...also commonly known as microchips are frequently used with fish as for many other purposes. Because of the comparatively low price it is possible to equip large numbers of fish with These transmitters  at reasonable cost. Adverse though is the short reach of the signal. The fish must therefore either be scanned manually or has to pass some bottleneck like a fish pass to detect the signal which is triggered by a electromagnetic impulse. Known applications are listed at the bottom of this page.
