Abstract

Curcuma spp. is a phytobiotic with potential application in fish farming. This study aimed to evaluate the potential of Curcuma zedoaria, Curcuma aeruginosa and Curcuma mangga extracts in striped catfish infected with Aeromonas hydrophila. The study used a complete randomized design (CRD) consisting of six treatments: KN (negative control), KP (positive control, fish infected without treatment), PE (C. zedoaria extract 6.25 g kg-1), HE (C. aeruginosa extract 6.25 g kg-1), ME (C. mangga extract 6.25 g kg-1) and KE (combination of C. zedoaria extract 2.1 g kg-1 + C. aeruginosa extract 2.1 g kg-1 + C. mangga extract 2.1 g kg-1). A total of 360 striped catfish, 10 ± 0.5 cm were kept in 18 aquariums measuring 50 × 40 × 35 cm3 and fed the treatment for 30 days. The challenge test was conducted on day 31 by injecting A. hydrophila suspension (106 colony-forming units (CFU) mL-1) intramuscularly into fish. The results showed that the treatment administered were able to stimulate the expression of interleukin-1â, interferon-ã 2a, 2b genes, increase the number of red and white blood cells, hematocrit, hemoglobin, phagocytosis activity, respiratory burst, reduce the population of A. hydrophila in the intestine, and reduce tissue damage in striped catfish. Striped catfish treated with the extracts showed significantly higher survival rates (p<0.05) compared to the positive control group. The survival rates were: KN (100.00 %), KP (53.33%), PE (93.33 %), HE (91.67 %), ME (93.33 %), and KE (88.33 %). In conclusion, the treatment administered were able to enhance the immune response and resistance of striped catfish infected with A. hydrophila.

Abstract

Pacific white shrimp (Litopenaeus vannamei) cultivation in Indonesia has been carried out since the early 2000s with satisfactory results. This shrimp is able to replace the previously cultivated black tiger (Penaeus monodon), which experienced cultivation failure due to disease attacks. The pond construction used includes an earthen pond, a lining pond, and a concrete pond, which are equipped with paddlewheels as a source of dissolved oxygen. Pacific white shrimp are mostly cultivated using semi-intensive, intensive, and super-intensive systems, depending on technological input and stocking density. Semi-intensive stocking density is around 50 PL/m2, intensive 100 PL/m2, and super-intensive 500 PL/m2, with productivity of 10 tons/ha, 15 tons/ha, and 42 tons/ha, respectively. There are two types of harvests carried out by farmers in Indonesia, namely partial harvests and total harvests. The main aim of partial harvest is to reduce excessive shrimp biomass, as indicated by a decrease in dissolved oxygen content. Problems that often arise during the cultivation process are disease attacks such as white spots and infectious myonecrosis (IMN) caused by viruses, White Feces Syndrome (WFS)  and Acute Hepatopancreatic Necrosis Disease (AHPND) caused by Vibrio parahaemolitycus and Enterocytozoon hepatopenaei (EHP). To increase the productivity of whiteleg shrimp cultivation, the advice given is to minimize disease attacks, namely by installing several biosecurity devices, such as bird scaring devices (BSD), crab protection devices (CPD), and water filtration. In addition, the application of a recirculation aquaculture system, biofloc technology, aquamimicry and whiteleg shrimp cultivation at low salinity (inland) can be an alternative cultivation in the future.

Abstract

Tawes fish (Barbonymus gonionotus), also known as lampan, is an indigenous freshwater species with significant economic value and cultivation potential. However, suboptimal growth remains a common challenge in aquaculture. Hormonal treatments such as thyroxine and rGH are known to enhance metabolic processes, potentially improving egg yolk absorption and larval growth. This study aimed to evaluate the effects of thyroxine and rGH hormone immersion on the rate of egg yolk absorption and development of newly hatched tawes fish larvae. The experimental design employed a CRD with four treatments and three replications: A (thyroxine 0 mg/L + rGH 2.5 mg/L), B (thyroxine 0.1 mg/L + rGH 0 mg/L), C (thyroxine 0 mg/L + rGH 2.5 mg/L), and D (thyroxine 0.1 mg/L + rGH 2.5 mg/L), with hormone immersion conducted for 60 minutes. The results demonstrated that the combined immersion of thyroxine and rGH significantly (P <0.05) improved the absolute weight gain, absolute length increment, and survival rate of tawes fish larvae. The highest values for absolute weight (0.043±0.002 g) and length (12.77±0.15 mm) were observed in treatment D (thyroxine 0.1 mg/L + rGH 2.5 mg/L), while the best survival rate (70.00±2.00%) was recorded in treatment A (thyroxine 0 mg/L + rGH 2.5 mg/L). These findings suggest that the combined use of thyroxine and rGH can effectively enhance the early growth and development of tawes fish larvae.

Abstract

Mahseer (Tor spp.) is a freshwater fish commodity with a high market value. However, its slow growth to reach consumable size has resulted in inadequate production. The aim of this study is to analyze the hybrid vigor - that are heterosis, heterobeltiosis, and growth performance - of a crossbred population of Mahseer (Tor spp) resulting from interspecies breeding. Broodstock of Mahseer from three different species were prepared for reciprocal breeding, producing nine offspring populations consisting of six hybrid offspring and three purebred offspring populations. The breeding process was carried out using artificial breeding methods, employing intramuscularly injected breeding stimulant hormones. Results show that the hybrid population of Tor soro and Tor tambroides exhibits better heterosis and heterobeltiosis in final weight, specific growth rate, and survival rate. The crossbreeding of Tor soro and Tor tambroides also exhibited better growth performance compared to other crossbred population in terms of final weight growth, specific growth rate, and survival rates, which were 64.20 g, 1.42%/day,  and 100% respectively.

Abstract

Diatoms are valuable as natural feed in aquaculture due to their lipid content and the presence of essential polyunsaturated fatty acids (PUFAs), including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). While traditional suspended cultivation has limitations, attached cultivation offers advantages such as lower water use and improved lipid productivity. This study evaluated the growth, biomass, and lipid content of Thalassiosira sp. grown on polycarbonate (PC) and polyvinyl chloride (PVC) as attachment substrates. The control group was cultured in standard suspended cultivation method.  Test attachments substrates were submerged in sterile seawater enriched with F-medium, and growth was monitored for four days.  At day 4 of the culture, cell density was significantly higher on PC (13.08 × 105 cells mL-1) and PVC (13.01 × 105 cells mL-1) compared to the control (7.93 × 105 cells mL-1). The specific growth rate was also significantly higher on both substrates, exhibiting a doubling time of 0.20 days. Biomass accumulation was highest on PC (27.47 mg 100 mL-1), followed by PVC (26.87 mg 100 mL-1), representing increases of 38.39% and 35.37% over the control (19.85 mg 100 mL-1), respectively. Lipid content was higher in the attached culture system, reaching 8.50% on PC and 7.45% on PVC, corresponding to increases of 167.30% and 134.28% over the control (3.18%). These findings highlight the potential of PC and PVC as effective substrates for biofilm-based cultivation of Thalassiosira sp., demonstrating superior growth, biomass yield, and lipid accumulation compared to the suspended culture method.

Abstract

The sustainability of Nile tilapia production faces challenges from motile Aeromonas septicemia (MAS), caused by Aeromonas hydrophila. The use of antibiotics to control MAS has negative impacts on aquatic environments and consumer health. As alternatives, plant-based treatments and vaccination have been increasingly applied to replace antibiotics. This study aimed to evaluate the effects of banana pseudo-stem (BS), a commercial vaccine (CV), and their combination (BS+CV) on the growth, health status, and immune performance of Nile tilapia against A. hydrophila. A completely randomized design was used with five treatments: a negative control (C−), a positive control (C+), BS, CV, and BS+CV—each coated onto feed. Each treatment had three replications. Fish were reared in 36-L aquaria for 42 days to evaluate growth performance, followed by a challenge test with A. hydrophila on day 43. Survival was monitored for 14 days post-challenge. The highest growth performance was observed in the BS treatment compared to the other treatments. Meanwhile, survival rate (SR) and feed conversion ratio (FCR) did not show significant differences (P>0.05) among treatments. After the challenge, survival rates in the BS (96.67%), CV (73.33%), and BS+CV (76.67%) groups were significantly higher (P<0.05) than in the positive control group (50.00%). The BS group did not differ significantly (P>0.05) from the negative control group (100.00%). These findings indicate that BS, CV, and BS+CV enhance the immune response of Nile tilapia against A. hydrophila, with BS being the most effective in improving both growth and disease resistance.

Abstract

Vibrio parahaemolyticus strain that produces PirA and PirB toxins is the main causative agent of Acute Hepatopancreatic Necrosis Disease (AHPND) in vannamei shrimp. This study aimed to evaluate the effect of biofloc application, probiotic Pseudoalteromonas piscicida 1Ub, and their combination on growth, immune response and resistance of vannamei shrimp infected with V. parahaemolyticus strain. This study used a completely randomized design consisting of biofloc-based system treatment with or without probiotic 1Ub and normal seawater as control. All treatment groups were challenged with V. parahaemolyticus AHPND strain at a cell density of 105 CFU mL”1 through immersion, while the negative control was reared without being pathogenic challenged. The shrimp used were in averaged body weight of 1.3 ± 0.002 g, reared for 21 days and fed five times a day at 06:00, 10:00, 14:00, 18:00, and 22:00 WIB. The results showed that the B+Pro combination challenge test treatment resulted the best growth performance (specific growth rate, absolute length gain and feed conversion ratio) (P<0.05) compared to other challenge test treatments. hrimp treated with B+Pro also showed a lower intestinal cell population of V. parahaemolyticus RfR, and significantly higher immune response values (P<0.05) than those of other challenge test treatments and K+. Furthermore, those parameters supported positive impact on final shrimp survival rates in the experiment. This study shows that the application of combination of biofloc and 1Ub probiotic bacteria can significantly protect and increase the resistance of vannamei shrimp to V. parahaemolyticus AHPND infection.

Abstract

The commercially important red seaweed Kappaphycus alvarezii is extensively cultivated for carrageenan production. Despite its economic value, large-scale reproduction and genetic enhancement remain limited due to its low regeneration potential. This study aimed to optimize plant growth regulator (PGR) concentrations for efficient callus induction in K. alvarezii. A completely randomized design was employed, comprising five treatments with varying concentrations of indole-3-acetic acid (IAA) and 6-benzylaminopurine (BAP), along with a control lacking PGRs. A total of 180 explants from meristematic tissues of acclimatized thalli were cultured (30 explants per treatment). The highest callus induction rate (88%) was achieved with 1.50 mg/L IAA and 5 mg/L BAP (Treatment F), with visible callus formation beginning around day 38. A progressive color change from brown to white was observed, indicating active cellular proliferation. Other treatments exhibited lower induction rates, ranging from 0% (control) to 61% (Treatment D). These findings underscore the critical influence of auxin–cytokinin interactions on callogenesis and offer an optimized hormonal regime for improving in vitro culture efficiency. The established protocol provides a valuable platform for future large-scale propagation and genetic improvement strategies in K. alvarezii, contributing to the advancement of seaweed biotechnology.

Abstract

Cupped oyster has emerged as the predominant mollusk farmed domestically in Vietnam because of its exceptional adaptability to the local subtropical and tropical climates. However, considerable confusion remains regarding the identity of the cultivated species due to the taxonomic ambiguity between Portuguese cupped oyster (Crassostrea angulata) and Pacific cupped oyster (Crassostrea gigas). This study aims to clarify the species identity of the most commonly farmed cupped oysters in Vietnam and to evaluate genetic diversity and the suitability of oyster strains for a breeding program including three Vietnamese strains (Quang Ninh, Khanh Hoa, and Vung Tau) and one wild population from Taiwan. Based on mitochondrial DNA cytochrome c oxidase subunit I (COI) sequences, our results confirmed that all samples in Vietnam and Taiwan are C. angulata. Furthermore, this study performed genetic analyses using mtCOI sequences and five microsatellites. Populations in Vietnam and Taiwan maintain high levels of genetic diversity, with the average number of alleles per population varied between 7.80 to 16.0, and there was no statistical difference between observed and expected heterozygosity (P > 0.05), except in the hatchery population Vung Tau. The samples collected from this population suffered a great loss of heterozygosity and occupied the highest Fis value (Fis = 0.3), which is likely due to the small size of founding stock and long-term artificial breeding by local hatchery farmers, resulting in a strong genetic bottleneck and inbreeding depression. Pairwise FST calculated by microsatellites with a range of 0.043 to 0.093 revealed significant (P < 0.05) levels of genetic differentiation among oyster lines. Collectively,  our findings clarify the taxonomic status of farmed oysters in Vietnam and highlight the importance of crossing among different strains in future breeding programs to maximize the genetic gain and avoid inbreeding, especially when using the oyster strain from Vung Tau.
