Even a relatively sedentary
fish like the lingcod can rack up a large number of detections by swimming back and forth or
circling in a small vicinity within the receiver's range — or simply by holding still and hovering
over a given spot within that range while the receiver tallies pings.
Over recent years, the lure of the nearby
fish and chip shops and supermarkets offering pre-packaged, on - the - go snacks have tempted teenagers off - site, and a vicious
circle has been created where lack of customers has meant less money for schools and caterers, leading to less meal choice and drab dining areas in need of a spruce, leading to — yes, you guessed it — more children taking their money elsewhere.
