Abstract

The biofloc system is a solution for intensive cultivation activities. This is because in biofloc system the are heterotrophic bacteria that can reuse waste from cultured organisms so as to improve water quality. However, the biofloc system can cause high nitrite production if the dissolved oxygen concentration in the water is below the optimum value. High nitrite concentrations can cause brown nitrite, causing fish to suffocate even though the oxygen concentration in the water is sufficient. Polyculture can be a solution to reduce the concentration of biofloc so that brown nitrite can be prevented. Therefore, a research was conducted with the aim of knowing the effect of the composition of the best polyculture biota in order to produce high cultivation performance. The ratio of tilapia and catfish used included 80% catfish and 20% tilapia fish (treatment A), 70% catfish and 30% tilapia fish (treatment B), 60% catfish and 40% tilapia ( treatment C), and 100% catfish (treatment D). Maintenance is carried out for 60 days where feeding is done on a restricted basis. The results of the research carried out showed that the best FCR, ADG and SR were in treatment C with consecutive values of 1.27 ± 0.02 (FCR), 1.4 g/day (ADG) on the last maintenance day, 95.11 ± 1.02% (SR). This study shows that the performance of cultivation in biofloc systems in polyculture is better than monoculture.

Abstract

The stress level of vannamei shrimp (Litopenaeus vannamei) is affected by increased density and several genes are expressed under the condition. This study aimed to determine the expression of genes encoding white shrimp stress after density treatment and the infectious myonecrosis virus (IMNV) challenge test. A completely randomized design (CRD) was carried out with 6 treatment groups, i.e. 3 different stocking density groups without IMNV infection (100, 200, and 400 shrimp/m2) and 3 different stocking density groups + IMNV infection (100, 200, and 400 shrimp/m2). In addition, a shrimp density of 400 shrimp/m2 reported the fastest rate of developing the IMNV virus as seen from the clinical symptoms. The lowest cumulative number of shrimp deaths was at a density of 100 shrimp/m2 and was caused by the IMNV virus confirmed through RT-PCR. Expression of stress-coding genes was divided into upregulated and downregulated characteristics. The upregulated genes were lectin and translationally controlled tumor protein (TCTP), while the downregulated gene was Toll Receptor. The results showed that the expression of genes related to immunity in L. vannamei was upregulated after pathogen challenges such as lectin and TCTP, meanwhile, the Toll receptor gene was downregulated. Further study should also be performed to measure the expression of the three genes in revealing the immune pathways.

Abstract

The demand for Siamese catfish seeds continues to increase every year. Therefore, it is essential to maintain high-quality seeds in adequate quantities, supported by the availability of natural feed such as bloodworms (Tubifex sp.). One of the efforts to improve hygiene and reduce pathogenic bacteria is through the sanitation treatment of feed using fermented tofu waste and mustard greens waste. The fermentation of tofu waste and mustard greens has a high protein content, which can enhance the nutritional value essential for the growth of fish seeds. The objective of this research is to analyze the effectiveness of using hygienic bloodworms treated with fermented tofu waste and mustard greens waste on the performance of Siamese catfish seed breeding. The method employed is a Completely Randomized Design (CRD) with four treatments and three replications. The research data were analyzed using ANOVA statistical tests and Tukey's post-hoc test at a 5% significance level. The sanitation treatment of feed with the addition of fermented tofu waste and mustard greens resulted in the highest nutritional content and the highest abundance of beneficial bacteria on the fifth day of maintenance. The results showed a significant effect () on the absolute growth and specific growth rate of Siamese catfish seeds. The absolute length growth of the Siamese catfish seeds was 9.37±0.044 mm, while the absolute weight growth was 0.08±0.0169 grams. The specific length growth rate of the Siamese catfish seeds was 7.10±0.017%, and the specific weight growth rate was 18.35±0.025%. The survival rate of Siamese catfish seeds across all treatments reached 98%. The sanitation treatment of natural bloodworms with fermented tofu waste and mustard greens is recommended to enhance the nutritional content of bloodworms and accelerate the growth of Siamese catfish seeds.

Abstract

Silk worms (Tubifex sp.) are a type of natural food that is widely used for the needs of fish farming activities, especially in the freshwater fish hatchery phase. This study aimed to determine the effect of providing dried feed/media with varying doses on the productivity of silk worms. The study was conducted using a Completely Randomized Design (CRD) with 3 treatment groups and 4 replications which included administration of dry media at a dose of (P1) 150 grams/m2 (P2) 250 grams/m2 (P3) 350 grams/m2. The initial silk worm seeds were obtained from silk worm collectors or sellers in Cipayung-East Jakarta. Maintenance of silk worms was carried out for 55 days. The results of the diversity analysis showed that there was a significant difference in the dose of dry media in cultivating silk worms (P≤0.05). The best absolute weight growth, population growth, and productivity were shown in the media treatment with a dose of 250 grams/m2 (P2) with absolute biomass growth of 408.7 grams, population growth of 209,381 individuals, and productivity of 1.3/m2/cycle. Most of the water quality observation results are in a relatively optimal range. Silk worms have the potential to be developed as a safe, environmentally beneficial, and inexpensive natural food for cultivated animals.

Abstract

The need for high-quality natural feed for fish farming and aquaculture industry is increasing along with the rapid growth of the fisheries sector worldwide. However, the problem faced is the great dependence on the availability of worms from nature so that silk worm cultivation is very important to ensure the availability of quality natural feed for fish farming. This study aims to determine the effect of the use of synthetic substrates made from different materials on the productivity and absolute weight growth of silk worms, as well as to determine the effectiveness of harvesting in each treatment and business analysis. This experiment was designed in a completely randomized design (CRD) with 3 treatments which are: P1 (Cotton substrate),  P2 (Net substrate), and K (as control).  Each treatment was quadriplicated and the data analysis was run in One-way ANOVA for CRD. Worms were kept for 30 days with the results of silk worm productivity. The highest productivity figures were in P2 with a value of 689.48 ± 52.80 g / m2 / cycle and K 622.52 ± 121.60 g / m2 / cycle. Statistical tests showed that there was no significant effect (sig.>0.05) of substrate use on silkworm productivity. Absolute weight growth K 12.75±12.25 g/m2/cycle, P1 13.5±7.59 g/m2/cycle, P2 19.5±5.32 g/m2/cycle. Water quality parameters during the study period ranged from optimal values. Business analysis was assumed and the results of the business analysis obtained were loss and not feasible. It can be concluded that the synthetic substrate used did not provide significant benefits in silkworm cultivation. Keywords: Silkworms, Substrate Synthesis, Productivity
