Zhoushan fleet ... China accounts for a third of the world's consumption of seafood
The world's fisheries are in crisis. The United Nations' Food and Agriculture Organisation estimates 90 per cent of them have collapsed and China is the major player in their demise.
By a long way, China has the world's biggest deep sea fishing fleet that strip mines the world's oceans.
The Chinese government heavily subsidises the fleet in an attempt satisfy the country's insatiable appetite for seafood, which accounts for a third of world consumption.
In the port city of Zhoushan on China's east coast, 500 trawlers raced out to sea on the first day of the season.
Every season is harder than the last. The fleet have to head deeper into the ocean and stay for longer for a decent catch.
The Zhoushan fleet heading out to sea at the beginning of the fishing season.
The seas around China have virtually no fish left but the commercial fishing fleet is still huge.
With an estimated 200,000 boats, it accounts for nearly half of the world's fishing activity.
A dozen trawlers returned to Zhoushan with their first catch of the season — crab.
The hauls were good but well under half of previous years.
These days the smaller trawlers and boats mostly catch "trash fish" — tiny fish with little value, used as feed for animals and in aqua farms.
Like most others in Zhoushan, the only thing keeping Captain Lin and his crew afloat are government subsidies.
"The diesel fuel, fixing the boat would cost me 200,000 yuan ($40,000) the government subsides me more than 100,000 yuan ($20,000)," Captain Lin said.
The Chinese government has given $28 billion Australian dollars in subsidies over the last four years to its fishing fleet.
