It is the set of activities, techniques and knowledge of breeding aquatic plant and animal species
- It allows the production of food for human consumption in a controlled environment.
- The need to use fishing boats for the harvest of pests is avoided.
- It facilitates the production of usable raw material for different industries.
- 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).
- Reduce the pressure on the fishing of endangered species.
- It improves the population’s diet and generates employment.
- 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.
- Fish raised in captivity are mainly predators, which generates a high demand for other fish obtained from ordinary fishing.
- 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.
- 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/)
