Our innovations can be used for more than just fish passage.
Nobody likes a stressed fish, least of all the fish themselves. Moving fish between tanks or net pens by traditional methods such as aqua pumps often creates a stressful situation for the fish. This can lead to injuries, mortalities, and reduced product quality from elevated cortisol levels in the tissue. We prefer our fishes happy and healthy, and that's why our system is designed specifically to reduce stress, keeping our fish happy, and allowing you a higher quality & quantity yield.
We know that in the seafood industry it is hard to cut costs without sacrificing quality. Whooshh offers a more efficient, hygienic, and space saving way to move fish to, from, or around your plant. Our systems are customized and flexible, so no matter how unique the shape of your plant, we'll know how to fit.
Whooshh tubes work on the principle of pressure differentials. Once an object is inside a Whooshh tube, the slippery flexible tube makes a seal around the object. A pressure differential is created across the object by either increasing the pressure behind the object (push system), or lowering the pressure in front of the object (vacuum system). This pressure differential acts on the surface of the object to create a motive force and since Whooshh tubes have very low coefficients of friction the net force propels the object down the length of the tube. Whooshh tubes can be used as either push (positive pressure) or pull (vacuum) configurations depending on requirements.
The Whooshh accelerator unit employs both pull and push Whooshh tube configurations in one unit. Air and fish are gently pulled into the vacuum chamber of the accelerator. The air is sucked out and connected to the vacuum inlet of the air blower. The fish's momentum allows them to travel through a gentle one-way valve and enter the pressure chamber. Once the valve shuts and the fish make a seal with the primary Whooshh tube, positive air flow from the outlet of the blower is introduced behind the fish thus creating the necessary pressure differential to transport them through the tube.
