SAFETY AND CONTROL SYSTEMS The intensification of fish farms results in higher stocking densities. The new sys­ tems that have been developedmake this possible. Where life support systems such as aera- tors are necessary, problems result from power cuts or other accidental interrup­ tions. In order to keep safe the fish stock and the investment from the interruption of life support, it makes sense to install a moni- toring system. Commonly, simple alarm systems are installed which are triggered by power cuts, and linked to emergency power generators. Unfortunately, these systems alone cannot guarantee the sa- fety and well being of the fish stock. For example, if an oxygen supply pipe is bro- ken, this will not register with the alarm. So, despite a functioning supply system, dissolved oxygen can fall to dangerous levels, stressing the fish. This could result in disease problems later. In the worst case, this could lead to a complete loss of fish stock. Complete, and permanent control of the dissolved oxygen levels of ponds, using in-pond oxygen probes, of- fers muchmore security. With this concept in mind, LINN Germany has developed a comprehensive monito- ring and control system. LINN Aqua-Cont- rol nowworks at more than 200 fish farms in Europe! Control Systems 50 LINN
