Water Grader

The water bath grader is ideal for the gentle handling of oyster seed.  Currently in place in several nurseries throughout the world, it is able to separate up to five grades of seed at a time. With all action taking place in water, this method dramatically reduces the stress and shock put on the small seed and helps to reduce mortality. Available in large and small models, it works well for seed collection operations or oyster farmers collecting their own seed.
