<strong>Shrimp</strong> farming systems vary greatly according to <strong>the</strong> intensity with which <strong>the</strong>y utilize resources (suchas l<strong>and</strong>, capital, labor, fuel, water, feed, <strong>and</strong> fertilizer). The economic desirability of different systems<strong>and</strong> <strong>the</strong>ir environmental impact depends to a large degree on <strong>the</strong> local scarcity or abundance of suchresources, <strong>and</strong> <strong>the</strong> way in which <strong>the</strong>y are managed under <strong>the</strong> farm operation. O<strong>the</strong>r specificcircumstances such as site conditions <strong>and</strong> <strong>the</strong> socioeconomic status of <strong>the</strong> operator will determine <strong>the</strong>relative desirability of different systems.High technology may produce high yields (measured in both production volumes <strong>and</strong> profitability), but<strong>the</strong>y require close monitoring <strong>and</strong> a great degree of knowledge on <strong>the</strong> part of <strong>the</strong> farmer. Whileintensive <strong>and</strong> superintensive shrimp farming technologies may be beneficial both by using little l<strong>and</strong><strong>and</strong> producing high output, <strong>the</strong>se technologies are in general more difficult to manage, <strong>and</strong> <strong>the</strong> risks arehigh.
