Exposure of prawns to dark- or light-coloured substrates is known trigger a strong colour adaptation response through expansion contraction the colouration structures in prawn hypodermis. Despite difference triggered by this adaptive response, total levels predominant carotenoid pigment, astaxanthin, are not modified, suggesting that another mechanism regulating phenomenon. Astaxanthin binds specific protein called crustacyanin (CRCN), and it interaction between quantities each these...
The black tiger shrimp (Penaeus monodon) remains the second most widely cultured species globally; however, issues with disease and domestication have seen production levels stagnate over past two decades. To help identify innovative solutions needed to resolve bottlenecks hampering culture of this species, it is important generate genetic genomic resources. Towards aim, we produced complete publicly available P. monodon transcriptome database date based on nine adult tissues eight early...
The contribution of epiphytes associated with physical substrates to the nutritional requirements post-larval shrimp, Penaeus esculentus Haswell, was determined in high-density rearing systems (3000, 6000 and 11 000 m−3). Stable isotope signatures on polyethylene mesh substrate, AquaMats™ tank walls were compared shrimp signatures. Two methods used: determination carbon nitrogen natural abundance ratios; 15N-nitrogen enrichment ratios after addition 15N-ammonium tanks. Using technique a...
SUMMARY Myostatin (MSTN) and growth differentiation factor-11 (GDF11) are closely related proteins involved in muscle cell as well neurogenesis of vertebrates. Both MSTN GDF11 negatively regulate their functions. Invertebrates possess a single ortholog the MSTN/GDF11 family. In order to understand role crustaceans, gene was identified characterized penaeid shrimp Penaeus monodon. The overall protein sequence specific functional sites were highly conserved with other members Gene transcripts...
Custom-built single-nucleotide-polymorphism (SNP) marker systems that are compatible with Sequenom® chemistry compared a general purpose microsatellite system in their ability to accurately assign Black Tiger shrimp parentage. The consisted of 13 markers, while the SNP comprised 63 (SNPa), 59 (SNPb) or 122 markers (SNPab). Comparisons were made using animals from commercial breeding lines thresholds for assignment derived simulated genotypes. Pedigree was highest when panel SNPab used. Panel...
Rotaviruses (RV) have a high prevalence in piggeries worldwide and are one of the major pathogens causing severe diarrhoea young pigs. RV species A, B, C been linked to piglet Australian pig herds, but their genetic diversity has not studied detail. Based on sequencing structural viral protein 7 (VP7) RVA G genotypes G3, G4 G5, RVC types G1, G6 identified previous studies. Although occurrence RVB was reported Australia 1988, no further analysis conducted. To improve health management...
Gill-associated virus (GAV) is a nidovirus that commonly infects Penaeus monodon (black tiger shrimp) in eastern Australia, causing morbidity and mortalities the acute stage of disease. Here we explored possibility inhibiting GAV replication disease using double-stranded (ds)RNAs expressed bacteria delivered either orally or by muscle injection. To enhance potential RNA interference (RNAi) responses, 5 long dsRNAs were used targeted open reading frame 1a/1b (ORF1a/b) gene regions thus only...
Abstract Background Restrictions to gene flow, genetic drift, and divergent selection associated with different environments are significant drivers of differentiation. The black tiger shrimp ( Penaeus monodon ), is widely distributed throughout the Indian Pacific Oceans including along western, northern eastern coastline Australia, where it an important aquaculture fishery species. Understanding structure influence environmental factors leading adaptive differences among populations this...
Abstract Background The development of genome-wide genotyping resources has provided terrestrial livestock and crop industries with the unique ability to accurately assess genomic relationships between individuals, uncover genetic architecture commercial traits, as well identify superior individuals for selection based on their specific profile. Utilising recent advancements in de-novo technologies, it is now possible provide aquaculture these same important resources, even absence existing...
A previous study suggested that mesendoderm (ME) cell arrest occurred at the 64‐cell stage and a ring of eight presumptive naupliar mesoderm cells or crown surrounded blastopore in Kuruma shrimp Penaeus (Marsupenaeus) japonicus. Since this varied from pattern observed other penaeoidean shrimp, cleavage gastrulation was re‐examined P. japonicus using nucleic acid stain Sytox Green confocal microscopy. In contrast to earlier study, followed shrimp. The ME arrested 32‐cell stage, ingressed into...
The ability of Novacq to improve resilience black tiger shrimp, Penaeus monodon , infection and mortality induced by gill‐associated virus ( GAV ) was investigated. Over a 26‐d period, shrimp were fed pellets with or without 10% Novacq. Following this, four replicate tanks, each containing 10 that had been either diet, maintained as‐is, injected saline inoculum (i.e., 40 for the six groups). For n = 20) in two group survival monitored daily over 14 d pleopod sampled from on Days 0 14. other...
Advances in the domestication and selective breeding of Australian Black Tiger shrimp, Penaeus monodon, opens opportunity for world producers to reconsider benefits farming this species. Just over a decade ago species was world's most farmed shrimp species, however, difficulty its domestication, part, led widespread establishment vannamei (Pacific White shrimp) as world. This study empirically evaluates productivity commercially domesticating P. monodon against production from wild...
Abstract Shrimp are a valuable aquaculture species globally; however, disease remains major hindrance to shrimp sustainability and growth. Mechanisms mediated by endogenous viral elements have been proposed as means which that encounter new virus start accommodate rather than succumb infection over time. However, evidence on the nature of such how they mediate accommodation is limited. More extensive genomic data Penaeid from different geographical locations should assist in exposing...
