How sustainable are different kinds of Aquaculture?

Fish Farming
Fish farming is the most common type of aquaculture, it involves breeding and raising fish commonly for food in enclosures like ponds, rivers etc. Most of the fish we get are from fish farms which creates sustainable fish farming, but in the future with all the pollution and diseases spreading it could be unsustainable.

Land-based Aquaculture
Land-based aquaculture involves farming aquatic organisms on land in tanks with pools of water. Land based facilities can be quite expensive but is profitable and can be sustained.

Algaculture is a form of aquaculture which involves farming of the species, algae. One of the more known farmed algae are macroalgae or seaweed which can be used for commercial and industrial uses. Because of the size and specific requirements for the environment to be able for it to grow, it doesn’t look like Algaculture is very sustainable.

Intergrated Multitrophic Aquaculture
Intergrated multitrophic aquaculture uses a concept from nature, one species feeding in the waste by another species. IMTA involves farming one aquatic species to provide byproducts including waste which can be combined with other feed for fish or as a fertilizer. Scientists have studied ways to improve the productivity and environmental sustainability of aquaculture practices and came up with the idea of IMTA which makes it very sustainable.

  1. Good research here. I was just hoping you could at least compare land-based and ocean based aquaculture but you went beyond. The video mentions that the ocean pens can release diseases to wild populations so even thought the farmed fish may be sustainable, on a larger scale, it may not be so sustainable if it affects wild salmon.
