Abstract:
... To examine the effects of dietary lipids on the growth and feed utilization of jade perch juveniles, Scortum barcoo, diets containing 36.3% crude protein supplemented with increasing lipid levels (6, 9, 12, and 15% of the dry matter) were used to feed triplicate groups of 30 fish for 60 d. At the end of the experiment, more than 95% fish survived well from all diet groups (P > 0.05). Measurements ...
... The bacterial community structure associated with filter materials in the recirculating aquaculture system of Scortum barcoo was investigated using the 16S rRNA gene clone library method. Preliminary results showed that the clone library constructed from the initial operation condition was characterized by 31 taxa of bacteria belonging to eight phyla including Proteobacteria, Acidobacteria, Firmic ...
... The aim of this study was to test and evaluate a 2D computer vision technique that estimates the mass of Jade perch Scortum barcoo swimming freely in a tank of a recirculation aquaculture system. The first step of this study, which is described in this paper, was to build up a relationship between the fish shape and its mass in order to be able to estimate the mass of the fish by vision techniques ...
... The first days of exogenous feeding are crucial for larval recruitment. A correct first prey item and the determination of the optimal weaning age, can reduce labor cost and fish mortality to a great extent. This study was conducted to evaluate the use of small and regular Artemia fransiscana (AF and EG Artemia, Inve, Belgium) as first feed for jade perch Scortum barcoo, and to determine the minim ...

Abstract:
... A 10‐week trial was conducted to determine the response of juvenile jade perch Scortum barcoo on the replacement of dietary fish oil (FO) in a fishmeal free diet. Three iso‐nitrogenous, isocaloric and isolipidic diets were formulated, each containing a different primary fat source: FO, linseed oil (LO), and a mixture of Schizochytrium and LO. The substitution of FO with the mixture of Schizochytri ...
... Jade Perch Scortum barcoo having an initial average weight of 7.28 ± 0.13 g (mean ± SE) were cultured in a recirculating system at different feeding frequencies that included one, two, three, or four meals a day at 5% body weight per day. Treatments were performed in triplicate using 65 fish in each replicate. After 72 d, the survival, growth, feeding efficiencies, body indices, plasma biochemistr ...
... Nocardiosis is a chronic infectious disease that afflicts multiple fish species and poses a growing threat to the aquaculture. In this study, Nocardia sp. infection was identified in jade perch, Scortum barcoo, from a pond culture in Guangzhou, China. The infected fish were characterized by dark body color, occasional skin ulcerations, and nodular lesions in the kidney, liver, heart, and other org ...
... In 2013, an outbreak of ulcerative disease associated with ranavirus infection occurred in barcoo grunter, Scortum barcoo (McCulloch & Waite), farms in Thailand. Affected fish exhibited extensive haemorrhage and ulceration on skin and muscle. Microscopically, the widespread haemorrhagic ulceration and necrosis were noted in gill, spleen and kidney with the presence of intracytoplasmic eosinophilic ...

Abstract:
... Food waste is a low-cost and nutritious source of feed which could be beneficial to the fishery industry. The objective of this study was to use fermented food wastes as major sources of protein to replace the fish meal used in fish feeds for culturing jade perch (Scortum barcoo) and Nile tilapia (Oreochromis niloticus). Two experiments (a laboratory and a field trial) were conducted to test the s ...

Abstract:
... A 150‐days study was conducted on the continuous exposure of magnetized water at 0.00, 0.10, 0.15 and 0.20 Tesla (T) on quadruplicate treatments of Jade Perch Scortum barcoo juveniles in a recirculating system. Each replicate consisted of 18 fish with an average weight of 7.52 g over all treatments. The feeding efficiencies, growth, whole‐body proximate plasma parameters, survival were measured an ...
... Recirculating aquaculture systems (RAS) using biofloc biofilters can address the high accumulation of nitrate (NO₃⁻-N) and total suspended solids (TSS) in in-situ biofloc technology (BFT) aquaculture systems. A RAS was divided into the following four zones: reaction zones of the BFT biofilters, settling zones of the BFT biofilters, culture tanks, and a buffer tank. During the 95-day experimental p ...

Abstract:
... Two farmed freshwater fish species Nile tilapia (Oreochromis niloticus) and jade perch (Scortum barcoo) were cultured with food waste-based diets and compared with commercial formulated control diet for a period of six months. Sixteen priority polycyclic aromatic hydrocarbons (PAHs) in the diets and cultured fish meat were tested by gas chromatography–mass spectrometry. No significant differences ...
... Proteins related to antioxidant defence systems and energy maintenance play a vital role in resisting starvation in fish. However, studies on the underlying molecular mechanism of starvation stress in the jade perch Scortum barcoo are very limited. Thus, the proteomic changes in S. barcoo during fasting were investigated by stable isotope labelling and high‐performance liquid chromatography‐tandem ...

Abstract:
... To achieve high water-treatment efficiencies and simplify the setup of recirculating aquaculture systems (RAS), this study examined the use of suspended growth reactors (R1 and R2) based on biofloc technology (BFT) as water-treatment biofilters. Moreover, the conversion of the heterotrophic R1 biofilter to a nitrifying role was investigated. During RAS operation using heterotrophic BFT biofilters, ...

Abstract:
... Jade perch (Scortum barcoo) is a new teleost in the developing aquaculture freshwater finfish grow-out sector in Australia and China. However, key information on the breeding sex determination system (SDS) remains poorly understood, hampering sex control programs and genetic improvement. In this study, the jade perch SDS was examined by investigating genome-wide single-nucleotide polymorphisms (SN ...
