The Effect of Acid Solubilization Condition on The Yield of Calcium Extracted from Pacific White Shrimp (Litopenaeus vannamei) Shell PRACTICAL TRAINING REPORT This practical training report is submitted for the partial requirement for Bachelor Degree

Extracted Calcium from the shrimp shell can be utilized for the fortification because it is cheap but there are several factors that can influence the percent yield of shrimp shell such as pH, acid, temperature and time and this study used two parameters to find the suitable condition for the % extraction yield. Before it obtained % extraction yield, it used deproteinization to remove the protein and get the calcium from the Pacific White shrimp shell. Then, calcium extracted with HCl to get the mixture of calcium with acid from the shrimp shell. Percon et al (2003) reported that HCl didn’t give the good effect to the molecular weight in the demineralization of chitin but Poeloengasihhernawan (2009) stated it has high ability to remove ash and protein than acetic acid. After that, AAS was used to analyze the extracted calcium.

Effect of 17β-Estradiol on Feminization, Growth Rate and Survival Rate of Pasific White Shrimp (Litopenaeus vannamei, Boone 1931) Postlarvae

This experiment was conducted at National Broodstock Center for Shrimp and Mollusc Karangasem, Bali, Indonesia, where the Pacific white shrimp (L. vannamei) postlarvae also obtained. The sea water source was from coastal water of Lombok Strait and pumped to the sedimentation tank and left overnight. The water was desinfected with 30 ppm calcium hypochlorite for 16 hours without aeration, then full aeration was blown throughout the tank for 8 hours. Before use, the sea water was checked with o-Tolidine to make sure there was no chlorine left. When the o-Tolidine test result showed yellowish water, the sea water then de- chlorinated with sodium thiosulfate. After that, 5 ppm EDTA added as chelating agents of heavy metals in the water. The cotton filterbag (50 µm) was used to filter detritus, small organisms and turbid water while sea water being used.

Growth and survival of white shrimp post-larvae administered recombinant growth hormone by different immersion time

Growth and survival of white shrimp post-larvae administered recombinant growth hormone by different immersion time

This research was conducted to determine the optimum immersion time of recombinant giant grouper hormone (rElGH) at a dose of 15 mg/L that generates highest growth of white shrimp post-larvae at PL-2 phase. This research consisted of five treatments and threeplicates. The treatments were immersion time for 1, 2 and 3 hours. A total of 1,500 PL-2 shrimp were bath immersed in a plastic packing containing 1-L sea water, 15 mg/L rElGH and 0.01% bovine serumalbumin (BSA). Two kinds of control was performed, namely it was without any treatment (control), and immersed in water containing 0.01% BSA and total protein of Escherichia coli without rElGH (pCold control). PL were further maintained for 18 days in the aquarium, fed nauplii Artemia and flake commercial diet, 7 times feeding; 5 times by flake and 2 times by nauplii Artemia, at satiation. The results showed that the highest of the average biomass (36,289.87±1459,56 mg), specific growth (29,81±0,87 g%), and body length (20.08±0,42 mm) were obtained in 3 hours immersion treatment (p<0.05). Biomass of PL in 3 hours immersion treatment was approximately 66.0% higher compared to the control (21,872.19±2529,40 mg). Survival of shrimp in all treatment and control were similar (p>0.05). Thus, the bath immersion time of post-larvae for 3 hours in water containing 15 mg/L rElGH could be used to increase growth, and the application of this technology can be useful to increase aquaculture production.

The Evaluation of Earthworm (Pheretima sp) Enrichment on The Chemical Composition and Ovarian Development of Female Pacifik White Shrimp (Litopenaeus vannamei) Broodstock.

The results showed that gonad development stage both morfology and histology of C treatment was higher than B and D. The highest of broodstock that reach out for GDS IV was treatment A (28%), followed by treatment C (22.67%) and treatment D (17.33%). The observation of broodstock gonad chemical composition during maturation process from GDS II to GDS IV, showed that although gonad total lipid (TL) of treatments A, C and D increase, only treatment A and treatment C showed an increase in protein content, triacylgliseride, and polar lipid. These affected by betacaroten of both treatments were high enough, so be able to prevent the oxidation of gonad lipid mobilization process. In this study, the treatment that able to produce eggs are treatment A and C. Lipids were preferentially transferred to the eggs, which contained relatively high triacylgliseride and cholesterol levels. The chemical composition of eggs respectively were: protein content of eggs A. 1.87%, C. 12.94%; triacylgliseride content of eggs A. 0.73%, C. 0.70%; cholesterol content of eggs A. 0.62%, C. 0.49%; and beta-caroten content of eggs A. 20.62 mg/1000g, C. 18.2 mg/1000g. It can be concluded that earthworms (Pheretima sp) enriched by phospholipids, cholesterol and beta-carotene can be used as a white shrimp broodstock alternative feed for subtitute marine worms (Nereis sp).

Isolation and Characterization of Protein from Frigate Mackerel Fish Green Mussel and White Shrimp for Production of Isolate Allergen

Isolation and Characterization of Protein from Frigate Mackerel Fish Green Mussel and White Shrimp for Production of Isolate Allergen

Seafoods including fish, crustaceans and shellfish play an important role in human nutrition. However, it is also recognised as an important cause of food allergies, especially in coastal countries, including Indonesia. Treatments of these diseases still rely on avoiding the sources of the alergens, however it can also cause malnutrition which is also dangerous to health. To determine the specific food protein causing allergic reactions, cutie test was performed using isolate food protein. Until the present time, Indonesia still imports kits containing isolate proteins for food allergy diagnosis, therefore effort to locally produce the kit will reduce health cost for patients with allergic diseases. The objective of this study was to produce seafoods protein extract that is potential to be used as isolate of allergens for food allergy diagnosis. Two extract sarcoplasmic and myofibril protein were obtained from fish, shrimp and mussel by extraction in phosphate buffer with diference ionic strength Protein profile were then detected by means of sodium dodecyl polyacrylamide gel electrophoresis (SDS-PAGE). IgE binding pattern was analyzed by using ELISA and immunoblotting using sera from 20 respondents with histories of food allergy. The result of the study showed that samples of seafood extract protein consist of several protein with various molecular weight in the range about 14 to 143 kDa. The component were identified as tropomyosin (34-38 kDa), parvalbumin (~12 kDa), myosin light chain (~17.5 kDa) and arginin kinase (40 kDa) which are major allergens in seafoods. Further analysis with ELISA showed that the seafood protein extracts contained several IgE-binding proteins. Immunoblot of three extract samples from seafoods showed that components identified as allergens to each allergic subject have different molecular weight. The results demonstrated that crude extract could be directly used as isolate allergen for diagnostic test allergy (skin prick test) without isolating the major allergen components.

Nursery Culture Performance of Litopenaeus vannamei with Probiotics Addition and Different C/N Ratio under Laboratory Condition

Nursery Culture Performance of Litopenaeus vannamei with Probiotics Addition and Different C/N Ratio under Laboratory Condition

Addition of molasses in this study was aimed to stimulate the growth of heterotrophic bacteria which will be functioned to immobilize inorganic ammonia in the water. Furthermore, Avnimelech (1999) noted that manipulation of C:N ratio is a potential inorganic nitrogen control method for aquaculture systems. In contrast to other study (Samocha et al. 2007), addition of probiotics bacteria and molasses in this experiment apparently did not affect TAN and nitrite-nitrogen profile in cultured water. This might be related to the total N loading into the system, as higher biomass will result in a higher N organic loading. With this respect, the biomass of the treatments with molasses addition was higher than control (Table 3) which further followed by higher feed input and higher amount of waste loaded into the system. The similarity of TAN and nitrite-N profile amongst treatments showed that regardless of higher N organic loaded in treatments with molasses, there was an immobilization process of inorganic N that resulted in TAN and nitrite-N concentration as low as in control. The range of TAN, nitrite-nitrogen, nitrate- nitrogen and ammonia-nitrogen were respectively 0.46- 0.69, 0.22-0.54, 0.21-0.35, and 0.012-0.020 mg/l. Nevertheless, the level of inorganic nitrogen particularly ammonia observed in this study was in an optimal range aquaculture which must be less than 0.62 mg/l (Stickney 2005). A study by Samocha et al. (2007) showed that nursery culture of white shrimp in raceways with pressurized sand filter with molasses addition resulted in TAN and nitrite-nitrogen of 0.7 and 4.4 mg/l, respectively, which were higher than what has been observed in this experiment.

Harpeni et al., 2017 AI

Although survival rate of the shrimp fed with synbiotic supplementation was not significantly increase compared with control diet, this experimental diet (Diet D) could protect the shrimp with RPS value 53.48%. Other research reported RPS values of L. vannamei were 45.4 – 51.9 % while supplemented with probiotics and infected by V. harveyi (Liu et al., 2014). Arisa (2011) reported that synbiotic may enhance the resistance of white shrimp to V. harveyi. Further study also revealed that combination of probiotic and prebiotic from sweet potato in shrimp diets can significantly improve disease resistance by reducing mortality and stimulating immunity of the shrimp (Nurhayati et al., 2015). Meantime to death of the shrimp fed with Diet D could be longer than those consumed control diet. However, it seems that the Diet D only protect shrimp from bacterial attack. If the shrimp in Diet D still can be infected by V. harveyi, the using of Diet D will be not significantly different to the development of bacterial infection. Shrimps tend to survive longer in Diet D then those in control indicated that the diet was capable to block the bacterial attack at the beginning. However, the further development of bacterial infection has not been supported by significance of MTD. Therefore, mean time to death of the Die D was not significantly different than of the control diet. Mild infection and mostly degenerative hepatopancreas occurred in shrimp after the challenged test. Diet D has created less damage of hepatopancreas in shrimp. (Figure 3).

Competitiveness of Indonesian Shrimp Compare with Thailand Shrimp in Export Market

Competitiveness of Indonesian Shrimp Compare with Thailand Shrimp in Export Market

The Danish shrimp industry, a major processor and re-exporter, has been especially hit, and has witnessed a 17 percent drop in exports. The slowing economic growth in China has also cooled the country’s import demand. By contrast, US shrimp imports increased by 3 percent during the first half of the year, boosted by lower prices. Over the same period, deliveries to Japan rose by 2 percent, as retailers took advantage of the lower international prices to promote the product aggressively, a trend that is continuing in the second half of the year. As for exports, supply of vannamei (Pacific white shrimp) from India continued to be adequate during autumn, but the harvest of other species was poor. In Vietnam, the shrimp crop has been affected by disease, which has forced some Vietnamese processors to source vannamei from Thailand and India for export processing. In Thailand, a government scheme to stabilize the price of vannamei has been well-received by shrimp farmers resulting in the firming of shrimp prices during the third quarter [6].
