For seafood lovers,

Salmon is an indispensable delicacy on the table.
But recently, Australia's salmon has suffered a disaster,
Many Australian salmon lovers may have a lonely mouth for a while...
1, 1.35 million salmon died violently, and the "ten thousand fish pit" caused a foul odor
Recently, the residents of Triabunna on the east coast of Tasmania have been miserable because of a "million fish pits"!
According to ABC News:

To dispose of millions of dead fish, salmon farmers in Tasmania have dug a large pit for them to bury thousands of tons of salmon carcasses.
But because of the sheer number of dead fish – more than 4,000 tonnes – and the long waiting time for them to be processed , the bodies have begun to decay, attracting flies and continuing to emit a foul odor.
Residents near Triabunna have been plagued by this putrid smell mixed with fishy smells for weeks, complaining bitterly and even organizing street protests.
In fact, the Tasmanian Salmon (Salmon) Farmers Association TSGA has submitted several ways to deal with dead fish to the Environmental Protection Agency (EPA), but they have all been "shot".
Method 1: Offshore dumping method
Reason for denial: Under the Federal Environmental Protection Act, a permit is required to dump a large number of dead fish carcasses at sea, and the dead carrion is accompanied by a large number of bacteria, which can adversely affect the marine environment.
Method two: composting method
The reason for the denial: it stinks, it attracts flies, and because of the biosecurity protection law, there is a great risk of contamination by doing so.
Method 3: Incineration method
Reasons for denial: The waiting time is too long: 20 weeks; 4,000 tonnes of dead fish requires an oversized incinerator, which costs too much: around $2 million.
However, the only approved "fish pit burial law" has also received strong protests from the public and may not be able to continue.
Where should these thousands of tons of dead fish go, TSGA is still looking for a solution...
So, what exactly caused this salmon farming disaster?
In fact, a long time ago, the greed of farmers laid hidden dangers for this "natural disaster and man-made disaster"...
2. Crowded fish pond + wild "uninvited guest"
Between October last year and May this year, a total of 1.35 million salmon have died in Port Macquarie;
On its worst day, petuna fisheries lost nearly 55,000 fish and nearly $3 million in a single day.
This has caused a huge shock to the entire Port Macquarie salmon farming industry, with australia's three major fisheries: Tassal, Huon and Petuna all losing heavily.
But in the final analysis, it is still the "greed" of the merchants who are at work...
In recent years, as Australian salmon has gradually opened up overseas markets, Tasmanian salmon farmers have tasted the sweetness of "sudden wealth" overnight, and the value of Tasmanian salmon farming has exceeded 800 million Australian dollars.
Due to the increasing demand for salmon, farmers have also expanded the scale of farming, but many farmers have doubled their input in fry, but in order to save costs, they have not expanded the size of the pond.
As the fry grow larger and larger, the ponds become more and more crowded,
Not only is the living space getting smaller and smaller, but even the oxygen is getting less and less...
As early as last summer, the relevant departments issued a warning: the dissolved oxygen content in the breeding ponds in Port Macquarie is already too low, coupled with hot weather, the fish in the breeding ponds are easy to die, and farmers must be careful!
But it costs money to expand the breeding pond, and it also costs money to buy an oxygen injector.
What's the point of dying dozens of fish, making money is the last word!
In this way, farmers put this warning behind and continued to borrow the salmon boom to frantically fish for gold!
But the weather is unpredictable, and a group of wild "uninvited guests" have shattered their dreams of getting rich...
In May 2018, a group of sardines from the open sea arrived at Port Macquarie,
This wild population carries a deadly virus, POMV.
Due to the crowded fish ponds, extremely low oxygen levels, and high summer water temperatures, the POMV virus has wreaked havoc in the fishing grounds of Port Macquarie, sweeping through all the fish ponds at an alarming rate, causing millions of salmon deaths.
Rise and fall, just in the middle of this night.
The arrival of the POMV virus has reduced Port Macquarie's fish production by a sharp 21%, from 12,000 tonnes to 9,500 tonnes!
Farmers who have suffered terrible losses do not wake up until they see thousands of tons of dead fish floating on the water, but it is too late...
At last
Eat a trench, grow a wisdom. With this bitter lesson, farmers should no longer ignore the long-term hidden dangers for the sake of small profits...
But it is the residents near the fishing grounds who have endured the stench for several months in a row, and these farmers are really harmful and harmful to themselves!
