Aquaculture includes the production of seafood from hatchery fish and shellfish which are grown to market size in ponds, tanks, cages, or raceways.  Stock restoration or "enhancement" is a form of aquaculture in which hatchery fish and shellfish are released into the wild to rebuild wild populations or coastal habitats such as oyster reefs.

 

The reason why fish is such an important source of nutrition is that it both provides substances necessary for the human body and also reduces the risk of various diseases. For example, it has been revealed that when fish—which acts as a shield in terms of health with the omega-3 acid it contains—is consumed on a regular basis, it reduces the risk of heart disease and strengthens the immune system.

 

Fish meat also assists in the formation of healthy teeth and gums, benefits the complexion, makes the hair healthier and contributes to the fight against bacterial infection. It also plays an important role in the prevention of heart attacks as it beautifully regulates the level of cholesterol in the blood. It helps the body to break down and use starch and fats, making it stronger and more energetic. On the other hand, it also influences the functioning of mental activities. In the event that the vitamin D and other minerals contained in fish are not consumed in sufficient quantities, disorders such as rickets (bone weakness), gum disease, goitre and hyperthyroid may all arise.
