Vaname shrimp is one type of shrimp that the people of Indonesia widely cultivate. However, there are several problems in the failure of vaname shrimp production, including poor water quality during the maintenance period, especially in ponds. Based on the selection of inclusion and exclusion criteria and quality assessment, it was found that the use of technology in cultivation activities will help streamline time, energy, and human resources so that decision-making can be made faster. The technology used is limited to water quality monitoring, disease monitoring, and EMS. The methods used to create IoT-based technology are hardware devices, software tools, function tests, and user tests. The smaller the error value, the more accurate the data obtained.

Whiteleg shrimp Penaeus vannamei (Boone, 1931) is one of the most popular and promising objects of world aquaculture. In this article possibilities and prospects of cultivating this species in Russia, the results of studies of temperature and salinity effects on the survival rate, growth, activity and food intake of white-footed shrimp were discussed. The critical values of temperature and salinity for this species have been determined. The most progressive for whiteleg shrimp cultivation are the southern regions of Russia, which have an extended sea coastline or a lot of hyperhaline or brackish waterbodies. Technologies combining commercial pond rearing with preliminary rearing of juveniles in RAS are recommended to use to increase the efficiency of cultivation.

This article attempts to provide a theoretical model of a small local mangrove economy. The structure of the model is based on observations from a qualitative field survey conducted in the Sunderbans region of West Bengal. The study showed that fishery is the primary source of income in this region. Agriculture is practised by many, but due to soil salinity, the sector, at best, provides sustenance for the family. Most of the other requirements are met from goods bought from outside. The role of the forest cover on shrimp cultivation is captured through the productivity effect, which increases the output per unit of labour and capital. In this structure, an optimum tariff on the timber industry is derived, and it is shown that the optimum tariff depends on the intensity of the productivity effect.

The failure of tiger shrimp (Penaeus monodon) farming could make farmers stop their cultivation activities. As an alternative, vannamei shrimp cultivation gives hope for productive, profitable, and sustainable cultivation. The development of shrimp farming in Tegal City is carried out through simple methods, intensive technology, and the use of Busmetik technology or mini-scale shrimp farming on plastic ponds. The high demand in the shrimp market continues to encourage farmers to increase their productivity by increasing stocking density. The purpose of this study is to determine the performance of vannamei shrimp cultivation which is cultivated intensively including yields, survival rate (SR), feed conversion ratio (FCR), and shrimp growth in Tegal City, Central Java Province. The research was conducted from July to October 2019. The research method used was a case study with 16 plots of ponds, and the average area of the pond was 1000 m². Based on the results of the calculation, it can be seen that the average yield is 1,603 kg per pond with a stocking density of 100 fish/m², a survival rate (SR) is 85.6%, a feed conversion ratio (FCR) is 1.41 and the shrimp growth is 0.16 grams per day. Economically, based on the Benefit-Cost Ratio (B/C ratio) of 1.46, vannamei shrimp cultivation in Tegal City is profitable so that shrimp farming can be carried out sustainably.

White feces syndrome (WFS) in shrimp cultivation ponds is characterized by the occurrence of shrimp with abnormal, white intestines (midguts) combined with large floating mats of white, shrimp fecal strings. The etiology for WFS is complex, similar to diarrhea in humans. EHP-WFS is a type of WFS characterized by massive quantities of spores from the microsporidian parasite Enterocytozoon hepatopenaei (EHP) together with mixed, unidentified bacteria in the shrimp hepatopancreas, midgut and fecal strings. However, WFS does not always develop in shrimp with severe EHP infections in controlled laboratory challenges. Further, in EHP-WFS outbreak ponds, some shrimp show white midguts (WG) while others in the same pond show grossly normal midguts (NG). We hypothesized that comparison of the microbial flora between WG and NG from the same EHP-WFS pond would reveal probable combinations of microbes significantly associated with EHP-WFS. To test this hypothesis, we selected a pond exhibiting a severe EHP-WFS outbreak in cultivated Penaeus vannamei and used a combination of microscopic and microbial profiling analyses to compare WG and NG samples. By histology, EHP plasmodia and spores were confirmed in the hepatopancreas (HP) and midgut of WG and NG shrimp, but pathological severity and spore quantity was higher in the WG shrimp. In addition, intestinal microbiomes in WG shrimp were less diverse and had higher abundance of bacteria from the genera Vibrio and Propionigenium. Propionigenium quantity in the HP of WG shrimp was significantly higher (P = 1.08e-5) than in NG shrimp (4,506 vs. 3 copies /100 ng DNA, respectively). These findings supported our hypothesis by revealing two candidate bacterial genera that should be tested in combination with EHP as a potential eukaryote-prokaryote pathobiome that causes EHP-WFS in P. vannamei.

Litopenaeus vannamei is a commercial shrimp that has high economic value. In recent years, the main commodity contributing to the aquaculture sector in Indonesia is vaname shrimp. Vaname shrimp cultivation aims to meet the increasing market demand. One of the factors that influence the success of vaname shrimp cultivation is the stocking density. This study aims to determine the growth and viability of PL-10 vaname shrimp (Litopenaeus vannamei) fry at different stocking densities. This study used a completely randomized design (CRD). There were 4 treatments, namely P1 with a stocking density of 75 heads / 40 liters, P2 with a stocking density of 150 heads / 40 liters, P3 with a stocking density of 225 heads / 40 liters, and P4 with a stocking density of 300 heads / 40 liters, respectively. 4 repetitions. The research data were analyzed using statistical analysis Univariate One Way Analysis of Variance at 5% level with a 95% confidence interval. The results showed that the highest daily growth rate was obtained in treatment P1 with an average value of 26.836 ± 0.745% / day, the highest daily length growth rate was obtained in treatment P1 with an average value of 6.719 ± 0.103% / day, the highest absolute weight growth was obtained at treatment P1. P1 treatment with an average value of 0.031 ± 0.027 gram, absolute length growth was obtained in treatment P1 with an average value of 23.025 ± 0.667 mm, the highest survival rate was obtained in treatment P2 with an average value of 96.333 ± 3.549%, but not different real with treatment P2 (93.333 ± 3.443%) and treatment P4 (92.417 ± 2.062). The conclusion of this study is that stocking density has a significant effect on the growth of vannamei shrimp which are being maintained at the PL-10 stage. The best stocking density in this study was P1 treatment (75 fish / 40 liters).

The attack of WSSV in Vannamei shrimp cultivation is still common. Shrimp quality improvement can be made through selection with the help of markers (marker-assisted choice). This study aimed to evaluate the DNA fragment profile of white shrimp that was resistant to WSSV disease. The analysis was performed using the PCR-RAPD method. WSSV challenged four groups of 100 Vannamei shrimp, then DNA was extracted from live and dead shrimp. The results showed that 2 of the 17 primers tested had high potential as markers, namely OP-09 and OPD-2. PCR products with OPC-09 primers had specific DNA bands measuring about 1.2 kb in all post-challenge WSSV resistant shrimp individuals. The amplification results using OPD-02 primers showed a particular band of DNA with a length of about 1.0 kb, with 60 % of the appearance in WSSV-resistant shrimp. In contrast, the WSSV-susceptible shrimp group did not have specific DNA fragments. Thus, the two RAPD primers had a high chance of being used in the selection with the help of markers to produce WSSV resistant shrimp.
