When one designates Shrimps farm a special form of the aquaculture, with which shrimps or Shrimps for the human consumption are consulted. For the 1970er years productions of bred shrimps constantly increased, in order to satisfy the demand for such sea fruits in particular from the European Union, the USA and Japan. 2003 world-wide more than 1.6 million tons brought on such way produced crustaceans on the market. Their market value amounted to scarcely 9 billion USD.
75 per cent of the bred Shrimps in Asia are produced. The most important production countries are China and Thailand. Thailand is thereby the nation with the highest export portion. The remaining 25 per cent for the predominant part in Latin America is consulted, whereby the most important Latin American production country is Brazil. Almost all bred Shrimps belongs to the family of the Penaeidae.
Shrimps farms developed from a traditional agricultural production method, which existed in Southeast Asia for several centuries. Technical progress let become this breed method a global industry, since it permits an attitude of the crustaceans in increasing density. Breeding material is today world-wide sent away. Two kinds of crustaceans - Pacific White Shrimp and Giant tiger Prawn - constitute today about 80 per cent of all in Shrimps farms of consulted crustaceans. These industriellen Monokulturen are very susceptible to diseases, who led several times in the past already to a complete regional collapse of the crustacean populations consulted in aquacultures. The ecological problems, the repeated outbreak of diseases, connected with Shrimps farms, as well as increasing criticism both of groups of environmental protection and importing country for the late 1990er years changes in this branch of industry introduced. It partly accompanies with stricter adjustments in the producing countries. in addition 1999 were developed a program, which has the goal to develop nachhaltigere breed methods. Participants in this program are both authorities of individual countries, representatives of the producers and groups of environmental protection.
The artificial raising of crustaceans gives it in Asia as part of the traditional agricultural production methods. The use of brackish water ponds, the so-called tambaks leaves itself in Indonesia to in 15. Century retrace. In these in a small yardstick shrimps one consulted. This happened either as Monokultur or together with other kinds as for example the milk fish. Also rice fields were used, if in these during the dry period no could be cultivated to rice. Such traditional production ways were usual both in coastal regions and along Flussbetten. Mangrovengebiete were particularly gladly used for this production way, because shrimps naturally occurred here. Wild, yet not attained full growth shrimps were suspended in these ponds, which nourished themselves there of the naturally occurring water organisms. One harvested these shrimps, as soon as they had achieved the desired size. For the first time the beginning of the modern Shrimps farms can be attributed to the 1930er year, as Kuruma Shrimps (Penaeus japonicus) into Japan was artificially consulted. Into the 1960er years Shrimps farms in Japan had been already established as the smaller branch of industry. The break-through came however into the late 1960er and early 1970er years, when it was possible due to technical advancements to intensify the Shrimps breed. This accompanied with an increasing Marktnachfrage, so that Shrimps farms in all tropical and subtropical climate zones of the world began to be established. Came to meet the establishment of Shrimps farms in addition that the wild Shrimps catches diminished into the 1980er years, however a very broad demand existed.
