Acuaculture

 

It is the set of activities, techniques and knowledge of breeding aquatic plant and animal species

Advantage:

  1. It allows the production of food for human consumption in a controlled environment.
  2. The need to use fishing boats for the harvest of pests is avoided.
  3. It facilitates the production of usable raw material for different industries.
  4. It is possible to combine aquaculture with other forms of cultivation such as hydroponics (aquaponics), in order to create self-sustaining crop cycles. (Here, they use linked keywords to link some concepts with others on the page).
  5. Reduce the pressure on the fishing of endangered species.
  6. It improves the population’s diet and generates employment.

Disadvantages:

  1. If the aquaculture is done in a fixed environment (static fish cages), the little mobility of the fish accumulates waste at the bottom of the cages, which end up in the fish; and to prevent them from getting sick they are treated with antibiotics that end up in the human being.
  2. Fish raised in captivity are mainly predators, which generates a high demand for other fish obtained from ordinary fishing.
  3. The high density of fish in a region of reduced water (40kg / m3) generates a decrease in the level of oxygen in the area and diseases among fish.
  4. The flesh of fish raised in this way does not have the same quality as that of wild fish. For example, an excess of fat and omega 3 reduction have been found in salmon raised in captivity. (Source: https://www.nauticalnewstoday.com/tipos-acuicultura-marina/)
