Field Practice

White shrimp (Litopenaeus vannamei) culture has grown rapidly in Indonesia since  early 2000s. White shrimp have stronger resistance to WSSDV attacks, and are euryhaline. In it’s natural habitat, this shrimp was found in waters with a range of 0.5-40 ppt salinity. White shrimp grow optimally at 15-25 ppt salinity, even still suitable at 5 ppt salinity. This capability provides the opportunities to culture these commodities in inland water. White shrimp need inorganic elements or minerals for their living processes. Calcium is one of the main needs of shrimp that is closely related to the development and maintenance of skeletal systems and plays a role in some physiological processes of the body.The requirement for calcium in shrimp is increasing when it is cultivated in fresh water.This Internship aims to find out the technique of adding calcium carbonate (CaCO3) in feed, used for the white shrimp culture in fresh water. In this field practice, the addition of calcium carbonate in a level of 2% refers to the requirement of white shrimp for optimal growth. This was based on the calcium requirements of shrimp in the amount of 1-2%. The method was repelleting, by grinding feed and calcium using mortar and pestle, then filtered to get the smoothest part. Then mix calcium with 10 mL of water and mix it with pellets evenly. Then the mixture is air dried and mashed again and weighed according to the required dose of feed. The addition of calcium in the feed affects the growth of shrimp, because calcium is one of the most important anorganic mineral for the growth and development of exoskeleton, regulates blood clotting, heart rate, kidneys, nerves, the activity of several enzymes, and cell function

Shrimp culture has been developed during the last three decades and the production of farmed shrimp reached its peak. However, the shrimp production was decreased all over the World including in Asian Countries because of the mass mortality due to the outbreak of several diseases predominantly White Spot Syndrome Virus (WSSV) which caused extensive economic damage to the shrimp culture industry. Various Polyculture technologies of shrimp with shellfish, finfish or seaweeds have been implemented to reduce economic damages by mass mortality of shrimp. The present study was conducted with Tiger shrimp Penaeus monodon and Pacific white shrimp Litopenaeus vannamei through Polyculture operation to determine optimum stocking ratios for induction of best performance and highest production rates. Initially, the experiments were conducted with different ratios and combinations of stocking densities 1:1, 2:1 and 1:2 ratios of Penaeus monodon and Litopenaeus vannamei with control group feed with commercial feed, the other group certain Probiotic bacteria such as Bacillus licheniformis and Lactobacillus rhamnosus added in feed, the third group both the Probiotic bacteria and the addition of external Carbon source from sugarcane molasses in the form of Bioflocs for 100 days. To ascertain further interaction of ratios influence, 20:10, 20:12, 20:15 ratios of stocking and Monoculture experiments were conducted. In both the experiments the Survival rate, Final body weights, Weight Gain, Feed conversion ratio, Specific growth rates, Average daily growth rates, Protein efficiency ratio, and Productivity rates were significantly different (P<0.05) in all the different treatments both for P. monodon and L. vannamei. From the results obtained 20:10 ratio of P. monodon and L. vannamei was considered as the best ratio of stocking, which yielded the highest production rates in all the Control, Probiotic added and both Probiotic & Biofloc added groups. The results obtained in the present study clearly demonstrate that the rearing of taxonomically similar species with optimum stocking ratios seems to improve the efficiency of shrimp farming and substantially increasing the production rates. So, this polyculture of P. monodon and L. vannamei can be considered as an alternative approach towards the establishment of sustainable shrimp farming activity which will yield good economic returns.

This research aimed to evaluate the production performance of white shrimp Litopenaeus vannamei with super-intensive culture on different rearing densities. The research was conducted at PT. Dewi Laut Aquaculture, Cikelet, Garut, West Java. As many of 8 ponds were used and divided into 2 groups based on the stock density of shrimp, 550 ind/m2 and 650 ind/m2, and reared for 99 days. The results showed that super-intensive shrimp culture at the density of 550–650 ind/m2 potentially produced shrimp with average body weight ranged from 15.91–19.31 g, survival rate 62.67–87.95%, growth 0.16 to 0.20 g/day, FCR 1.35–1.66, and productivity reach 5.55–9.19 kg/m2. There were no significant differences between the two stocking densities in body weight, growth, and feed conversion performance, while ponds with higher rearing density had better survival and productivity than ponds with lower rearing density. L. vannamei cultured at a density of 650 ind/m2 produces the best performance and most feasible to be applied in super-intensive white shrimp cultivation.

The sesquiterpenoid methyl farnesoate (MF), a juvenile hormone (JH) analog, plays important roles in many physiological processes of crustaceans, such as morphogenesis, molting and reproduction. Juvenile hormone esterase-like (JHE-like) carboxylesterase (CXE) is a key enzyme in MF degradation, playing a significant role in regulating MF titer. However, its function is barely known in shrimp. In this study, a total of 21 JHE-like CXEs (LvCXEs) were characterized in Pacific white shrimp Litopenaeus vannamei, based on the full genome and multi-transcriptomic data. LvCXE has a conserved triplet catalytic site (Ser-Glu-His) and a characteristic GxSxG motif. Most LvCXEs were highly expressed in the hepatopancreas, which was the main site for MF degradation. LvCXEs containing a GESAG motif showed a specific expansion in the L. vannamei genome. Those GESAG-containing LvCXEs presented differential expressions at different larvae stages and different molting stages of L. vannamei, which suggested their potential functions in development and molting. Additionally, when the transcription level of CXEs was inhibited, it could lead to failed molt and death of L. vannamei. When we further detected the expression levels of the key ecdysone responsive transcription factors including LvE75, LvBr-C, LvHr3 and LvFtz-f1 after the CXE inhibitor was injected into L. vannamei, they all showed apparent down-regulation. These results suggested that the expansion of LvCXEs in the L. vannamei genome should contribute to the regulation of metamorphosis at larvae stages and frequent molting during the growth of L. vannamei.

Limbah cair tambak udang vaname (L. vannamei) merupakan hasil buangan dari proses budidaya yang umumnya langsung dibuang ke perairan umum. Limbah tersebut masih mengandung sejumlah unsur hara yang diperlukan untuk pertumbuhan organisme pada tingkatan trofik dibawahnya, salah satunya adalah mikroalga Chlorella sp. Namun, pada limbah tersebut masih ditemukan sejumlah organisme yang mengganggu pertumbuhan Chlorella sp. sehingga limbah harus disterilkan terlebih dahulu sebelum digunakan untuk menumbuhkan mikroalga tersebut. Tujuan dari penelitian ini adalah untuk mengetahui dosis limbah cair tambak udang vaname steril dalam produksi Chlorella sp. Penelitian ini menggunakan metode eksperimental dengan 4 perlakuan, yaitu A (dosis limbah 25%), B (dosis limbah 50%), C (dosis limbah 75%), dan D (dosis limbah 100%); masing-masing perlakuan diulang sebanyak 3 kali. Hasil penelitian menyatakan bahwa perlakuan D memberikan produksi Chlorella sp. tertinggi yang dapat dilihat dari kepadatan sel dan laju pertumbuhan spesifik pada saat puncak pertumbuhan, yaitu 2.833.333 sel/mL dan 0,472. Dari hasil penelitian ini dapat disimpulkan bahwa limbah cair tambak udang vaname steril dengan dosis 100% dapat digunakan untuk mengkultur Chlorella sp. skala laboratorium dengan menghasilkan produksi mikroalga tertinggi. Diharapkan limbah yang berasal dari hasil budidaya udang vaname dapat dimanfaatkan untuk mengkultur mikroalga sehingga mengurangi pencemaran yang terjadi di perairan umum sekitarnya. Liquid waste of vaname shrimp ponds (L. vannamei) is the result of waste from the cultivation process which is generally discharged directly into public waters. The waste still contains a number of nutrients needed for the growth of organisms at the lower trophic level, one of which is Chlorella sp. However, in these wastes there are still organisms that interfere with the growth of Chlorella sp. therefore the waste must be sterilized before using it to grow the microalgae. The purpose of this study was to determine the dose of liquid waste of sterile vaname shrimp ponds in the production of Chlorella sp. This study used an experimental method with 4 treatments, namely A (25% waste dose), B (50% waste dose), C (75% waste dose), and D (100% waste dose); each treatment was repeated 3 times. The results of the study stated that treatment D gave the production of Chlorella sp. the highest can be seen from cell density and specific growth rate at the peak of growth, which is 2,833,333 cells / mL and 0.472. The results of this study can be concluded that sterile liquid waste of vaname shrimp ponds with a dose of 100% can be used to culture Chlorella sp. laboratory scale by producing the highest microalgae production. It is expected that waste derived from vaname shrimp culture can be used to cultivate microalgae so as to reduce pollution in the surrounding public waters

The aquaculture industry in Indonesia has been growing rapidly and plays an important role in rural development and export earning. Penaeid shrimp culture in Indonesia has become a leading export earning in fisheries sector. The main constraint encountered with shrimp culture has always been associated with disease outbreaks, especially, caused by viral agents. The Pacific white shrimp (Litopenaeus vannamei) was unofficially introduced to Indonesia in 1999, and officially approved by Indonesian government in 2001. By the end of 2007, the Pacific white shrimp has been cultured in more than 17 provinces. The Taura Syndrome (TS) disease was detected in Indonesia in 2002, and the disease is currently found in at least 10 provinces. The Infectious Myonecrosis (IMN) is an emerging disease for L. vannamei in Indonesia, first detected in May-June 2006, causing significant mortalities in grow-out ponds. The IMN is characterized by an acute onset of gross signs: focal to extensive whitish necrotic areas in the striated muscle, especially on the distal abdominal segments and tail fan. White necrotic areas become reddened similar to the color of cooked shrimp. The outbreak resulted in elevated mortalities was initially associated with a chronic course of persistent low level mortalities. Up to date, IMN was detected in East Java, Bali, and West Nusa Tenggara provinces. This paper is a brief review of the epidemiological study of IMN disease of Pacific white shrimp in Indonesia: the status of outbreaks, surveillance, and disease diagnosis, and control measures.

Penaeid shrimp culture is a major contributor to foreign exchange earning in Indonesia. It has significant impact on economic development of fisheries sector, and leads to be one of prime mover to improve social prosperity. However, shrimp industry particularly black tiger shrimp (Penaeus monodon) has been facing unpredictable situation due to disease problem. The main constrain in correlation to the development of shrimp industry is disease outbreak, especially caused by viral agents. White Spot Syndrome Virus (WSSV) occurred in 1994, causing mass mortality of black tiger shrimp almost in all of the middle and western part of Indonesia. Due to the disease problem, it is estimated that in year 2000, more than 50% of shrimp pond were idle. Pacific white shrimp (Litopenaeus vannamei) or “udang vanamei” was introduced to Indonesia at the end of 1999, and released officially in July, 2001. Response of shrimp farmers to the shrimp rapidly accepted and distributed to many provinces in the country. At the end of 2006, distribution of white shrimp culture was encountered in more than 15 provinces. The seeds are mainly produced from hatcheries located in East Java and Lampung. The information of TSV in Indonesia was reported firstly from East Java at the end of 2002, without a clear history. Since then, survey of TSV distribution was conducted intensively in white shrimp production areas. Beside TSV, population of white shrimp coming to Indonesia also susceptible to White Spot Syndrome Virus (WSSV) and Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) infection. A survey with the aim to know significant viral diseases of white shrimp is needed to set up an alternative strategy to control them. The survey was conducted, firstly in the main production centers of white shrimp; and planned to be continued throughout the country. Samples collection, diagnostic method and data compiled in this study were collected from both active and passive surveillance. Diagnosis of viral diseases infecting white shrimp in this study was focused on TSV, WSSV, and IHHNV agents. Polymerase Chain Reaction (PCR) test has been used as a major diagnostic technique in this study. Progress report of the study showed that TSV spreading limited in controlled areas. The study proved that WSSV and IHHNV have been found in cultured white shrimp. All of the diseases mentioned above tend to be a significant constrain of future white shrimp industry in Indonesia, and special attention should be given in order to protect wide-spread of particular disease from infected to uninfected ones. Also, briefly current status of white shrimp culture development in the country will be discussed in this paper.
