Abstract

Shrimp culture drives the national economy that are included in the program of industrialization of fisheries in the economic development programs of blue ( blue economy ). Shrimp farming in Lampung province remains a mainstay of the region as a foreign exchange earner . Kalianda , South Lampung is the center hatchery tiger shrimp (Penaeus monodon) and vannamei shrimp (Litopeneaeus vannamei ) the largest in Lampung. research conducted to observe the shrimp health management applied by growers of black tiger shrimp and vannamei shrimp in South Lampung and learn relationship between seed health management with quality seeds and tiger prawn shrimp vannamei shrimp health management dihasilkan. Data obtained by interview and the quality of shrimp seed obtained from observations in the laboratory with the observed light response, swimming activity, abnormality, gut contents, lipid droplets, the condition of the hepatopancreas and pigmentation. There are 22 hatchery were observed with the application of the value of health management in the high category for the third hatchery , hatchery medium category 6 and category bneih low at 13 homes. The quality of virus-free shrimp WSSV and IHHNV and the amount of bacteria in the body are normal and healthy shrimp was observed in the overall nursing bneih diamati. Relation between hatchery management application health and seed quality is reflected by the equation Y = 0,019X2 - 1,358X + 52.49 with the coefficient of determination ( R2 ) of 0.419. This relationship indicates that the quality of shrimp seed is determined by the health of hatchery management practices (r = 0.647). This study reinforces the importance of implementing health management hatchery known by farmers with biosecurity as a form of sustainable shrimp farming .

Abstract

Pacific white shrimpculture is having problems caused by bacteria infection. The cause of  bacteria infection is V. harveyi, it can decrease seed production. Pathogenicity of vibriosis can decrease with inhibition by other types of  bacteria. The aim of the research was to get competitor V.harveyi isolates through identification and challenge test in vitro and in vivo. The result of screening of bacterial isolates were obtained from cultivation supplement products to produced 4 pure isolates with different morphologically colonies and cells. There was one potential isolate could inhibits V. harveyi by inhibition test in vitro. Biochemical test from three different  laboratories were identified that Acinetobacter sp. as competitor to V. harveyi and it was not pathogenic to Pacific white shrimp. Challenge test Acinetobactersp. against V. harveyi on Pacific white shrimp larvae was conducted through three treatments, without given V.harveyi and Acinetobacter sp. As controls; treatment with given bacteria V.harveyi and treatment with given V. harveyi and Acinetobacter sp. The challenge test results showed that treatment with given of V.harveyi and Acinetobacter sp. may decreased V. harveyi density of 6.3x106CFU/mL to 7.5x103CFU/mL which could suspected to decrease pathogenicity of competition number of colonies.

Abstract

Water quality plays an important role in aquaponics system. Water chemistry parameter that may affect water quality is total organic carbon. Sources of carbon in the aquaponics system mainly derived from the decomposition of organic matter which derived from artificial feed and plant respiration. The research was conducted to study the reduction of total organic carbon concentration in the aquaponic system and the relation of abundance and diversity of phytoplankton. This research using different amount of ipomoea (Ipomoea aquatica) consist of 10, 20, and 30 rods and control treatments which use without ipomoea. The results showed that all of ipomoea treatments can reduce the amount of total organic carbon concentration in the aquaponics system. This research showed that nutrients cycle in the aquaponics system, especially total organic carbon dissolved in water is influenced by many factors such as plants, fish and primary productivity which determined by the plankton. Furthermore, a positive correlation occurred between total organic carbon concentration of the abundance and diversity of phytoplanktons (r = 0.5925; r = 0.6364). These results can be used for preliminary study of nutrient cycle model in aquaponic system.
