在黃刀鎮體會零下二十度捕魚
在黃刀鎮的一種旅遊項目就是帶著遊客參觀當地人冰上釣魚（ice fishing）的場景。在冰層鑿開一個洞之後，便將魚鉤置入冰層之下。聽說在冰層下湖水中的魚，因為食物稀缺，幾乎不用魚餌，一些餓得發慌的魚就會上鉤。
不過要以捕魚作為養家活口的職業，就不是簡單鑿個洞而已。當地的漁夫會根據經驗，知道偌大的大奴湖哪兒會有比較多的魚群。於是就在那兒鎖定捕魚。大奴湖面積27萬平方公里，只比比利時少了五千平方公里。
而這些魚群較多的湖區，往往並不接近城鎮。我們本來以為不遠，但由漁夫以雪上摩托車（Snowmobile）載著，也花了兩個小時才抵達目標區。
漁夫在目標區已經放置了小箱子，箱子上有著竿子，上頭還有編號。掀開箱子，就是一個大約直徑一公尺的洞。因為風寒的關係，這個洞在一天之後也挨著冰封。漁夫於是用尖刀將封住的冰挫開，下方就是湖水。
這冰上的洞窟底下可有玄機，是可以捕獲漁夫全家、甚至全公司一天生計所需漁獲量的大網。露出冰面的是漁網頭，漁夫將網頭鬆開，接著再往一百公尺遠處的另一端網頭如法炮製。
這兩處網頭就是冰層下方大漁網的兩端。當網頭鬆開，漁夫就開始收網。收網的過程也就是捕魚的重頭戲。這時候就看到一條條的大魚被抽出冰面。有些奄奄一息，有些依舊生龍活虎。但因為冰下溫度與氣溫相差太多，即使活龍般的大魚一旦到了冰面，立即成了僵硬的標本。
有些魚在冰層下被漁網勾住就已經死去。這些魚就被漁夫順手拋棄在湖上。成為人們口腹之外的自然迴圈。
這種捕魚的方法是定置式的。當天捕魚結束之前，漁夫再將漁網放回湖下。第二天漁夫再來採收。
Experience 20 degrees fishing in Yellow Knife Town
One of the tourist programs in Yellowknife is to take tourists to visit the local scene of ice fishing. After a hole was cut in the ice, the hooks were placed under the ice. I heard that in the lake under the ice, fish is scarce because of scarcity of food and almost no bait, and some hungry fish will be hooked.
However, to use fishing as a career to support the family, it is not simply to create a hole. The local fishermen will know from experience that there will be more fish in the big Slave Lake. So it was locked fishing there. Da Nu Lake has an area of 270,000 square kilometers, which is only 5,000 square kilometers less than Belgium.
And the lake areas where these schools are more often do not approach towns. We were not far off but it was carried by the fisherman with Snowmobile and it took two hours to reach the target area.
The fisherman has placed a small box in the target area. There is a box on the box and there is a number on it. To open the box is a hole about one meter in diameter. Because of the cold, the hole is still frozen after a day. The fisherman then used a sharp knife to defeat the sealed ice and the water below it.
This ice cave can have a mystery underneath it. It is a large net that can catch the fisherman's family and even the company’s daily catch. The fishnet head was exposed on the ice. The fisherman loosened the net, and then proceeded to the other end of the net at a distance of 100 meters.
The two nets are the two ends of the large fishing net below the ice. When the net is released, the fisherman begins to collect the net. The process of collecting nets is the highlight of fishing. At this time, we saw a big fish caught out of the ice. Some are dying and some are still living. However, because the temperature under the ice and the air temperature are too different, even if the live dragon fish reach the ice, it immediately becomes a rigid specimen.
Some fish have already died under the ice and caught in a fishing net. The fish was thrown away by the fisherman on the lake. Become a natural circle outside people's diet.
This method of fishing is stationary. Before the end of the day's fishing, the fisherman put the fishing net back under the lake. The fisherman harvested the next day.
