Tour operators occasionally offer freshwater fishing expeditions. If the fisherman's wife and children did not behave themselves the fish knew it and would run away. A woman must never at any time touch a fisherman's equipment. A woman should never go near a fishing canoe lest she defile it. When the fisherman packed his gear and left home to go fishing his wife never asked where he was going or made any mention of fishing.
Fish have keen hearing and can overhear conversations.
During the time the husband was absent the family was placed under kapu. They could not quarrel, they could not fight, indulge in loud talk, loud games, or filthy talk. If the family quarreled the fish would run from the fisherman's bait. If they indulged in hilarious play the fish frisked about his bait and swam away. If the wife was entertaining a male guest while the husband was absent the husband would know immediately.
