aquaculture

The cultivation of seafood under controlled conditions

aquaculture cons

antibiotic overuse, destroy coastal ecosystems spread disease, or introduce invasive species if the aquaculture is in estuaries

The density of fish in aquaculture can lead to increases in

disease incidences, which can be transmitted to wild fish.

aquaculture increases

food supplies and protein sources, increasing overall food security

Aquaculture has expanded because

it is highly efficient, requires only small areas of water, and requires little fuel.

helps to reduce

overfishing of wild fish and the unintended catch of other organisms called bycatch

we use aquaculture to

raise seafood

The farming of fish such as salmon at aquaculture facilities poses a threat to marine ecosystems because

the farmed fish can escape and outcompete wild fish for food and territory

Aquaculture can contaminate

wastewater, and fish that escape may compete or breed with wild fish
