Aquaculture is growing animals and plants in a water environment. Aquaculture is a broad category that encompasses freshwater and saltwater marine systems. Some operations have systems that are “closed,” involving just fish production and “open,” involving other systems such as hydroponics. Aquaculture business has been growing by more than 60% in the last 10 years. It is the world’s fastest developing source of animal protein. Aquaculture is a neat way to understand biological cycles and how we can learn so much from nature by observing how wastes become another’s resource for food or nutrients.

In this section, you will learn about the different types of systems, how to create your own, and leave remembering the value of a closed loop system of which reuses another’s waste.

Fish are inhabitant of the oceans. His biggest predator is the human because of his exuberance to eat them in many forms. This fact and the industrial fishing methods that have the tendency to overfish a lot of specimens have led to the near extinction of some populations. The decline in number of fish has led to a worsen ecosystem in sea. Their are ambiguity of measures taken in some part of the Ocean. Also the development of a better regulation on fishery is time conquering.Thats why aquaculture can be a quick respons on the demand of fish while ecosystems in the sea have time to replenish themselves. 

Aquaculture has been set up in the open water sources such as the ocean. The next generation of aquaculture, by contrast, is land-based urban aquaculture situated in warehouses it uses a recirculating system for the water, with no discharge or antibiotics.
