前段時間，全球最大的三文魚生產商Mowi公司發佈了一則“懸賞通緝令”，通緝物件正是自家養殖場逃出去的2.7萬條三文魚，賞金則是一條500挪威克朗，約合人民幣346元。
2月9日，位於挪威特羅姆斯的一個養殖場中，工作人員發現其中一個圍欄外圈受損，導致部分三文魚逃逸。
剛開始以為逃逸的不多，誰知一清點，逃走的數量高達2.7萬條，成該地區迄今為止最大的逃逸事件。
And, escapingThe average weight of salmon has reached 5.0 kg, and it has reached the stage where it can be caught and soldFinish.
養殖場可謂是損失慘重，可就是在這樣的情形下，養殖場依然開出一條500的懸賞，要是全部抓回來，還將損失1350 萬挪威克朗。
This decision is incredible, is it to continue to sell after being caught?
Obviously it's not that simple, it's all about catching the fish at all costs, and that's moreConcerns about farmed salmon "contaminating and impacting" wild salmon.
Salmon farms in Norway are cultured in cages with Atlantic salmon, a species of anadromous migratory fish.
To put it simply: it spawns in the upper reaches of freshwater, the juveniles grow to a certain stage, and then return to the sea to live, and when it is the breeding season, they must return to freshwater again to reproduce the next generation.
Therefore, the life of farmed salmon is probably spent like this:
In their infancy, they live in tanks or artificial canals on land, and later they grow up in cages at sea, where they are caught, sliced and shipped around the world.
The cages can be square or round, 10 to 0 meters in diameter, generally 0 meters deep, and multiple cages will be placed side by side.
The salmon that escaped as mentioned at the beginning escaped in a cage.
In Norway, Atlantic salmon are also found in the wild, but wild populations are rare.
According to the 2024-year survey, the number of Atlantic salmon in the wild has reached an all-time low and can be described as "endangered".
If farmed Atlantic salmon are successfully integrated into wild salmon, it seems to be beneficial in the short term, at least in terms of numbers, which in biology is called "rewilding".
However, in the long run, the harm is great.
This is because there is a genetic difference between farmed and wild.
To maximize profits, farmed Atlantic salmon have been genetically modified to grow faster, be larger, more resistant to disease and cold, and require less food.
If genetically modified salmon like this escapes into the wild and produces offspring in the wild, then the result is,It dilutes the genes of wild Atlantic salmon and further accelerates the extinction of wild Atlantic salmon.
Studies have shown that the survival rate of wild and farmed salmon offspring in nature is very low.
At the same time, farmed salmon tend to carry more parasites and pathogenic bacteria, and wild salmon are at risk of extinction.
Since the salmon population has declined dramatically, salmon fishing is no longer allowed in many areas of the region. Fishermen were thrilled to hear that salmon fishing could be paid and in their words:
"It's not just about the money, salmon fishing is exciting in itself!"
Many fishermen come for the bounty and are ready to make a fortune, and they have enough experience to distinguish between wild and farmed Atlantic salmon.
However, the reality is harsh, and the catch of farmed Atlantic salmon is very low.
第一周，只捕獲了400條，第二周250條，面對逃逸的2.7萬條，杯水車薪。It is highly likely that farmed salmon that are not caught have mixed into the ocean.
In fact, it's not the first time Mowi has had such a problem.
2018年，位於智利的養殖場就曾出逃69萬條鮭魚，2018年-2022年底，出逃數量超過160萬條。
At that time, Chile was known for its "irreparable environmental damage”為由，該公司在2018年被罰了670萬美元。
在挪威，除了這次出逃的，前兩個月還有6.5萬條幼魚失蹤，這一次，該公司或將再次面臨巨額罰款。
