  • Effect of Spirulina (Arthrospira platensis) Powder on The Physico-chemical
           and Sensory Characterization of Dry Noodle

    • Authors: Dinda Ersyah, Abdul Aziz Jaziri, Dwi Setijawati
      Pages: 277 - 288
      Abstract: Dry noodles are a staple food item among Asian population. Generally, it contains a low-fat and a high-carbohydrate level, however it lacks other nutrients, such as protein and dietary fiber. The addition of spirulina into dry noodles may increase both protein and dietary fiber. The aim of this study was to determine the effect of spirulina fortified in the dry noodle on physico-chemical and sensory properties. The method used in this study was experimental with a completely randomized design (CRD) using 4 replications. The spirulina powders added into dry noodles were 0%, 4%, 4.5%, 5%, 5.5%, 6% and 6.5%. The results showed the addition of spirulina in dry noodles had a significant effect (p<0.05) on nutritional values, such as protein, fat, ash, carbohydrate and dietary fiber. In addition, physical properties of fortified noodles, including cooking loss, elongation and tensile strength were also significant differences. For sensory attributes, noodles fortified with different concentrations of spirulina showed significant effects in appearance, aroma, color, taste and texture. A selected dry noodle fortified with 6% of spirulina based on the physico-chemical and sensory characterization. The fortified dry noodle can contribute to improving nutritional profile that may be beneficial on health.

           Protein Content of Osphronemus gouramy Juvenile

    • Authors: Putri Dista Ananda, Safrida Safrida, Khairil Khairil, Hasanuddin Hasanuddin , Asiah M.D.
      Pages: 289 - 297
      Abstract: Gouramy (Osphronemus gouramy Lac.) is one of the original fish from Indonesia that lives in fresh water and has high economic value because of its dense texture, high nutrition, and delicious taste so that it is widely favored by Indonesians. The results of juvenile cultivation activities have not been going well so far, this is because the growth of gouramy’s juvenile is slower than the growth of other freshwater fish’s juvenile. One alternative that can increase the growth and protein content of gouramy juvenile is to utilize of the availability of lamtoro seeds. The purpose of this study was to determine the effect of feeding lamtoro seed fermentation on growth and protein content of gouramy’s juvenile. This study used experimental method with a completely randomized design (CRD with 6 treatments and 4 replications). Data were analyzed using Analysis of Variance Test (ANOVA) and further test in the form of Honest Significant Difference (Tukey HSD Test) at the 95% confidence level. The results showed that P3 with the addition of fermented lamtoro seed flour 40% can increase the growth and protein content of gouramy juvenile. The conclusion of this study was lamtoro seed fermented feed has effect in increasing growth and protein content of gouramy’s juvenile.

  • Combination of Nigella sativa and Phyllanthus niruri as An Immunostimulant
           for The Prevention of White Spot Disease in Litopenaeus vannamei

    • Authors: Wida Lesmanawati, Wasmen Manalu, Min Rahminiwati, Muhammad Agus Suprayudi, Sri Nuryati
      Pages: 306 - 316
      Abstract: Pacific whiteleg shrimp (Litopenaeus vannamei) is a very important commodity, which accounts for almost 70% of the total world shrimp production. However, this production is still threatened by disease attacks, one of which is caused by white spot disease (WSD). Herbs are widely used as immunostimulants as an effort to prevent diseases. Black cumin (Nigella sativa) and stone breaker (Phyllanthus niruri) have long been known as excellent immunostimulants in human. This study aimed to evaluate the potential of N. sativa and its combination with P. niruri as an immunostimulant in L. vannamei for preventing WSD. Tested shrimp (±3.0 g) were treated by N. sativa (N), P. niruri (P) and the combination of both (1N:1P, 2/3N:1/3P, 3/4N:1/4P, 1/3N:2/3, 3/5N:2/5P, 1/4N: 3/4P, 2/5N:3/5P) through feed for 28 days. They were then infected by white spot syndrome virus (WSSV) and observed for 7 days. The parameters observed included immune response and production performance. N. sativa was able to reduce the mortality of test shrimp infected with WSSV, with an RPS value of 71%. N. sativa can be combined with P. niruri in the right composition (1/2N:1/2P and 2/3N:1/3P), while the other combinations are antagonistic. The administration of the best treatments in this study, relatively did not affect the value of total hemocyte count, phenoloxidase activity, respiratory burst activity, hemolymph clotting time and production performance of tested shrimp.

      Pages: 327 - 334
      Abstract: This study was designed to investigate for the first time in the region of Ouargla, Algeria, the events and timing of the embryonic development of African catfish, C. gariepinus (Burchell, 1822). The embryonic development was carefully monitored using a binocular magnifier 10 and 20 lenses that reveal details on live specimens from fertilization to the first take of food. The offensive and foul odor continues to be the characteristic smell of the hatching stage. Pigmentation and continuous spread of cephalo-caudal melanophore in fry hatched on the first day. The barely hatched larvae are photo-phobic. The yellow reserve is reduced and leads to the ability to swim easily, and the majority starts feeding on the fourth day. The vitellin reserve is significantly reduced, allowing the larvae to feed exogenously. The events observed in our opinion demonstrate the presence of two exceptionally critical parameters: the use of a high-quality diet and the guarantee of a clean and quality source of water, meeting the standards of aquaculture farming.

      Abstract: Problems in cultivating milkfish are disease outbreaks and the high cost of feed. Therefore, a breakthrough is needed to overcome this problem by adding medicinal plants, namely aloe vera, to the feed. This study aims at determining the effect of adding aloe vera to artificial feed on the blood cell profile and growth of milkfish seed. The research method used was a complete randomized design with 4 (four) treatments and 3 (three) replications. The treatments on the test feed used were: A, (giving aloe vera as much as 0 g/kg feed), B (giving aloe vera as much as 5 g/kg feed), C (giving aloe vera as much as 10 g/kg feed), and D (giving aloe vera as much as 15 g/kg feed). The results showed that blood glucose values were still within the normal range. The lowest value in treatment was A, which was 42 mg/dL, and the highest in treatment was D, which was 66 mg/dL. The lowest Hb value was found in treatment A (5.1 g/dL), and the highest was 7.2 g/dL, found in treatment D. The highest average growth rate was obtained in treatment D with increasing biomass of 3.81g. While the lowest growth was obtained in treatment A which resulted in average growth of 2.06g. Water quality during the study was suitable for milkfish rearing media, namely temperature of 27 - 31°C, pH of 7.2 -,7,8, and salinity of 25 - 27 ppt.

  • Characterization of Salt Quality from Artemia (Artemia franciscana)
           Cultured Water with Dunaliella salina as Natural Feed

    • Authors: Himna Sayyyidatul Islamiyah, Mochammad Amin Alamsjah, Laksmi Sulmartiwi
      Pages: 352 - 358
      Abstract: The high demand for domestic salt cannot be achieved by local salt production from traditional salt and PT. Garam fluctuates every year. In addition, the quality of traditional salt is still low. This causes the need for domestic salt consumption to be met by imported salt. Therefore, it is necessary to have an alternative to meet the domestic salt demand, namely the revitalization of salt ponds for the development of mass Artemia cultivation that produces both Artemia production and biomass and produces salt in one location. In its natural habitat, Artemia uses microalgae as its main food source. The quality of microalgae feeds greatly determines the production of Artemia franciscana. The availability of nutrients is a factor that determines the rate of growth, so the amount and quality of feed are the main factors to meet the nutritional content for optimal development. Therefore, the salt production in this study used saltwater cultured Artemia with Dunaliella salina as a natural feed with a water age of 3rd,7th, and 14th days. This study aimed to determine the best age of Artemia water cultured with Dunaliella salina as a natural feed in salt production. The results showed that the different ages in Artemia water cultured with Dunaliella salina had a significant effect (p < 0.05) on salt characteristics. The best result was D7 which is salt from Artemia cultured water with Dunaliella salina as a natural feed with water age 7th day. Their respective values are 0.66a + 0.33 water content, 91.55 + 0.32 NaCl, 0.87 water-insoluble part, 0.39% + 0.01 Ca, and 1.25a + 0.05 Mg.

  • Determination of The Best Concentration of Chitosan as a Recirculation
           Filter for Growth and Survival of Tilapia (Oreochromis niloticus)

    • Authors: Miska Sanda Lembang, Widiawati Widiawati
      Pages: 359 - 366
      Abstract: Tilapia (Oreochromis niloticus) is a cultivated commodity that is widely developed because of its economic value and high nutritional content. However, in aquaculture activities, problems such as water pollution reduce water quality. This problem means continuous water changes to maintain water quality. A recirculation system can be a solution by reusing water. The use of filters is an important factor in a recirculation system. One alternative filter is chitosan derived from crab and shrimp shell waste. This study aims to determine the optimal concentration of chitosan as a recirculation filter. The study was conducted experimentally using a completely randomized design with four treatments and three replications. Each treatment is a variation of the concentration of chitosan as a filter. Analysis of measurements carried out was absolute weight growth, specific growth rate, survival, and water quality. Based on the ANOVA results, each treatment had a significant effect on the absolute weight growth of tilapia, P<0.05, with P3 being the most significantly different. At the same time, the specific growth rate and survival of tilapia did not significantly affect P>0.05. The water quality measurements showed that the temperature, pH, ammonia, and DO values ​​were still by the quality standards of tilapia aquaculture, with P3 treatment, which gave better water quality results. Based on the study results, the optimal concentration of chitosan as a filter in supporting tilapia growth was in the P3 treatment, which was 50 mg.

      Pages: 367 - 379
      Abstract: Unsustainable use of fish meal as protein and lipid ingredients in aquafeed has driven the search for alternative. Black soldier fly (BSF) (Hermetia illucens) larvae have been widely studied for the substitution purpose. This study aims at investigating the effect of solid fermentation of pelleted diets containing BSF larvae meal (BSFLM) on the growth performance of catfish Clarias sp. Four feed pellets were formulated: F1 (non-fermented, 60% BSFLM), F2 (fermented, 60% BSFLM), F3 (non-fermented, 50% BSFLM), and F4 (fermented, 50% BSFLM). These formulated diets and commercial feed pellets (positive control) were separately fed to the catfishes in 5 aquaria (10 fishes per aquaria in triplicate). Results showed that the fermentation increased the protein level by 10–11%, but kept the crude lipid concentrations unchanged. Specific growth rate (SGR) and weight gain (WG) profiles for fermented feeds F2 and F4 were higher than the non-fermented feeds F1 and F3, respectively. F4 gave the best feed conversion ratio (FCR) of 1.78, which was 15–25% more efficient than F1, F2, and F3. Compared to the commercial feed, the 4 formulated feeds underperformed by around 50% in all of the growth parameters except survival rates (SR) which were not significantly different (93–100%).

      Pages: 380 - 390
      Abstract: The recent global increase in demand for catfish products has led to intensive catfish farming, favoring Aeromonas infections. Therefore, there is a need to enhance the current management method of Aeromonas infection in catfish. This study evaluated the efficacy of adding vitamin C to Oxytetracycline in the treatment of Aeromonas infection through the development of skin lesions, mortality and serum antioxidant defense system. One hundred and five juvenile catfish were randomly assigned to seven groups (n=15). The first group served as control and was neither infected nor treated, while the other groups were infected with Aeromonas hydrophila. Seventy-two hours after inoculation, catfish in groups 2-7 were treated as follows: no treatment, Oxytetracycline through bath, Oxytetracycline through feed, Oxytetracycline through bath with 500 mg of vitamin C in water, Oxytetracycline through feed with 500 mg of vitamin C in water and 500 mg of vitamin C only in water, respectively. The treatment was done for five consecutive days. Behavioral changes, clinical signs and mortality were observed. Data were presented as Mean±SD and analyzed using descriptive statistics or One-way Analysis of Variance (ANOVA) and Tukey's Test. p <0.5 were regarded as significant. The cumulative percentage mortality in groups (Groups 5 and 6) supplemented with Vitamin C was 26.7 and 33.3 compared to 90% and 46.6% in groups 2 and 4, respectively. The results showed that adding vitamin C to Oxytetracycline reduced the development of skin lesions and mortality. Therefore, Vitamin C is recommended to manage Aeromonas hydrophila infection in catfish.

      Pages: 391 - 401
      Abstract: Fishery products are types of commodity with various levels of development including the addition of food additives. They are very susceptible to patogenic microbial contamination hence they can cause food poisoning and cause disease outbreaks in consumers. In this study, tuna fish spiked with Salmonella spp., Escherichia coli, and Listeria monocytogenes bacteria is examined for the bacteria contamination. The examination of these patogenic bacteria is carried out using multiplex PCR (mPCR), a modern technique developed to detect target DNAs of bacteria simultaneously. The results of the examination are compared to biochemical test for sensitivity and time-efficiency. Based on the results obtained, mPCR method is ±1250-fold more sensitive and ±80-fold more time-efficient than the biochemical tests. Therefore, mPCR method could be recommended to be used as a tool for detection of bacteria in fishery products.

  • Correlation of Density and Water Quality to Cortisol of Cantang Grouper
           Fish (Epinephelus fuscoguttatus X Epinephelus lanceolatus) in Floating Net
           Cages

      Abstract: Cantang grouper is a hybrid resulting from crosses between female tiger grouper (E. fuscoguttatus) and male kertang grouper (E. lanceolatus). Cultivation with floating net cages is one of the attempts made to cultivate cantang grouper fish. Problems that arise are the non-uniformity of the size of the fish when harvesting, this problem can lead to a decrease in selling prices and maintenance that tends to be longer. Metabolic disorders in living beings can be caused due to physiological stress and one of the causes can arise from water quality. Water quality is closely related to feeding and stocking density because the increase in feed and stocking density can affect the accumulation of feces to stress which causes slow growth. This study was conducted to find out the influence of density and water quality factors that play the most important role in the stress of cantang grouper fish based on indicators of cortisol levels. Cortisol testing is performed using the elisa method with Bioassay Technology Laboratory E0014Fi kit type. Data are processed using multiple linear regression test analysis that serves to determine the relationship and influence of the free variable (independent) X on non-free variables (dependent) Y. Regression analysis is used to determine the relationship between factors that are causal relationships. After the regression test, then the Analysis of Variance (ANNOVA) test is conducted, to find out the difference and influence of dependent parameters with significantly independent. There is a strong influence and correlation between water quality factors simultaneously to the cortisol levels of cantang grouper fish in floating nets, as can be seen from the R value of 0.546. The most influential water quality factor was nitrite with an effect of 19.7%. The next most significant water quality factor was ammonia with an effect of 37.1%. The indicated cortisol value can be known that fish are not in a state of stress due to increased NO2 and NH3. Density has no significant effect on cortisol because of its significance value above (p>0.05).
