Raising fish in cages in a lake in a relatively undeveloped environment. Urban aquaculture employs water-based systems, the most common, which mostly use cages and pens; land-based systems, which make use of ponds, tanks and raceways; recirculating systems are usually high control enclosed systems, [clarification needed] whereas irrigation is used for livestock fish.
Aquaculture expansion began receiving significant financial support from the government and multilateral organizations in the 1990s, as wild fish stocks decreased. [9]: 11 Marine fish cage use become large enough to be recorded in 1993. [16] Fish cage farming spread both in inland rivers and in coastal marine water.
Up until 2007, Chile experienced over 15 years of important growth in its salmon aquaculture, becoming the second largest salmon and trout producer after Norway. [1] [2] By 2006 Chile contributed with 38% of the world's salmon volume just behind Norway that produced 39% of it. [1]
