Doomwatch S01 E11 The Battery People

Doomwatch hears that in south Wales, tough ex-miners have taken to drinking gin instead of their usual beer, and are unresponsive to their wives' sexual advances, instead preferring to attend secret cock-fighting tournaments. After Quist is asked by the minister to look into the situation, as it is happening within his constituency, he and his team trace the cause to the local fish farm, which is using a special chemical to dissolve the bones in the fish. Unfortunately, this has led to the workforce becoming sterile. Original Broadcast Date 27th April 1970
