Aquaculture and sustainbility

Q: How sustainable are different kinds of Aquaculture?

Every species’ sustainability depends on the species of fish and their current statuses, like their availability, and their current conditions, for example, are they in an endangered state. One concern is how wild animals (namely bears and eagles with other consumers) may obstruct fishery sustainability, as to them this is a vital food source to their survivability.

A good example would be how wild bears/eagles may eat wild salmon during the Salmon run (Salmon swim up to the upper banks of the river to spawn new offsprings). Also, there is the food chain — a crucial relation to species survival — everybody should be familiar about, on top of all the worries. If even one layer goes missing, it can massively affect ecosystem sustainability.

Also worth mentioning is the pollution to the ocean. Human to this point will still emit waste to the sea, namely chemical waste and most importantly, plastic. All kinds of animals can get into this mass, even to the point of extinction because of garbage. What they are inhaling is the hardly digestible materials. Also, they can even get killed just because they can get stuck inside those, making it even more dangerous then it should be.

Most species can ensure their chances of survival, but at one point, humans will need to do something against this problem. Fish farms are one of the useful ideas since we can profit from it and preserve the aquaculture at the same time so that the salmon can reproduce under safe conditions. But human wrongdoings, like overfishing, the destruction of natural habitats, and species extinction could break deal a massively negative effect on the balance.

Humans at times must remind themselves of this crucial fact; the ecosystem is a permanent part of nature; destruction or modification to any part of it can cause major unbalances of the aquaculture.
