As average consumers, we are well aware that fishing does not limit itself to benevolent fisherwomen/men equipped with fishing rods. We know that fishing is more than often carried out by large ships equipped with gigantic nets which allow fish to be scooped out of the water by the ton. However, it is interesting to notice that the reality of the fishing industry is far form being widely known and that fishing does not necessarily mean “catching fish”. | As average consumers, we are well aware that fishing does not limit itself to benevolent fisherwomen/men equipped with fishing rods.

The cultivation of these species is pursued either in a natural settings such as seas or lakes for instance, or in human-built pools which can either be dug in the ground or built and set on land. | The cultivation of these species is pursued either in a natural settings such as seas or lakes for instance, or in human-built pools which can either be dug in the ground or built and set on land. | ||
One reason to explain the lack of awareness in the western world towards the use of Aquaculture in the world is the fact that Asia represents nearly 90%<ref>Estimated at 89.4% in 2016</ref> of the industry, with China alone producing 61.5%. Other large producers include: India (7%), Indonesia (6%), Viet Nam (4.5%), Egypt (1.7%) and Norway (1.7%). | |||

How to explain the exponential growth of the sector? What Aquaculture allows is to make use of land where the conditions of the soil and the chemical properties of the water make the land inhospitable for conventional food grain crops or pasture. This applies to, either polluted, over-farmed or desertic terrains. | |||
== So what is Capture fishery? == | |||
Close to 90% of the world's capture fishery come from oceans and seas, as opposed to inland waters. Most marine fisheries are based near the coast. This is not only because harvesting from relatively shallow waters is easier than in the open ocean, but also because fish are much more abundant near the coastal shelf, due to the abundance of nutrients available there from coastal upwelling and land runoff. But productive wild fisheries also exist in open oceans. | |||

Regulations to prevent over-fishing as well as ecological variations however also constantly redefine the landscape of capture Fishery. The production of Anchovetas<ref name=anchoveta /> in Peru, for instance, was 3 times more developed than any other species before 2014. Due to the impact of Hurricane El Niño as well as strong regulations, the production was divided by 3 in 3 years, putting Anchovetas on the second step of the podium in 2016. | Regulations to prevent over-fishing as well as ecological variations however also constantly redefine the landscape of capture Fishery.
