connectors give the whole grader flexibility allowing for easier handling during use, transportation and storage. An especially useful feature on sea sites where the m2 requirement is greater.
Our production techniques allow us to produce grids with any size and number of apertures to suit different on site conditions. From experience gained during trials we have a guide to aperture size requirements to grade a specific size of fish.
