Fishes
Animals mainly aquatic, which can regulate their temperature from the environment, have breathing through gills, are also one of the main sources of food for humans for the protein properties they contain.
Fish farming is the rational cultivation of fish, through its control in terms of growth at different stages of development and reproduction, providing favorable environmental conditions for the growth and fattening of fish.
Advantage
Fish meat contains a protein amount higher than red meat, in addition to all the essential amino acids for a complete human diet. It also contains 30% less fat than red meat, therefore the controlled production of fish contributes to mitigate the environmental impacts and reduces fishing exploitation in rivers and lakes.
This results in the use of water surfaces and idle spaces, as well as the opportunity to learn a trade in people that help them improve their diet and quality of life.
Disadvantages
Biodiversity should be taken into account when cultivating fish since the cultivation of the same species, genetically deteriorate the species.
The space necessary for fish development must be taken into account because fish with less physical activity have less pleasant tastes to human taste.
Fish raised through fish farming require a diet that is usually based on fish meal, which is made up of smaller fish taken from the open sea. For this you need at least 11.9 kg of fish would to raise 453.59g of bluefin tuna. For what could generate imbalances between the production of food based on other fish.
