Abstract:
1. A holding net useful in a fish farming facility, comprising a plurality of net-sections joined together to create an enclosure for containing fish, said net-sections being made of netting material manufactured from a plurality of filaments woven together, characterized in that: a plurality of electrically-conductive filaments is woven into the netting material close enough together such that a tear in a net section large enough to permit the escape of fish would necessarily involve the breaking of one or more of said conductive filaments; the conductive filaments within a particular net section are connected together in order to form one or more electrical fields within each net section; each of said electrical fields is connected to an electrical power supply and a monitoring device capable of detecting a change in one or more electrical parameters in the electrical field in the event a conductive filament is broken; and an alarm connected to said monitoring device that signals a warning in the event of a change of an electrical parameter outside of a predetermined range of values.
