Cage lowering and rising is done by air discharge or supply, which regulates the water-and-air balance in the system of ballast tanks. The device is equipped with a ballast compartment with kingston valves, and ventilation valves operated manually or by a pneumatic actuator.
The cage can be stopped at various intermediate depth positions before reaching to the surface. For fish species with close-type swimming bladder, it is important to adhere to a slowed down procedure of rising, with intermediate decompression stops. |
