What is bad about fish farming?
Fish farms, or “aquafarms,” discharge waste, pesticides, and other chemicals directly into ecologically fragile coastal waters, destroying local ecosystems. Waste from the excessive number of fish can cause huge blankets of green slime on the water’s surface, depleting oxygen and killing much of the life in the water.
What are the problems with farmed salmon?
Waste, chemicals, disease, and parasites from the farms pass through the mesh and pollute the surrounding water and seabed. Especially harmful are the sea lice who attach to wild juvenile salmon on their migration out to sea.

Is aquaculture the new agriculture?
Placed in context to terrestrial animal agriculture, aquaculture is the new kid on the block , and has not had the benefit of gradual intensification over the last few centuries. This new industry paradigm is critical, as many suggest that a continued increase in aquaculture production is essential given the expected significant increase in global population in the coming decades ( Searchinger et al., 2019 ).
