About a fifth of the world’s annual wild fish catch, amounting to about 18m tonnes of wild fish a year, is used to make fishmeal and fish oil, of which about 70% goes to fish farms
Among other environment impacts too. All kinds of fish farms dumps lage amounts of waste into the environment
For a world annual shrimp production [in fish farms] of around 5 million tons, 5.5 million tons of organic matter, 360,000 tons of nitrogen, and 125,000 tons of phosphorous are annually discharged to the environment
Informative memes, 10/10
I love how capitalism always manages to make things worse when it claims to make them better. People keep selling the grift of capitalism solving problems caused by capitalism.
How in the actual fuck is selfishness going to lower selfishness? Checkmate liberals
What’s the ROI? If 15% of wild caught fish are used to support fish farms that produce twice as much, it’s not as obviously a bad thing. There’d need to be another food source though.
Going to almost certainly be less than 1. Moving further up the food chain results in energy losses. Those fish are going to use energy for their own body and such
Moreover there’s high mortality rates inside of fish farms for fish themselves. From the linked earlier article
Fish mortality has more than quadrupled, from 3% in 2002 to about 13.5% in 2019, in Scottish salmon farms alone. About a fifth of these deaths are recorded as being due to sea lice infestations, but about two thirds are unaccounted for so the real mortality owing to sea lice – which feed on salmon skin and mucus, effectively eating the fish alive – could be much higher.

For sure, which is why I said “another food source would be needed.” I had in mind something like the wild-caught fish being processed into something useful as part of a more efficient food chain, e.g. combined with efficiently-farmed plant material.
Moreover there’s high mortality rates inside of fish farms for fish themselves.
I don’t have any context on the other pros and cons of fish farming, so definitely not arguing whether they’re a net positive or not.
Don’t really see how it’d make it any more efficient
In a new study out Monday in the journal Fish and Fisheries, researchers say that the vast majority of fishmeal is actually made up of fish deemed suitable for “direct human consumption.” […] Researchers say a whopping 90 percent of that catch is considered “food grade” and could be eaten directly
Not to mention there’s other effects of fish farms outside of just the overfishing part that I didn’t even list earlier. They’re actually a big player in mangrove deforestation, for instance
Conversion to aquaculture is the most prevalent driver of mangrove deforestation across the tropics over the last 50 years generating substantial carbon emissions. Preventing further aquaculture expansion within mangrove forest areas will be essential to achieve national emission reduction targets in mangrove-holding countries.

Or antibiotic usage
High frequencies of antibiotic-resistant bacteria have been reported in sites near aquaculture where antibiotics have been used, demonstrating that modified antibiotics in an aquaculture facility have a high potential to exert selective pressure and increase the frequency of antibiotic resistance in other environmental bacteria [40,41]. In the aquatic environment, 90% of aquatic bacteria show resistance to at least one antibiotic, and approximately 20% were multi antibiotic-resistant. […] An important and at the same time worrying aspect is that the antibiotics used in aquaculture include those used in human therapies, thus inducing resistance to these antibiotics
Being suitable for human consumption doesn’t mean it’s not also suitable for playing a role in a more efficient food chain
Have we tried farming sea lice? It’s probably just like shrimp.
Salmon Run
Booyah!
In other words, they’re Hell-bent on crashing the fish population lower and lower down the food chain.
They really should be trying to do lab grown fish meat. Would probably be easier than growing lab beef too. Would be perfect for Sushi too
If people could live on a grain of rice a day, someone would find a way to complain about it.
complain =/= near extinction events
Lay the blame on politicians denying climate change and large corporations with next to no obligation to operate in an environmentally friendly way. Laying the blame on average people living average lives, most of whom are just barely scraping by, is just defending the rich and powerful so that they can pass the buck on to the rest of us like they always do.
Going vegan can reduce your grocery bill by 30%
And we are all personally responsible for the animals we eat. Meat eating is a problem with our culture, not just a problem with capitalism, and we’re all responsible for changing the culture.

I understand the right half of the meme; sleeping with bad dreams about the thing. Wtf does the left side mean?
The original meme is the soldier protecting the kid from the knives - https://i.imgflip.com/2tzo2k.jpg?a477336
This version is implying that the soldier caption is doing nothing to protect the kid captionCheers. Thanks for that.
