Although it sounds like a paradox, mariculture is practiced onshore variously in [[fish tank|tank]]s, [[fish pond|pond]]s or [[raceway (aquaculture)|raceways]] which are supplied with [[seawater]].  The distinguishing traits of onshore mariculture are the use of seawater rather than fresh, and that food and nutrients are provided by the water column, not added artificially, a great savings in cost and preservation of the species' natural diet. Examples of onshore mariculture include the farming of [[algaculture|algae]] (including [[plankton]] and [[seaweed]]), [[Marine life|marine]] [[finfish]], and [[shellfish]] (like [[shrimp]] and [[oysters]]), in manmade saltwater ponds.
