The right fish handling tools can reduce labour cost and improve production. Grading and fish harvest for example can be labour intense events, which can induce mortality and stress if done wrong. Therefore, it is important that during the design phase, these events are already considered. Harvest pipes, crowding devices and proper grading equipment are therefore vital in a design. During the years we gained experience with the existing fish handling equipment, sometimes the right product was not available and we had to develop our own. A grader for live catfish, pneumatic feeders and grading screens are examples of these products.
