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
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
