A fish farming net having conductive wires integrated into the filaments of the net. The conductive wires are arranged in circuits, each of said circuits defining a field connected to an electronic apparatus that monitors a certain electrical parameter of the field. The wires of each circuit are arranged in a pattern whereby the wires are close enough together that a hole large enough for fish to escape will necessarily break one of the wires. In the event the circuit is broken, the monitoring apparatus detects a change in the electrical parameter being monitored and signals an appropriate alarm.
