Abstract

Highlight Research Most businesses, including dried fish processing, are decided and conducted under conditions of uncertainty Each type of fish that is processed has different risks, both in terms of the source, level, and impact of the risk Fish processing SMEs in Bengkulu Province face moderate business risk on all sources of risk, except production risk Three important strategies to prevent high production risk, namely, the formation of joint business groups, the introduction of business risk insurance, and the downstream processing of processed dried fish products   Abstract Every business always faces risks, including micro, small, and medium enterprises processing dried fish. Thus, it is crucial to examine the risk's sources, impacts, and response to risk. This research aimed to analyze the risk management process by identifying the risk sources, analyze the probabilities and risk effects, and design alternative strategies to prevent and control business risk that might be faced by MSMEs dried fish in Bengkulu Province. A total of 273 dried fish processing MSMEs were surveyed and interviewed. The data were analyzed using descriptive statistics and risk management approach. The main risk faced by dried fish producers was the production, included the raw material availability, input prices, and output prices. Each type of dried fish had different probability of risk occurrence where Kerong, Teri, and Gaguk had a high probability of risk occurrence despite their low impact on the scarcity of raw material availability. Moreover, Teri, Kepala Batu, and Bleberan had a high probability and impact risk in the input price. Considering the output price, only Kepala Batu is observed to have the probability and risk impact. Three strategies were designed to prevent and control risk, namely the establishment of joint business groups, introduction of business risk insurance, and downstream processing of dried fish products. SME fish processing does not encounter significant business risks. All risk sources are still regarded as moderate, with the exception of the production risk, which has a high-risk level.

Abstract

Highlight Research Fusarium symbiont Agelas sponge has antibacterial activity against aureus and E. coli Multi Drug Resistant Fusarium can grow on modified media soursop juice (SJ) and ginger juice (GJ) and has different inhibitory abilities against bacteria test Fusarium bioactive compounds were analyzed and purified by HPLC Based on TLC visualization, one of the bioactive compounds contained in Fusarium is a steroid group   Abstract Marine symbiont fungi, specifically, are likely to have antibacterial properties. The production of secondary metabolites in cultures is strongly influenced by nutrient availability. This study aimed to study the modified media for the cultivation of Fusarium sp. and its antibacterial bioactivity. Fusarium sp. was isolated from Agelas sp. sponge collected from Riung Sea, East South Nusa, Indonesia. In this study, the modified media was soursop juice (SJ), ginger juice (GJ), and sago (S). The fungal mycelium was cultured and scaled up for 7–14 days until the mycelium achieved maximum growth. A filtration funnel and HPLC were used to purify the bioactive compounds. The diffusion agar method was used to test antibacterial activity against the multi-drug resistant (MDR) Staphylococcus aureus and Escherichia coli. The results indicated that Fusarium sp. could grow on soursop juice and ginger juice but could not grow on sago media. The inhibition zone produced by the filtration fraction of Fusarium sp. from each media differed. The soursop juice media produced the largest inhibition zone against both S. aureus (11.56 mm ± 0.140) and E. coli (12.16 mm ± 0.094) at 100 Î¼g/disc. The ginger juice (GJ) and soursop juice (SJ) media are promising as alternative culture media for Fusarium sp. The structure of the bioactive compound Fusarium sp. from GJ and MJ media culture can be further investigated using NMR.

Abstract

Highlight Research The growth rate was higher when Chlorella was induced by Azospirillum brasilense. The carbohydrate content increased when combined with Azospirillum brasilense. Determination of astaxanthin accumulation in Haematococcus pluvialis. Define condition favoring astaxanthin accumulation in Haematococcus pluvialis. Abstract Dunaliella sp. is a potential natural source of carotenoid pigments such as astaxanthin, β-carotene, and lutein. Dunaliella sp. can also accumulate other valuable products such as glycerol and protein. Another species is Azospirillum sp., which is known as microalgal growth-promoting bacteria. These bacteria are often cultured with microalgae because they contain indole-3-acetic acid, which can significantly increase the growth of microalgae. This study aimed to examine the pigment content in mixed culture of Dunaliella sp. and Azospirillum sp. after being treated with different light intensity treatment. In this study, Dunaliella sp. were cultivated by mixing with Azospirillum sp. under light stress. Two treatments were performed at light stress intensity of 3000 and 6000 lx. Light intensity is widely used as an important parameter in cultivation, which can affect the growth and production of microalgal biomass. In addition, spectrophotometric UV-Vis based measurement was conducted to investigate every single pigment content in all treatments under light stress for eight days. The number of cells, carotenoid pigments, and astaxanthin had increased significantly. Pigments of chlorophyll a and chlorophyll b also significantly increased at lower light treatments. Based on the results, the bacterium Azospirillum sp. and high light intensity significantly increased the growth and cell division of microalgae. Therefore, the combination of Azospirillum sp. and light stress intensity in microalgae cultivation could increase the growth and pigment of Dunaliella sp.

Abstract

Highlight Research The COVID-19 pandemic has caused an increase in the price of marine resources and the income of coastal communities has been affected. The government and the authorities need to come out with several incentives to control this condition and the request for fish markets can be met customarily without rising prices and declining marine resources. Malaysian Fisheries Development Authority (LKIM) a body that has a direct link to the fishing industry needs to ensure that all fishermen's associations participate in the purchase and marketing of fishermen's catch. Adaptation of fish producers will pave the way for all coastal communities to develop more organized fishing systems and sufficient food sources   Abstract COVID-19 has a significant impact on the fishery industry, economy, and food supply. The government of Malaysia imposes a Movement Control Order (MCO) to curb the spread of COVID-19 infection. Although the MCO implementation has benefits in terms of public health, it has affected the fishery industry and the livelihood of coastal communities in Malaysia. This study aimed to identify the impact of the COVID-19 pandemic on the fishery industry and their livelihoods during that period of calamity. Qualitative research and thematic analysis were employed to seek deeper information on the real situation that retards the fishing activities to the opt stage. COVID-19 has already revealed gaps in health care, the economy, and food systems. The findings obtained can provide recommendations to the government to provide initiatives to fishermen to help them maintain and improve their livelihood. However, this study has limitations as the number of respondents is relatively small due to the restrictions of movement allowed by the government. Future studies could be further enhanced in terms of the impact of COVID-19 after movement restrictions have been loosened and could use a quantitative approach to obtain significant data.

Abstract

Highlight Research A molecular marker for shrimp selection in disease resistance. Single nucleotide polymorphisms (SNP) in the ALF gene strongly correlate with shrimp resistance to WSSV infection. Higher ALF gene expression in survivor shrimp. SNP as molecular marker inherited in the first generation (G1) shrimp. ARMS-PCR method successfully detect SNP in the shrimp ALF gene. Abstract The Pacific white shrimp (Litopenaeus vannamei) is Indonesia's main export commodity, but its production is constrained by the white spot syndrome virus (WSSV). Selective breeding of disease-resistant broodstock based on single nucleotide polymorphism (SNP) in the anti-lipopolysaccharide factor (ALF) gene is an alternative strategy for solving the disease problem. This study aimed to detect the SNP g.455 A>G in the anti-lipopolysaccharide factor (ALF) shrimp gene, evaluate the correlation of SNP with WSSV-resistance trait, analyze the expression level of immunity genes and genotype frequencies of the WSSV-resistance population shrimp and analyze the SNP inheritance in the first generation of selected shrimp. A total of 120 individuals from 4 families were used to detect the SNP marker using tetra-primer amplification refractory mutation system-polymerase chain reaction (ARMS-PCR). The correlation of the SNP marker with survival rate (SR) was analyzed using a general linear model (GLM) between genotype frequencies and SR. Genotypic similarities between broodstock and pedigree were analyzed using Chi-square. SNP g.455 A>G was successfully detected using the ARMS-PCR method and had a strong correlation between the marker and SR (p-value of AA = 0.012; AG = 0.359, and GG = 0.001). The resistant population has significantly higher ALF and SOD gene expression levels and AA genotype frequency. The SNP marker was inherited, so the broodstock and pedigree have the same genotype frequencies according to chi-square analysis (χ2 = 0.46 and p-value = 0.497). These results suggested that the g.455 genotype AA could be selected to produce WSSV-resistant Pacific white shrimp.

Abstract

Highlight Research Use of maggot oil as an addition to feed can increase the level of feed consumption of carp. The addition of maggot oil ( illucens) had a significant effect (P<0.05) on TFC, FCR, FUE, SGR, and survival of common carp. The use of maggot oil can be an alternative to using feed that is more effective and economical.   Abstract The demand for common carp (Cyprinus carpio) either its seed or consumption measures has increased every year. Fish growth can be increased by adding nutrients in the form of animal oil sources. An alternative ingredient that can be used to support fish growth with good nutritional content and relatively inexpensive is maggot oil or black soldier fly (H. illucens) oil. The purpose of this study was to determine the effect of maggot oil (H. illucens) in artificial feed on the growth performance of common carp and to determine the best dose of maggot oil. This study used a complete randomized design (CRD) with four treatments and three replicates: A, B, C, and D with the addition of maggot oil doses of 0%, 10%, 15%, and 20%, respectively. The test fish used was a common carp fry measuring 3.59±0.06 cm, 0.79±0.05 g. Observation time was 30 days with a stocking density of 15 fish/aquarium. The results showed that the addition of maggot oil (H. illucens) had a significant effect (P<0.05) on TFC, FCR, FUE, SGR, and survival. Based on the results of the study, the best dose was obtained in the addition of 15% maggot oil with value of TFC 10.57±0.26 g, FCR 1.52±0.03, FUE 65.43±1.54%, SGR 1.57±0.04%/day, and SR 95.56±3.85%. For further research, it is possible to use magot oil to increase carp production.

Abstract

Highlight Research Mariculture is one of the activities that can pressure the aquatic environment. Mariculture activities are carried out by considering the sustainability aspects of environmentally friendly implementation. The suitability of the location for mariculture activities refers to the geographical and hydro–oceanographic conditions seen from the waters' physical, chemical, and biological parameters. The suitability index produced using multiple approaches (GIS-based AHP) can be used to determine the potential locations for mariculture development.   Abstract Potential mariculture activities in the Dampier Strait Conservation Area, which are indicated by the availability of water space and local commodities, can have a multiplier effect on socio-ecological aspects. Therefore, reasonable development steps are needed to carry out environmentally friendly aquaculture. This study aims to determine the potential use of water space for the development of mariculture activities based on the level of suitability using multiple approaches. Suitability analysis was carried out with Geographic Information System (GIS) based on the Analytical Hierarchy Process (AHP) by considering the area's characteristics using several aspects seen from the geographical conditions and water quality (physical, chemical, and biological). Based on the suitability analysis results, the potential water space that can be used for mariculture development activities, namely seaweed and pearl oyster cultivation was 1,130.45 ha (0.49% of the overall space allocation 232,588.59 ha). A justification was then carried out to determine a suitable location in terms of its accessibility and environmental friendliness. The analysis has shown promising results in determining potential locations for developing mariculture activities for seaweed and pearl oyster commodities based on sustainable and environmentally friendly cultivation.

Abstract

Highlight Research Sex reversal for orange-spotted grouper Epinephelus coioides The application of 17α-methyltestosterone induce sex change The stability of sex change need more investigation Abstract The occurance of hermaphrodites in grouper fish causes a scarcity of male parents, so an alternative is needed to accelerate sexchange to male at a young age. The present study was expected to scrutinize the mechanisms of sex-change in fish in the early change process, and whether the testis converted from immature ovary using 17α-methyltestosterone (MT) would recover after the termination of MT treatment. MT-induced sex-change and 5-aza-2'-deoxycytidine (5-Aza) were connected as DNA methylation inhibitors to comprehend the alternation of gonadal soma cells. The orange-spotted groupers were used  at the developmental ages and fed a diet containing MT at 50 mg/kg for three months and then a normal diet for a month. In the first week and second week fish injected with 5-Aza intraperitoneally during the MT-oral administration. Most of the fishes in the control group had immature ovaries, but all the females fed with MT, had immature spermatogenesis. However, one month after the withdrawal of MT treatment, the sex of the fish returned to female-like even though the fish have undergone MT-induced masculinization. This outcome demonstrates precocious sex-change from under yearling, orange-spotted grouper utilizing oral MT treatment is impermanent. All the females of 5-aza treatments showed no spermatogenic cells.  In this study, lower growth rates were demonstrated by the MT-treated groups. The impact of this metabolic change was clear after the end of the hormone oral administration since the decreased growth of the groups treated for three months.

Abstract

Highlight Research S. platensis has been analyzed for its productivity. Analysis of the productivity of S. platensis on the use of fish culture wastewater media. S. platensis production can be increased by aquaculture wastewater. Aquaculture wastewater enhances the production of cell density, SGR, biomass, protein, and carotenoid of S. platensis. Abstract Increased productivity of Spirulina sp. in the form of high protein, carotenoids, and biomass content can be achieved by improving its nutrient supply. Inorganic fertilizers are nutrient sources, which are generally used in the culture of this organism on laboratory and industrial scale, but there are several drawbacks, including their high costs and limited availability. Several studies have also reported the use of zarrouk fertilizer as a standard culture medium for Spirulina platensis. Therefore, this study aims to determine the effect and the best concentration of fish culture wastewater treatment in Spirulina platensis culture using biomass, protein content, and carotenoid pigments as indicators. A two-factorial completely randomized designs (CRD) was used in this study, where the factors include the dose of organic waste and Zarrouk fertilizer. The microalgae samples, namely S. platensis were cultured using fresh water. This research consists of two factors. The first factor is the dose of organic waste, and the second factor is the dose of Zarrouk fertilizer. The wastewater treatment consisted of 0, 2, 4, and 6 ml/L, while Zarrouk dosages include 0, 0.5, and 1 ml/L. The best results were obtained from the sample treated with 6 ml/L aquaculture wastewater without the addition of Zarrouk. Furthermore, this treatment gave biomass production of 0.781 g/L, 50.441% protein, and 1.246 mg/L carotenoids. Based on the results, S. platensis culture can be carried out using fish culture wastewater without the addition of Zarrouk fertilizer.

Abstract

Highlight Research Development of immunostimulant from natural sources is a promising approach to improve the immune status of fish Dietary administration of sodium alginate from Padina australis at 2.0 g/kg was an effective immunostimulant for red tilapia Red tilapia fed diet with sodium alginate significantly increased innate immune responses of TLC, PA, respiratory burst, SOD, TPP, lysozyme, and ACH50 activity Red tilapia fed diet with sodium alginate significantly modulated immune genes expression of GPx, TNF-α, IFN-γ, IL-10, TGF-β1, and Hepcidin Abstract The study of immunostimulant derived from natural sources has received considerable attention in recent years. Indonesian coasts have various sources of immunostimulant, especially brown algae, which are rich in alginate. This research investigated innate immune response and immune genes in red tilapia (Oreochromis sp.) after being fed diets supplemented with sodium alginates (SA) from a brown alga, Padina australis, originating from Awur Bay, Jepara, Indonesia. This work provided comprehensive information regarding the interaction of cellular-humoral immunity and immune gene expression. Red tilapia was fed with SA-containing diet at doses of 0, 2, 3 and 4 g/kg for 12 days, then blood samples were collected on days 0, 3, 6, 9, and 12 to evaluate the total leucocyte count (TLC), phagocytic activity/index (PA/PI), respiratory burst, superoxide dismutase (SOD), lysozyme, alternative complement (ACH50) activity, total plasma protein (TPP), and immune genes expression (blood sample on day 6). The immunological parameters improved in response to the administered doses and period. Dietary SA enhanced total leucocyte count, phagocytic activity, respiratory burst, superoxide dismutase, lysozyme, and ACH50 activity, whereas the phagocytic index and total plasma protein were not significantly different. Furthermore, the mRNA levels of antioxidant-related gene (GPx), pro-inflammatory cytokines (TNF-α and IFN-γ, except for IL-1β), and antimicrobial peptides (Hepcidin) were upregulated. Meanwhile, anti-inflammatory cytokines (IL-10 and TGF-β1) were downregulated. Supplementation SA diet at 2.0 g/kg as the lowest dose revealed the most effective effects on innate immune and immune genes expression. Dietary SA was a potential immunostimulant in red tilapia aquaculture.
