In Streptococcus iniae, lactate metabolism is dependent upon two proteins, lactate permease that mediates uptake and lactate oxidase, a flavin mononucleotide-dependent enzyme that catalyzes oxidation of alpha-hydroxyacids. A novel variant of the lactate oxidase gene, lctO, in Australian isolates of S. iniae from diseased barramundi was found during a diagnostic screen using LOX-1 and LOX-2 prim...
Identification of differentially expressed genes (DEGs) and regulated pathways in response to stressors using a whole-genome approach is critical to understanding the mechanisms underlying stress responses. We challenged Asian seabass with lipopolysaccharide (LPS), Vibrio harveyi, high salinity and fasting, and sequenced six cDNA libraries of intestine samples using Roche 454 RNA-seq. Over 1 mi...
BACKGROUND The Asian seabass (Lates calcarifer) is a protandrous hermaphrodite that typically matures as a male at approximately 2-4 years of age and then changes sex in subsequent years. Although several sexual maturation stages have been described histologically for both testis and ovary, the underlying gene expression profiles remain lacking. The development of a gene expression platform is ...
The age of whole otoliths from barramundi (Lates calcarifer) obtained the southern Gulf Carpentaria were estimated using Fourier transform near-infrared (FT-NIR) spectroscopy. Otoliths 1716 collected in 2006, 2009 and 2012–2015 used this study. Partial least-squares regression models (PLS-R) multiple linear (MLR) developed diffuse reflectance spectra was traditional sectioned otoliths. Calibrat...
Asian seabass (Lates calcarifer) is a food fish of increasing aquaculture importance. In order to improve our understanding on the digestive system and feeding of this species, morphological and histological features of the gut were studied. Morphologically, the Asian seabass gut is defined by a short and muscular esophagus, well-developed stomach and comparatively short intestine. Mucous secre...
As nutrition-related expenses constitute the majority of the costs for aquaculture farms, it is essential for them to use feeds that provide an ideal combination of nutrients for the species of choice. In this study, the relative effect of consuming three different pelleted feeds (B, C and D) in comparison to frozen baitfish (A; control) were compared on juvenile Asian seabass (77.3 ± 22.4g) th...
Barramundi skin, a by-product of the fish processing industry, has shown potential as an alternative collagen source. However, commonly used acid extraction method to produce rendered low yield requires lengthy time and is not environmentally friendly. As result, adoption greener technology, such ultrasound, improve conventional process emerging. This study aimed investigate effect different ul...
ویبریو هاروی به عنوان بخشی از فلور رودهی ماهیان دریایی گوشتخوار، یکی از عوامل اصلی ایجاد بیماری ویبریوز ماهی باس دریایی آسیایی در بسیاری از مزارع پرورش در قفس در دنیا محسوب میشود. هدف از این مطالعه، بررسی نقش این باکتری در تلفات ماهی باس دریایی آسیایی در مناطق جنوبی کشور بود. در این مطالعه در بررسی 11 مورد تلفات ماهی باس دریایی آسیایی پرورشی، تعداد 110 قطعه ماهی (80 قطعه ماهی ب...
