Abstract:

The most common problem in barramundi Lates calcarifer seedling production is the high mortality (> 90%) caused by nervous necrosis virus (NNV) infection. This research aims to evaluate the resistance and gene expression of barramundi challenged by NNV. Two populations were used in this study, i.e., Australian, and Situbondo-originated barramundi populations. The immune-related gene expression levels in the liver, head of kidney, and spleen were observed at 48 and 96 hours after post-infection (hpi). Barramundi’s survival and blood parameters were evaluated post-NNV infection. The results showed that the highest survival was revealed in Situbondo’s barramundi (42.0±4.47%) compared to Australian barramundi (20.0±7.07%) and no mortality was observed in the control without NNV infection. The higher survival rate in barramundi from Situbondo was in line with the blood profile. The number of red blood cell from Situbondo barramundi post-NNV infection (ST) at 96 hpi was higher (P<0.05) than Australian barramundi post-NNV infection (AT). The number of white blood cell of ST at 48 hpi was higher (P<0.05) than AT, but started to decrease at 96 hpi in ST barramundi. The total white blood cell in AT barramundi increased from 48 to 192 hpi. TNFα and IL1-β gene expression levels were significantly higher in the liver, head kidney, and spleen of Situbondo compared to Australian barramundi at 48 hpi, while MHCIIα gene expression in Situbondo’s was significantly higher compared to Australian barramundi at 96 hpi. These results indicate the important roles of all the genes in the barramundi’s immune responses against viral infection. Based on the results of the research, Situbondo’s barramundi has the potential to be used as a candidate for generating broodstock of disease-resistant strain.

Abstract:

Barramundi (Lates calcarifer) is one of the commercial fish in Indonesia. The phenomenon of climate change due to global warming has affected the life of aquatic biota, including fish. The objectives of the present study were to determine a critical thermal maximum (CTMax) and the behavior of Barramundi (L. calcarifer) due to the increase in water temperature. The research was conducted at the Fishing Technology Laboratory, Faculty of Marine and Fisheries, Universitas Syiah Kuala in February 2021. The experiment was conducted in 10 aquariums equipped with heaters. The initial temperature of the treatment was 28oC and increased gradually every one minute by 0.2oC. The results showed that the abnormal behavior of Barramundi fingerling was started to appear at 37oC where the fish began to swim fast, then swim sideways at 38oC-39oC, hit the container wall at 39oC-40oC, jumped and weakened then dead at 40oC and 41oC. The average critical temperature of Barramundi fingerling was recorded at a temperature of 41oC within 65 minutes. Therefore, it is concluded that the Barramundi (L. calcarifer) display an abnormal behavior above the temperature of 35oC, however, they can survive up to 42oC exposure for 70 minutes.Keywords:Critical thermal maximumTemperature riseGlobal warming

Abstract:

Barramundi, L. calcarifer, were collected from seven localities in the Northern Territory, the Daly, Finniss, Mary, Glyde, Roper and McArthur rivers and Blue Mud Bay, and from the Ord River in Western Australia. Barramundi were sampled seven times from the Daly and Finniss rivers over a 14-month period. In total, 46 loci were identified using starch-gel electrophoresis of enzymes and polyacrylamide electrophoresis of muscle proteins. Twelve loci were polymorphic at the P0.99 level. Most loci were in Hardy-Weinberg equilibrium. A contingency Χ2 analysis for homogeneity of alleles over all loci and all localities was highly significant (P < 0.001). Comparisons of data from adjacent pairs of localities revealed that the overall heterogeneity was attributable to heterogeneity among seven of the eight localities; the Daly and Finniss river areas were not significantly different from one another. No evidence of heterogeneity over time was found among the collections from the Daly River area. The considerable amount of heterogeneity observed suggests that each of these seven localities supports a genetically discrete stock of barramundi; this conclusion is consistent with the documented life history of Australian barramundi. The genetic heterogeneity of the stocks should be considered when management policies for L. calcarifer are being formulated.

Abstract:

Larval barramundi in the size range 2.8-5.2 mm were collected from plankton in two estuaries in north-eastern Queensland from 31 October 1979 until 13 February 1980. After leaving the plankton, barramundi moved into nearby brackish and freshwater swamps. These areas acted as nursery grounds, offering both protection from predators, and abundant prey in the form of insect larvae, other fish and crustaceans. These habitats exhibit a wide range of salinities (fresh water-44 × 103 mg l-1) and surface water temperatures (23-36�C). Juvenile barramundi commenced migration from these swamps into permanent tidal creeks around April where they remained for up to 9 months before dispersal into the estuary, up rivers or along coastal foreshores. The diet of the barramundi in these tidal creeks was exclusively fish and crustaceans. Juvenile barramundi were resident in tidal creeks that had been subjected to substantial human interference through habitat alteration. Destruction of nursery swamps may pose a serious threat to local barramundi stocks near centres of human population on the eastern Queensland coast.

Abstract:

Movements of juvenile barramundi resident in tidal creeks of two north-eastern Queensland coastal bays were determined using tag and recapture techniques. In a 3-year period from 1978, 1268 mainly young- of-the-year barramundi were tagged and 213 (17%) recaptured. Most fish were recaptured at the original tagging location, with only 32 (2.5% of all fish tagged) caught away from the tidal creeks where they were released. Marked fish continued to be recaptured within the tidal creeks until they were about 1 year old. Barramundi of this age moved out into the main estuary and dispersed into adjacent streams and coastal habitats. After leaving the tidal creeks, barramundi tagged in Trinity Bay moved an average distance of 7.6 km, whereas those tagged in Rockingham Bay moved an average of 23 km. Factors which may limit the movements of these juvenile fish are discussed.

Abstract:

In 2016, Barramundi, Lates calcaifer juveniles imported from Thailand to the aquaculture station at Sultan Qaboos University exhibited remarkable external clinical signs of losing scales, severe muscle necrosis, and ascites. Fin rot was also observed in the diseased fish. The mortality reached more than 90 % and it was assumed that certain bacterial species were associated with the diseased fish. The objective of the present study was to investigate the infection route of disease, revealing the causative agent and finding the most effective antibiotic treatment. The suspected pathogen vehicle was mosquito larvae in the outlet of the culture tank as bacterium was isolated inside the mosquito larvae. Primary, traditional phenotypic tests and the vitic test confirmed that the bacteria were pathogenic Aeromonas sobria and Lactococcus garvieae. Eight of the most commonly used antibiotics in the aquaculture industry was used for antibiotic susceptibility test. It showed that that Gentamycin was the most effective antibiotic while the most effective environmentally friendly source was henna, Lawsonia inermis, at a concentration of 10%.

Abstract:

AbstractBarramundi (Lates calcarifer) are a highly valued aquaculture species, and, as obligate carnivores, they have a demonstrated preference for dietary protein over lipid or starch to fuel energetic growth demands. In order to investigate how carnivorous fish regulate nutritional cues, we examined the metabolic effects of feeding two isoenergetic diets that contained different proportions of digestible protein or starch energy. Fish fed a high proportion of dietary starch energy had a higher proportion of liver SFA, but showed no change in plasma glucose levels, and few changes in the expression of genes regulating key hepatic metabolic pathways. Decreased activation of the mammalian target of rapamycin growth signalling cascade was consistent with decreased growth performance values. The fractional synthetic rate (lipogenesis), measured by TAG 2H-enrichment using 2H NMR, was significantly higher in barramundi fed with the starch diet compared with the protein diet (0·6 (se 0·1) v. 0·4 (se 0·1) % per d, respectively). Hepatic TAG-bound glycerol synthetic rates were much higher than other closely related fish such as sea bass, but were not significantly different (starch, 2·8 (se 0·3) v. protein, 3·4 (se 0·3) % per d), highlighting the role of glycerol as a metabolic intermediary and high TAG-FA cycling in barramundi. Overall, dietary starch significantly increased hepatic TAG through increased lipogenesis. Compared with other fish, barramundi possess a unique mechanism to metabolise dietary carbohydrates and this knowledge may define ways to improve performance of advanced formulated feeds.

Abstract:

Barramundi (Lates calcarifer) is known as Sea bass with a selling price of Rp.75,000 - Rp.80,000/Kg consumption size. The purpose of this study was to determine the effect of the addition of bread yeast with different doses to feed on the growth of Lates calcarifer. This study uses an experimental method with a Completely Randomized Design (CRD). The treatments were P0=0% yeast, P1=0.5%, P2=0.10%, P3=0.15%, P4=0.20% yeast from the weight of the feed given. The results of the study are the bread yeast influences the growth of Lates calcarifer. The highest absolute weight gain in P4 treatment was 0.507 g. The highest absolute length increase in P4 treatment was 0.990 cm. The lowest FCR at perlakuan P1 yaitu 15,55. The highest survival rates are P2, P3, and P4 which is 100%. Erythrocytes with the highest total amount in P4 treatment 12,58x106 - 18,62x106 cells/mm3. Leukocytes with the highest total number in P2 treatment were 27,96x106 - 44,641x106 cells/mm3. Water quality parameter values in the maintenance media are in the range of requirements for Lates calcarifer cultivation. The conclusion of the study is the addition of bread yeast affects the growth of Lates calcarifer and the optimal dose that can increase the growth is 0,20%.

Abstract:

This paper describes the detection of a polymorphism within the growth hormone (GH) gene of the fish barramundi (Lates calcarifer). PCR amplification of barramundi genomic DNA generated three different sized products: A, 409 bp; B, 478 bp; and H, 520 bp. Each barramundi isolate displayed one of four different types of profiles, which contained specific combinations of these PCR products. Sequence analysis confirmed that products A and B are different forms of the barramundi GH gene, and studies showed that product H was an artifact due to heteroduplex formation between the two smaller-sized molecules. The polymorphic nature of these PCR products was due to differences in the number of repeat monomers within the 5′ end of the barramundi decaminisatellite, an AT-rich repetitive sequence that was identified within intron III of this gene. The barramundi decaminisatellite consisted of 24 or 28 10-nucleotide imperfect direct repeat monomers in a tandem array. The monomers were grouped into one of three different families and evidence for monomer homogenization by crossover fixation was presented. The barramundi decaminisatellite differed from previously reported AT- or GC-rich minisatellites, although a similar decaminisatellite has been identified in intron III of the tilapia GH gene. Key words : mutation, PCR, somatotropin, teleost fish, variable number tandem repeat, VNTR.

Abstract:

The depletion of Australia's wild Barramundi Lates calcarifer fishery pre-empts two future roles for Barramundi aquaculture in Australia: first, the industry is primarily intended to supply meat upon a sustained basis; and second, it will probably serve as the predominant source of genetic material for the augmentation of those wild populations that have been depleted, and in that sense the process becomes somewhat circular and interdependent. This paper considers this relationship in the context of captive gene pool management and suggests an alternative method of conserving Barramundi genetic resources to be used to provide genetically "compatible" stocks for the two activities in conjunction with genetic improvement for commercial operations.

Abstract:

The stocking of predators can have significant consequences on recipient aquatic ecosystems. We investigated some potential ecological impacts of stocking a predatory fish (Lates calcarifer) into a coastal river and a large impoundment in north-eastern Australia. L. calcarifer was mostly found in slower-moving, larger reaches of the river or in the main body of the impoundment where there was abundant suitable habitat. In the tidally influenced freshwater reaches of the coastal river, L. calcarifer predominately consumed aytid and palaemonid shrimp that were associated with local macrophyte beds or littoral grasses. In this area the diets of juvenile stocked and wild L. calcarifer were similar and stocked fish displayed a high degree of site fidelity. Further upstream in the river, away from tidal influence, and in the impoundment, fish were the main prey item. Cannibalism was uncommon and we suggest that, at the current stocking densities, there was little dietary evidence of predatory impacts from L. calcarifer on species of conservation concern. We caution against introducing novel predatory species such as L. calcarifer in or near areas that are outside their natural range and are known to support rare, threatened or endangered species.

Abstract:

In the cultivation of barramundi Lates calcarifer, one of the key factors is developing new commercial feeds that are nutritionally adequate and attractive to fish. The sensory quality of feeds can be improved by taste stimulants. The aim of the present study is to examine the taste attractiveness of 21 free L-amino acids and 4 basic taste substances (0.1–0.001 M). The feeding behavior that accompanied the orosensory testing of feed is also studied. Agar pellets flavored with each taste substance were individually offered to barramundi juveniles (5–9 cm, 4–10 g). Citric acid, cysteine, and alanine were palatable; sucrose and 7 amino acids had an aversive taste; sodium chloride, calcium chloride, and 12 amino acids did not influence the consumption of pellets. Taste preferences for amino acids are positively correlated in 6 out of 21 fish species, which confirms high species specificity of taste preferences in fishes. Barramundi often make repeated grasps and rejections of pellets regardless of their palatability, which led to the destruction of pellets in up to 50% of trials. When swallowing, fish retain pellets several times longer, and pellet fragmentation occurs more often, than in the case of final refusal of pellets. The data presented here can be used to improve the cultivation of barramundi.

Abstract:

Barramundi (Lates calcarifer) is an important marine food fish species in Southeast Asia and Australia. Seventy-four novel microsatellites were isolated from a genomic DNA library enriched for CA repeats and were characterized in 24 unrelated individuals. Among the 74 microsatellites, 71 were polymorphic, with an average allele number of 7.0 ± 3.6/locus. The average expected heterozygosity of these polymorphic markers was 0.66. Sixty-three of the 71 polymorphic microsatellites conformed to Hardy–Weinberg equilibrium. Linkage analyses were conducted in a reference family, leading to the assignment of 34 novel microsatellites and 16 published markers in 16 linkage groups. The novel microsatellites developed in this study will contribute significantly to the construction of a first-generation linkage map for mapping of quantitative trait loci in Barramundi, and supply a large choice of markers for studies on population genetics, stock management, and pedigree reconstruction.Key words: Barramundi, microsatellites, polymorphism, linkage mapping.

Abstract:

Barramundi Lates calcarifer is a high economic value fish in Indonesia and Southeast Asia countries. However, the aquaculture system still experiences problems, including the high cost of production, specifically from feed, which is due to its relatively slow growth and low digestibility. Therefore, this study aims to determine alternative ingredients that can be used in the fish diet to improve feed utilization and growth performance using pumpkin flour Cucurbita moschata. A completely randomized design (CRD) with 6 treatments and 3 replications was adopted in this study. The tested diet was (A) diet without pumpkin flour (control), (B) with 5% (C) 10% (D) 15% (E) 20%, and (F) 25%. The size of the Barramundi samples was 3-4 cm on average and the body weight was 1-3 g at the stocking density of 15 fish/container. The fish fed as much as 10% body weight daily, which is divided into 2 times, namely 08.00 AM and 4.00 PM for 60 days. The results showed that the addition of pumpkin flour had a significant effect on weight gain, daily and specific growth rate, survival, feed efficiency, conversion ratio, and carcass protein (P0.05). The diet with 5% pumpkin flour gave the best results over other treatments, with an average weight gain of 0.761 g, feed conversion of 1.578, feed efficiency of 63.455%, and a daily and specific growth rate of 0.012 g and 0.738%, respectively, The highest carcass protein content was found in the control treatment with a value of 18.210%, which was not significantly different from the 5% pumpkin flour treatment. Therefore, it is concluded that pumpkin flour can be added to the Barramundi diet as much as 5%. Keywords: Barramundi, Snapper, pumpkin, feed utilization

Abstract:

Starch gel electrophoresis of enzymes and polyacrylamide gel electrophoresis of muscle proteins were used to study genetic variation in 589 barramundi from three widely separated regions in northern Australia. Presumed genetic variation was observed at 16 loci (out of 46 screened). However, only 11 of these were polymorphic at the p0.99 level. The average heterozygosity in this species was 0.032. In nearly all cases, genotypic proportions agreed closely with Hardy-Weinberg expectations. Repeated sampling in each region revealed little or no change in allele frequencies over a period of several months. Similarly, comparisons of allele frequencies for fish from marine and from freshwater localities in the south-eastem Gulf of Carpentaria failed to reveal significant genetic differences between habitats. Between-region heterogeneity Χ2 tests indicated substantial genetic differentiation at 10 of the 11I polymorphic loci. These data indicate the existence of at least three distinct stocks or subpopulations of barramundi in Australia.

Abstract:

The sustainable productivity of estuarine fisheries worldwide is threatened by over-fishing, habitat destruction and water impoundment. In some cases, the natural variability of freshwater inputs has been shown to affect catch when low flows reduce nutrient input and inundated nursery habitats. Historically, the annual commercial catch of barramundi (Lates calcarifer) in Queensland has been highly variable for reasons not fully understood. In conjunction with a life-cycle model, statistical analyses of climate variables and barramundi catch data from the Princess Charlotte Bay area identified several significant relationships. Warm sea surface temperatures, high rainfall, increased freshwater flow and low evaporation (all measures of an extensive and productive nursery habitat) were significantly correlated with barramundi catch 2 years later and suggest that young barramundi survival is enhanced under these conditions. Catchability was significantly increased with high freshwater flow and rainfall events in the year of catch. A forward stepwise ridge regression model that included a measure of rainfall and evaporation 2 years before catch explained 62% of the variance in catch adjusted for effort. It is recommended that the impact of climate variability be considered in the management of wild barramundi stocks and possibly other species not yet examined.

Abstract:

Barramundi (Lates calcarifer) often migrate from marine to fresh water as juveniles. In March 2018a relatively large number of small juveniles (<100mm) were recorded moving through a fishway on a tidal interface barrier in central Queensland, Australia. This is in contrast to the few documented observations of transitional movements, which involved mostly larger juveniles (250–400mm).

Abstract:

Barramundi (Lates calcarifer L.) is a predatory fish species native in Southeast Asia and Australia. Based on the geothermal potentiality of Hungary the warm-water fish can be reared successfully. Zooplankton in the wild contains minerals in a higher concentration than the usually fed newly hatched Artemia nauplii, therefore essential trace elements, such as cobalt, zinc and manganese play an important role in the larviculture of barramundi. Cobalt is vital in trace amount for many living functions of vertebrates, however, lower number of papers are available considering the nutritional aspects. Nevertheless. improved growth performance was observed in cases of some fish species when diet was supplemented with CoCl2. Zinc and manganese are also vital for optimal growth and accordingly are investigated and applied diet supplements in aquaculture. The main aim of the recent study is to investigate the effects of cobalt, manganese and zinc on the growth performance and homogeneity of fish when a commercially available dry diet is supplemented with trace elements individually and in combined treatments. A total of 6 treatments were set in a randomized blocked design where the concentrations of the applied elements were 50 mg kg-1 for CoCl2, for ZnSO4 and for MnCl2 individually, as well as for CoCl2 along with ZnSO4 and for CoCl2 along with MnCl2 in combination. Although the production parameters of larval barramundi were positively affected by the addition of trace elements when the retention of minerals occurred through nourishment living organisms, statistically no differences were found between the treatments considering the growth performance of barramundi juveniles either when dry feed was supplemented with cobalt, manganese or zinc (p>0.05). While the use of cobalt and manganese in combined treatments produced a less uniform larvae in size and as a consequence of increased heterogeneity, survival was significantly reduced by the cannibalism, the sizes distribution of barramundi juveniles wasn’t affected by the dry diet supplementation of these elements.

Abstract:

Migration is a fundamental aspect of the life history of many fish and must be well understood for targeted conservation and management. We used acoustic telemetry and otolith 87Sr/86Sr analysis, in conjunction with annual ageing, to study intraspecific variation in barramundi Lates calcarifer migration in the Northern Territory, Australia. Acoustic transmitters were implanted into 25 barramundi (420–1010-mm total length (TL); median 510mm TL) from freshwater reaches of the South Alligator River and their movements tracked over >2 years. 87Sr/86Sr transect analysis was also conducted on otoliths of 67 barramundi from the Daly, Mary, South Alligator and Roper rivers. Acoustic telemetry showed that most fish remained in fresh water across wet and dry seasons. Higher rates of movement occurred during the wet season and a minority of fish moved into the estuary during high flows. Otolith chemistry analyses revealed high diversity in salinity histories among individuals. We integrated the telemetry and otolith chemistry data to examine migration as a function of the stage of sexual development, and have proposed a revised life history model that identifies three migratory contingents. We conclude that anthropogenic disturbance, including modified river hydrology, has the potential to alter the frequency of life history contingents in barramundi populations.

Abstract:

Abstract The effect of nutritional status on IGF-I mRNA expression in the liver and brain of juvenile barramundi (Lates calcarifer) was investigated. Fish were either fed a satiety ration (SAT) or starved (STV) for 6 weeks. Starved fish demonstrated significantly lower condition factor and hepatic IGF-I mRNA expression at 3 and 6 weeks, when compared with the SAT group. IGF-I mRNA expression in the brain was 10 fold lower than the liver and was not affected by ration size. These results suggest the liver is the major site of IGF-I mRNA synthesis and hepatic but not brain IGF-I mRNA expression is regulated by food availability in juvenile barramundi.

Abstract:

Abstract Objectives The aim of this study was to evaluate the synthesis, mechanical strength, and morphology of chitosan–collagen membranes from barramundi scales for guided tissue regeneration technique. Materials and Methods Collagen was extracted from barramundi scales by immersion in acetic acid. The resulting wet collagen was later dried. The membrane was fabricated by mixing chitosan with collagen from barramundi scales. Membrane characterization parameters were measured using Fourier transform infrared (FTIR), scanning electron microscopy (SEM) and mechanical property. Results The FTIR spectrum showed the typical peak of the mixture of chitosan and collagen. The tensile strength and elongation at break of the membrane in dry condition were 0.28 MPa and 8.53%, respectively, while in the wet condition these were 0.12 MPa and 25.6%. The membrane porosity test result was 38.85%; SEM result showed a porous membrane surface with size varying around 16 to 100 µm. Conclusion The chitosan-collagen membrane from the barramundi scale showed the fibrous membrane surface that has ideal porous size as guided tissue regeneration membrane and the lower mechanical strength.

Full text

Abstract:

This investigation showed an ontogenetic shift in the palatability of Bufo marinus tadpoles by measuring consumption of tadpoles at three different developmental stages (newly hatched, intermediate and pre- metamorphic) by an Australian predatory fish, Lates calcarifer (barramundi). A known-palatable tadpole, Limnodynastes ornatus, was used as the control. B. marinus tadpoles at all developmental stages were unpalatable relative to a palatable alternative, with the later stages being the least palatable. Choice experiments further demonstrated that L. calcarifer were able to recognise and choose L. ornatus tadpoles in preference to those of B. marinus. Our experiments demonstrate that at all stages of development, B. marinus tadpoles were unpalatable to L. calcarifer. Contrary to the model proposed by Brodie and Formanowicz (1987), our results suggest an ontogenetic shift in palatability of B. marinus tadpoles to a vertebrate fish predator, with the later stages being less palatable.

Abstract:

Temperature profoundly influences virtually all aspects of fish biology. Barramundi, Lates calcarifer Bloch, 1790, is a catadromous fish that undergoes several migrations in its life cycle, necessitating locomotion under various thermal conditions. The present study examined the effects of varying thermal regimes on performance in juvenile L. calcarifer by determining the effects of rearing and ambient temperature on burst (Umax) and sustained (Ucrit) swimming ability. Fish were incubated at three set temperatures, 26°C (cool), 29°C (control) and 31°C (warm), from egg fertilisation until first feeding before some of the larvae were allocated to different temperatures to differentiate the effects of incubation temperature v. rearing temperature on subsequent swimming performance. Individuals incubated and reared at the cool (26°C) temperature showed significantly faster burst speeds at the 26°C test temperature than fish from any other treatment group. This indicates the ability of L. calcarifer to thermally acclimate burst swimming. However, there was no evidence that incubation temperature (as opposed to rearing temperature) affected burst or sustained swimming ability. Swimming ability was significantly affected by the test temperature, with the Umax of fish highest at the 29°C test temperature. Lower test temperatures depressed both burst and sustained swimming ability. Juvenile L. calcarifer can acclimate Umax, but swimming ability was unaffected by incubation thermal history.

Abstract:

Freshwater farming of barramundi Lates calcarifer in Thailand is a growing sector in aquaculture, but mortalities due to infectious diseases are still a major threat to this industry. In 2018, an episode of severe mortality in juvenile barramundi was noted in a freshwater earth pond site. Fish presented with severe gill necrosis, as well as severe cutaneous hemorrhages, scale loss, and discoloration at the base of dorsal fin (saddleback lesions). Histopathology revealed extensive necrosis of skeletal muscle and gill filaments, as well as basophilic inclusion bodies and megalocytosis in muscle, gill, liver, and kidney. Scale drop disease virus (SDDV) infection was subsequently confirmed by virus-specific semi-nested PCR. Further, DNA sequences of the viral major capsid protein (MCP) and ATPase genes had a respective homology of 99.85 and 99.92% with sequences of SDDV infecting barramundi in saltwater culture. Gill necrosis and saddleback lesions are not typical lesions associated with scale drop syndrome. Their presence was explained by Flavobacterium columnare isolation from the gill, followed by positive F. columnare-specific PCR. To our knowledge, this is the first report of SDDV-associated mortality in freshwater-farmed barramundi. Furthermore, this mortality presented as a concurrent infection with SDDV and F. columnare, with typical lesions of both infections.
