When the climate is warming, fish stocks can collapse.
That happened to a number of species around the world, including the endangered Japanese bluefin tuna, the endangered Atlantic salmon and the endangered sea bass.
But that didn’t happen in the US, where the global fishing industry thrived thanks to cheap cheap fish that were caught from the ocean.
When the oceans became too cold to catch fish, they were simply killed off, and fish stocks in the United States were virtually gone.
That changed in 2015 when the Obama administration began to cut back on fish stocks, but it also had an impact on the fisheries of the United Kingdom.
It has now set the target of halving the number of fish caught in the UK’s fishing fleet by 2020, from 10% to 3%.
But the government has announced plans to cut the number in the same timeframe.
The fish industry in the country was in crisis when it all started.
The UK was the world’s biggest fish consumer in 2011, but by 2015, it was losing about 15% of its fish catch.
In 2014, there were more than 400,000 tonnes of fish in the ocean, compared to around 1.5 million tonnes in 2015.
But the UK is not alone in having a food security crisis.
Other countries have experienced similar problems in the last few decades.
In 2016, the World Bank said that global fish stocks were at risk of “an unsustainable decline”.
In Europe, the European Commission recently announced a new target of limiting global fishing to between 1% and 4% of global catch by 2050.
But there is hope for the UK.
A 2015 study by the University of Oxford found that a reduction of the UK fishing fleet of between 10% and 15% would save the country £1.5bn per year.
A reduction in the number, and the amount of fish, can also make a big difference to the health of the country’s fish stocks.
In Europe’s coastal waters, the British government has set a target to catch between one and two million tonnes of Atlantic salmon by 2020.
The study found that the fish could save up to £2.8bn per annum.
But in the Atlantic, that amount is only about $4bn.
“I think it’s a very important point to be able to say that there is an economic argument to the case for cutting back on the fishing,” says Professor Andrew MacKinnon, the lead author of the study.
“That is, if you can get the UK fishery back on track and if you’re looking at reducing fishing in the North Sea and the Baltic Sea, the economic benefit will be quite significant.”
If the UK were to halve its fishing, the impact on Atlantic salmon stocks would be quite large.
“The Atlantic salmon population is very resilient,” says MacKampons research.
“There’s a lot of resilience there.”
MacKamps research found that there are more Atlantic salmon in the sea than in the rivers and streams that feed the fish, and that if fishing were to be restricted in one of these streams, the salmon could disappear from the waters.
That could mean that the salmon population in the Baltic would be drastically reduced.
“We would see a big reduction in their abundance,” says Andrew Mackampons.
The problem is that the UK has had a very successful fishery for many decades.
It is one of the largest commercial fishing areas in the world.
That’s helped to sustain the fishing industry for decades, even though it is also one of Europe’s poorest countries.
The number of UK-fished fish in its oceans is much higher than the average for the EU, but the UK was a net exporter of fish during the 2000s.
“This was largely because of the cheap fishing that the British had been able to do and it was just a way to survive,” says Michael Berenbaum, director of the Marine Biological Laboratory in Plymouth, UK.
The reason the UK fish stocks are so healthy is because the UK also exports a lot more fish than it imports.
“It’s the UK that has a huge export economy,” says Berenba.
“They have to export a lot, so we import a lot.”
But the US has a much more difficult time catching fish because of its high price of oil.
“With oil prices rising, we’re exporting a lot less than we imported a lot earlier,” says Dr Andrew Schreiner, an oceanographer at the University
