FWIW, China also produces enormous (enormous) quantities of seafood from caged underwater oceanic farms. It's the future of fishing IMHO.
The rich, everywhere in the world, will continue to seek wild-caught though. (While they publicly rail against the poor eating wild-caught. Such is how the wheels turn.).
Yes, but I suspect they way they feed these fish farms (desired, commercially viable fish) is by catching large portions of other fish (which explains how they account for 44%), processing it (grinding, drying to pellets etc) and then selling it to the farmers.
It’s bad for the salmon (in terms of animal welfare) and it’s wrecking the local ecosystems. It’s not any sort of panacea.
We need to stop destroying ocean ecosystems, not just shift the damage around. Overfishing of wild stock, habitat destruction through bottom-trawling and intensive fish farming all need to be properly looked at.
The reality is that people are going to eat salmon. If you say all the ways of growing salmon are unacceptable people will just ignore you and go for the cheapest one. If you convince the government to tax salmon consumption the government will be removed. People really, really do not like to decrease consumption.
Fish is a major part of the diet there. People love it. They're not going to stop eating it. Fish is also good for you, and might be part of the reason why people in East Asia have some of the longest lifespans in the world.
The article only talks about visible fishing activity. But China operates many “dark fleets” where many unregistered boats sail along registered boats. They are fishing way more than the 44% that is being reported. These fleets will no doubt destroy ecosystems beyond repair.
Bottom trawling in particular seems horrendous. Here is Attenborough narrating about the horrors of it and how it affects the ocean floor: https://www.youtube.com/watch?v=tXp3jo_uGOQ
I wonder about engineering yourself a productive fishery instead of exploiting wild stocks.
Most of the ocean is practically a desert. The only productive places are near land, where deep water up wells and returns sunken nutrients back to the surface.
I'm sure we could study and engineer some sort of nutrient dumping and cycling scheme. I bet you could make vastly more food while leaving a lot of ocean alone.
A lot of their species interests can’t be fish farmed. Some can but it’s not exactly economical to shark farm or squid farm. Mussels, shrimp/prons, clams, salmon, some tuna, trout, and smaller fish can be farmed effectively.
While China dominates the fisheries, Japan is still whaling. The oceanic deserts are getting worse every day.
The recent David Attenborough documentary Ocean suggested that the Papahānaumokuākea Marine conservation area off the coast of Hawaii had contributed to abundant fishing stock outside the reserve. It was suggested that if we reserved 30% of the ocean, we would see a huge increase in fisheries the world over.
Another recent discovery is that although we've damaged our fisheries significantly, oceanic ecosystems apparently recover much faster than terrestrial ecosystems if left untouched, within several years.
I find it interesting how China is so keen to develop EVs as a way to get away from oil dependency, yet other areas of their economy aren't treated with the same urgency.
Doesn't seem that confusing, they import most of their hydrocarbons so its a domestic security risk if/when they invade Taiwan. The US navy can blockade oil tankers but they arent going to be chasing fishing vessels around the ocean trying to stop fishing.
The 44% mentioned in the data is actually composed of a large number of small family-run fishing boats, whose actual catch volumes are very low.In fact, China’s offshore catch (2.3 million tons in 2023, accounting for only ~10% of the global total and declining for three consecutive years) is far lower than its domestic aquaculture output (58.1 million tons).
Another year another DC China IUU "the worst" propaganda piece, except this time more stupid - already inflated esimate of PRC DWF fleet last year was 18000... now 32000 kek. It's hilarious to see PRC DWF inflation from 3000 in 2020 to 6000 to 18000 and now 32000 in 5 years. PRC ship building is incredible, but damn /s. PRC wild catch was like 12m in 2020... and 15m in 2024... but somehow catching that extra 3m required DWF to grow from 3000 to 32000. 950% / 29000 new boats to DWF fleet to catch... 25% / 3m tons more fish in 5 years. Truely lie flat behaviour from PRC fishermen.
First, something like 70-80% of PRC fish production is via domestic aquaculture.
Can clearly see from empty perimeter in the heat map PRC fishing largely stays clear of SKR, JP EEZ. Reason DC thinktank "report" try to play up 12m hours in SKR is likely that hotspot just south of SKR peninsula, aka disputed Socotra rock EEZ. And I surmise majority of JP 1.5m "hours" are over disputed Senkaku EEZ. 4.5m TW hours, obviously PRC considers TW waters part of her territorial/EEZ waters. About another 1m hours from SCS EEZ disputes. AKA 18/21m hours are basically DC think tank doing customary China bad funny stats from disputed maritime delimitations. Incidentally using said delimitations to extrapolate 3000k PRC distant fishing fleet into 30k+ in 5 years... somehow.
PRC has largest absolute DWF fleet size, but per capita she's underfishing, especially relative to TW, SKR, JP, who're at only 30-50% aquaculture. Spain and Russia also up there. Also fraction of SKR/TW subsidies per capita, about on par with JP. Of course you don't see DC thinktanks hitpieces telling these actors to kill their DWF fishing industries. For PRC's DWF fleet to match other top DWF fleet's capita fishing efforts, she would have to fish something like 3-9x+ more. Unless one thinks PRC fishermen and citizens shouldn't have the same opportunities or access to seafood. Ecuador & Peru, two countries with ~1/30th population of China, together captures about about ~1/2 of China, who also has 1/2 the EEZ of these countries, which incidentally means China has to fish more in international waters.
The only reason PRC IUU fishing got media play / propaganda push in the last few years is US wanted to beef up influence of pacific nations playing up PRC IUU fishing so they can drive the issue to forward deploy coast guard and build influence. It's geopolitical lawfare, and it's unlikely to do anything substantive because any agreement by PRC on curtailing distant fishing would be on per capita basis which would first involve everyone else (JP,SKR,TW etc) to essentially kill their entire DWF industry before PRC would even need to make any cuts.
Again, let's stress how absolutely batshit stupid these new numbers are:
SKR, ~500-700 DWF fleet, 300-400k metric tons per year.
JP ~1200-1500 DWF fleet, 600-900k metric tons per year.
TW ~1000 DWF fleet, 400-600k metric tons per year.
AVG 400-800 tons per ship.
PRC... 32000 DWF fleet, 3000k metric tons per year.
AVG 90 tons per ship.
Or... avg 400-800 tons per ship
PRC ~3750-7500 DWF fleet
PRC official report is like ~2700 in ~2020, add 25% for 25% by 2025 increase catch and you get ~3400. It's underestimation (and while PRC wanted to cap to 3000 in last 5 year plan), but it's underestimate by 100s, not over estimation by 10000s. Like tag on highest maritime militia estimates of ~10k, and it's still almost ~20k over.
E: or just look at estimates of global seafood market growth... ~5% CAGR, ~+50B over past 5 years. Like 35B of that from PRC aquaculture growth. What's the 29000 new DWF doing? Global DWF size for major fishing nations is like 6000... so PRC adds... 500% that and somehow global fishing market grows by... 30%. US thinktank innumeracy.
I mean pollution is bad, regardless of who does it? China is also fairly unique with the brazenness that her (flagged) vessels violate other EEZ waters to fish.
Fwiw the United States is doing a lot of effective work to combat this. A lot of countries have large EEZs covering a lot of the pacific but have no navy to police it with. The last coast guard commandant, Adm. Fagan, intorduced bilateral law enforcement agreements with multiple pacific island countries (https://en.wikipedia.org/wiki/U.S._Bilateral_Maritime_Law_En...) to police their EEZs with US coast guard vessels (the fig leaf used to be you'd have one foreign captain and deputize the whole ship, but now there are 'no rider' agreements that basically is 'change the flag, don't have to change anyone aboard'). China is deterred, the fish are saved, sovereignty for independent states is safeguarded, and the United States secures the world again.
Anyway, she was yet another casualty of MAGA! She was forced out on Trump's first day because of DEI, presumably because she was the first woman to run a service. For now, the program still survives, both funding and personnel-wise (modulo a few hull-days spent running around the southern border and the... uh, gulf of ~america~ mexico?), but man.
To learn more, I'd listen to war on the rocks! They have great guests.
My grandfather lived in a time when commercial hunting was outlawed.
I worry that I live in a time when commercial fishing is not sufficiently regulated so that rather than being outlawed, it will simply become infeasible, with the attendant knock-on affects of countries which depend on the oceans for a significant portion of their protein.
There are now a greater tonnage of ships in the ocean than bony fish:
One particular fishing tactic by Chinese fisherboats is horrendous.
They will approach a protected ecosystem, which is thriving with fish like that of the galapagos islands, for example. They will hang out right at the limit of the maritime nautical border with the native country.
Then they will shut down naval GPS transponders (disabling of AIS - Automatic Identification System) and during the night, all at the same time, cross into the country's maritime space and quickly get out before its caught by the local patrols. [1][2]
This happens a lot with smaller countries which cannot fight back.
There are other techniques that haven't been yet discussed, like, altering vessel measurements (Changing draft and length to obscure activity, e.g., during transshipment or EEZ entry) , and meeting with refrigerated cargo ships to transfer catch which is likely illegal.
These are the only ways they can sustain a 44% of fishing worldwide. If they did this in their home turf, their waters would be empty of life
When they say global warming is killing fishing population, and avoid talking about the real problem - a huge ghost fleet using environmental devastating methods of fishing all over the planet
One massive problem with data collection on fishing, is that the world is absolutely littered with outright fake AIS data, where the vast majority are registered as Chinese vessels. Anyone can purchase a AIS transmitter, and spoof the data. Some areas are much more affected - especially out in the middle of the pacific ocean, and the Indian sea. Some areas there can have almost 100% spoofed AIS data. So a lot of work goes toward filtering these out.
When working on this kind of analysis, you have a bunch of data sources: AIS, VMS, LRIT, which are either land or satellite borne. Other than these, you have SAR, Optical, NRD (navigation radar detectors), and some other - but with these, you obviously need to have some classification and correlation system. AIS is by far the most common source, and it is also the one that is easiest to manipulate.
Vessels can simply turn off their AIS transponders, while out at sea. And it can easily be spoofed. But a lot of the garbage AIS data is really just that, random garbage. Just some random MMSI attached to a Chinese flag, and a completely random sailing pattern. These are relatively easy to filter out, but often times they share the MMSI with actual vessels - many which are indeed Chinese vessels.
So no one here seems willing to address the underlying problem. Population ! The Earth needs a break from the constant beating it takes from irresponsible Humans. "IF" possibly the Human race on this planet could be reduced significantly, the overall condition of life would be greatly improved. This is the Most Important Issue. NO ONE WILL GIVE THIS THE PROPER ATTENTION THIS PROBLEM NEEDS.

Five years ago, China was assessed to have 17,000.

I'm sure we could study and engineer some sort of nutrient dumping and cycling scheme. I bet you could make vastly more food while leaving a lot of ocean alone.
There are places famous for it, and there are other places like French Polynesia where they use existing atols as places to do it.
It's not easy, but it can be very productive.

There was a story [0] that ran in the New Yorker a year ago that detailed how North Koreans are sent to Chinese seafood plants in forced labor.

it exists at country level too, not just individual level.
