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.

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.

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%).

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.

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.

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).

Abstract

This study aims to determine the effect of fermentation duration on the nutrient composition of seaweed liquid organic fertilizer (Sargassum sp). This research was conducted from May to June 2017 at  The University of Muhammadiyah Parepare. Test materials used in the form of seaweed and lactobacillus. The container used in the implementation of this research is 6 bottles of 1000 ml size, before the bottles are used first the bottles are washed clean. Then each bottle is filled with extracts of Sargassum sp. as much as 800 ml and 40 ml of probiotics. Two bottles of treatment A (without fermentation), 2 bottles for treatment B (7 days fermentation), 2 bottles for treatment C (14 days fermentation). The design was a completely randomized design (CRD) with 3 types of each treatment. The results showed that micro nutrients that the iron (Fe) were obtained highest in treatment C (concentration 162 ppm), Silica (Si) in treatment A (100 ppm), manganese (Mn) in treatment B (29 ppm). For the highest macro nutrients potassium (K) obtained in treatment C (concentration 0.52%), Calcium (Ca) in treatment B (0.33%), Sulfur (S) in treatment C (0.31%) , Chlorine (Cl) in treatment C (concentration 0.27%). The research concludes that the length of time of fermentation affects the nutrient content of liquid organic fertilizer seaweed.

Abstract

The problem arises in vanamei shrimp cultivation is the emergence of diseases, such as vibriosis caused by Vibrio parahaemolyticus. Jatropha leaf extract can be used as an immunostimulant because it contains bioactive compounds namely flavonoid, tannins, saponins, and alkaloids. This research used a completely randomized design (CRD) with 5 treatments with 3 replications. The treatments used were; P1 (feed without extract and bacterial infection); P2 (feed without extract and NaCl injection); P3 : Feed + 1% + bacterial infection; P4 : Feed + 2% extract from feed and bacterial infection, P5 : Feed + 3% extract of feed and bacterial infection. Based on the results of the study, the administration of Jatropha leaf extract was able to increase the highest SR value of P2 by 88.3%, the highest THC value of P5 at 24.46 x 106 cells/ml, DHC values ​​such as hyaline cells ranged from 36.67-71%, granular cells ranged from 17-38.57%, and semigranular cells ranged from 12-24.67%, the highest AF value in P5 was 77.25%, and the lowest TBC value was at P2 of 6 x 108 CFU/ml, the lowest TVC value was at P2 of 0.56 x 106 CFU/ml. The higher the dose of extract given, the higher the THC and AF, besides that, Jatropha leaves were also able to increase the SR value and suppress the growth of total bacteria and total Vibrio in shrimp intestines.

Abstract

The purpose of this study was to determine the survival rate (SR), the Average Daily Growth (ADG), and the Feed Conversion Ratio (FCR) of Nile tilapia (Oreochromis niloticus) with a dynamic system model. The dynamic system model is used to determine the optimal value of the three variables. The results showed that the survival rate, average daily growth, and feed conversion ratio of tilapia cultivation were 93% (SR), 3.2gr/day (ADG), 0.73 (FCR). In this research, tilapia  production were 14,199gr, the amount of feed were 10.344gr and the length of cultivation were 65 days. It was hoped that the dynamic system model design could have tilapia farmers to develop aquaculture businesses that was more environmentally friendly, effective and efficient.

Abstract

This paper presents an experiment in which two different fish culture system types were evaluated for the short-term commercial culture of fingerlings of Clarias gariepinus maintained at half the recommended stocking rate; 82.5/m3 in 2 m3 water volume in indoor blue fiber-glass tanks (IFT) and outdoor black plastic tanks (OPT). The research objectives were to assess the suitability and commercial viability of the tanks. Initial mean body weight of graded fingerlings of C. gariepinus for IFT and OPT were 11.32±2.25 g and 10.92±2.44 g (mean±standard deviation) respectively. The study lasted for eight weeks with the fish attaining post-juvenile sizes of 174.95±74.30 g and 178.84±52.04 g (mean±standard deviation) in the IFT and OPT respectively which were not significantly different at p > 0.05. Survival at termination was 81.21±0.0% and 81.21±2.5% for IFT and OPT respectively. As fish attained larger sizes of 100 g and above between weeks 6 and 8, skin lesions and frayed fins were observed in comparatively more of the indoor reared fish than the outdoor reared fish. It may be concluded that the systems are not vastly different in terms of resultant survival and growth performance of the African catfish, however, the culture duration may be halved when maintaining the reported stocking rate in order to prevent distress as a fallout of aggression as they increase in size.
