Abstract :

Shrimp culture was essentially carried out since a few decades ago. Shrimp become an alternative choice as a fishery commodities, precisely when the introduction of vannamei shrimp in the continent of Asia in 1979. In America vannamei shrimp (Litopeneaus vannamei) better known as white shrimp. Since 1996, this shrimp has been known commercially, especially in mainland China and Taiwan Countries as a province of China State, then followed a lot of countries in Asia in 2001. In Indonesia, this shrimp started to go around the year 2000 and production of shrimp fry or seed was initiated in 2003 in a hatchery like Situbondo and Banyuwangi (East Java). This is the beginning of vannamei shrimp culture development in Indonesia. Field Work Practice have been carried out at PT. Surya Windu Kartika, Bomo Village, District Rogojampi, Banyuwangi regency, East Java Province. This activity was held on January 24 until February 24, 2011. Shrimp pond of "PT. Surya Windu Kartika" Banyuwangi is a business unit engaged in the fishery enlargement vannamei shrimp using biofloc system, In a sense language, biofloc derived from the word bio which means life, and floc which means clots. Biofloc is a collection of various microorganisms including bacteria, algae, fungi, protozoa, metazoans, rotifers, nematodes, and gastrotricha. flocs is formed by circulation coming from the aeration in the cultivation media. In principle, cultivation with biofloc system is developed bacterial communities in pond. In this case maintaining and growing dominance of bacteria in the pond is easier to implement than plankton because it does not depend on sunlight. So with this system is expected to provide earlier benefits biofloc as providers of food in pond as it can be applied in the afternoon and evening. The more floc formed in the pond the better because the floc - floc was able to break down the waste nitrogen in the waters of the proteins needed by the shrimp. With a high level of aeration the floc would remain in a state of suspended in the water. The content of protein and minerals are high on the floc is very favorable for shrimp. However, it still requires certain additional essential amino acids because of abortion is low, such as lysine, methionine, arginine, histidine, and tryptophan. Marketing of shrimp at the location of Field Work Practice are divided into two ways, first is an agreement between the "PT. Surya Windu Kartika" with a factory of "Surya Alam Abadi" in Banyuwangi. Shrimp have been harvested and meet the targets specified size will be purchased by the smelter. As for the shrimp harvest did not meet the standard size the plant will be sold to another buyer.
