Abstract	This study investigated the effects of different temperatures on the performance, composition, and nutrient retention of Chinook salmon reared in freshwater. Individuals (187.6 ± 27.1 g) were distributed into twelve tanks of 8000 L each (155 to 157 fish per tank) at a temperature of 14 °C. The tanks were transitioned from 14 °C (hatchery temperature) to 8, 12, 16, and 20 °C over seven days. Three fish assessments were performed, the first (initial) when the fish were distributed in the tanks, a second (interim) between days 9 and 16 at the start of the experiment, and a third (final) after 41 to 49 days at the target temperature. At the end of the trial, performance parameters, proximate composition, amino acid, and fatty acid composition, and nutrient retention were evaluated. Better growth performance was observed in fish at 16 °C and 20 °C compared to the lower temperatures. Fish at higher temperatures had higher levels of saturated fatty acids (SFA), while at lower temperatures fish had higher levels of n-3 and n-6 polyunsaturated fatty acids (PUFA), especially eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). A polynomial relationship between nutrient retention and temperature showed that fish from all treatments retained more lipids than proteins, with higher retention of MUFA compared to the other fatty acid classes. Additionally, DHA retention was approximately three times higher than EPA retention. The results showed that 16 to 20 °C was the optimum temperature range for Chinook salmon, and the performance differences were mainly modulated by lipid retention/catabolism.

Abstract	Chinook salmon (Oncorhynchus tshawytscha), also referred to as King salmon, is a premium aquaculture species farmed in New Zealand and to a small extent in western Canada. Despite the high research investment in the 50s and 60s, literature on nutrition on chinook salmon from recent years is sparse, particularly when compared to other salmonid aquaculture species, such as Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss). To improve fish productivity, it is essential to provide specific and efficient diets based on satisfying chinook salmon requirements for nutrients and energy and adapting these to life-stage, season, and production variables. Diet specifications for chinook salmon have to date largely been based on knowledge derived from other salmonid species and may not be optimised for chinook salmon. Thus, there is a lack of knowledge in some fundamental areas. This review explores the production status and literature related to the macro and micronutrient requirements, and general nutrition of chinook salmon. In doing so it compares these requirements to other farmed salmonids to understand some of the differences between species and highlights the main gaps in the literature.

Abstract	We investigated the effects of temperature and fasting on chinook salmon (Oncorhynchus tshawytscha) at different life stages. In the first stage, fish were reared at 13 °C (198.5 ± 34.6 g) or 17 °C (218.3 ± 47.6 g) and fasted for 27 and 26 days, respectively. In the second stage, fish reared at 13 °C (481.8 ± 54.3 g) and 17 °C (597.3 ± 64.3 g) were fasted for 42 and 41 days respectively. At the third stage, fish were reared only at 17 °C (1065.7 ± 190.9 g) and fasted for 42 days. At the end of each fasting period performance, fillet and whole-body proximal composition, and whole-body fatty acid profile were compared among fish before and after fasting. Additionally, fillet fatty acid daily loss was compared in fasted fish from different treatments. The results showed that body weight was not significantly impacted by fasting. However, at 17 °C fasting at all three stages had a negative impact on fillet weight and total fatty acid daily loss. With few exceptions, saturated (SFA), monounsaturated (MUFA) and polyunsaturated fatty acids from n-6 series (n-6 PUFA) were preserved in fillet of fish at 17 °C, while higher daily losses of docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and consequently polyunsaturated from n-3 series (n-3 PUFA) were observed in these same fish and in smaller fish at 13 °C. The results presented in this study provide important information regarding the influence of fasting and temperature on chinook salmon performance and metabolism, providing basis for future nutritional and compositional studies for this important commercial species.

Abstract	The objective of this study was to develop a nutrient-demand model for King salmon (Oncorhynchus tshawytscha) based on a factorial nutrient demand approach. Growth potential was defined using laboratory data to define the thermal response boundaries and benchmarked against commercial farm-data. These factors were combined to determine the size specific mass-gain of the animal across its production cycle. Algorithms of body composition across the size ranges for this species were defined based on the analysis of whole-body samples across the size range from 110 g/fish to 4786 g/fish. The utilisation efficiencies and maintenance demand for protein (46%) and energy (66%) were determined. Each of these factors were then assembled into a model that allowed the iterative estimation of macronutrient specifications of diets, based on intake being driven by the demands for energy. Demands for essential amino acids, and how these demands change with animal size, were predicted by applying the ideal protein concept to protein gain and maintenance, combined with estimates of variable utilisation efficiencies of individual amino acids. Modelled estimations of energy and protein demands were slightly higher than most of the empirical data, with the model suggesting that a higher dietary level of protein, relative to other salmonid diets, has potential benefits for King salmon.

Abstract	We investigated the effects of temperature and fasting on chinook salmon (Oncorhynchus tshawytscha) at different life stages. In the first stage, fish were reared at 13 °C (198.5 ± 34.6 g) or 17 °C (218.3 ± 47.6 g) and fasted for 27 and 26 days, respectively. In the second stage, fish reared at 13 °C (481.8 ± 54.3 g) and 17 °C (597.3 ± 64.3 g) were fasted for 42 and 41 days respectively. At the third stage, fish were reared only at 17 °C (1065.7 ± 190.9 g) and fasted for 42 days. At the end of each fasting period performance, fillet and whole-body proximal composition, and whole-body fatty acid profile were compared among fish before and after fasting.

Abstract: The effect of feeding restricted rations was investigated in two different size classes of Chinook (King) salmon (Oncorhynchus tshawytscha). Smaller individuals (725 g initial mean weight) were fed with 100% (satiation, SR1), 90.4% (SR2), or 81.6% (SR3) ... ...

Abstract	The effect of feeding restricted rations was investigated in two different size classes of Chinook (King) salmon (Oncorhynchus tshawytscha). Smaller individuals (725 g initial mean weight) were fed with 100% (satiation, SR1), 90.4% (SR2), or 81.6% (SR3) feed rations for 64 days, while larger individuals (1689 g initial mean weight) were fed with 100% (LR1), 82.6% (LR2), or 76.1% (LR3) feed rations for 119 days. The growth performance was evaluated for both size classes, and for the larger individuals, the analysis also included spinal curvature incidence (lordosis–kyphosis–scoliosis (LKS)), whole-body and fillet proximate composition, and fatty acid profiles. In both size classes, the final weight, weight gain, specific growth rate (SGR), and condition factor (CF) were significantly higher in individuals fed to satiation (SR1 and LR1) compared to individuals fed restricted rations (SR2 and LR2, SR3 and LR3). However, no significant differences in FCR were observed among the different treatments. Although the incidence of spinal curvature and vertebral body anomalies (i.e., compressions, fusions, vertical shifts) in the larger individuals were higher for the groups fed to satiation (LR1) compared to the groups fed restricted rations (LR2 and LR3), only the differences in vertebral anomalies were statistically significant. No significant differences were observed in whole-body and fillet proximate composition, while several significant differences were observed in the fatty acid profiles (whole-body and fillet) of larger individuals fed different rations. Monounsaturated fatty acids (MUFA), especially oleic acid (OA, 18:1n-9), and n-6 polyunsaturated fatty acids (n-6 PUFA), especially linoleic acid (LA, 18:2n-6) levels, were higher in fish fed to satiation. In contrast, saturated (SFA), primarily palmitic acid (PA, 16:0), and n-3 polyunsaturated fatty acids (n-3 PUFA), primarily eicosapentaenoic acid (EPA, 20:5n-3), and docosahexaenoic acid (DHA, 22:6n-3), were lower in groups fed the higher rations. Despite the overall improved growth performance of the groups fed to satiation, our results suggest that feeding Chinook salmon restricted rations has the potential to decrease the incidence of spinal anomalies, particularly vertebral body anomalies, and improve product quality (based on n-3 PUFA levels), without compromising FCR.

Abstract	We used transcriptome sequencing to investigate the hepatic postprandial responses of Rachycentron canadum (cobia), an important commercial fish species. In total, 150 cobia juveniles (50 per tank, triplicate) were fed ad libitum with a commercial diet for 7 days, fasted for 24 h, and fed for 10 min. The liver was sampled 10 min prior to feeding and 30 min, 1, 2, 4, 8, 12, and 24 h after the feeding event. Each sample was evaluated in terms of liver fatty acid profile and gene expression. Differential gene expressions were evaluated, focusing on fatty acid synthesis and oxidation pathways. In general, the liver fatty acid profile reflected diet composition. Docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and n-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) levels increased at 8 to 12 h but decreased at 24 h after the feeding event. A high number of differentially expressed genes (DEGs) were observed comparing fish that fasted for 8 h with those fasted for 30 min and 24 h, while a reduced number of DEGs was observed comparing individuals who fasted for 30 min compared with those who fasted for 24 h. Similarly, the main differences in the expression of genes related to the fatty acid biosynthesis and oxidation pathways were noticed in individuals who fasted for 8 h compared with those who fasted for 30 min and 24 h. The results suggested that the adequate time to sample the individuals ranged between 8 and 12 h after the meal since, apparently, after 24 h, differential gene expression was not necessarily influenced by food intake.

Abstract	Cobia (Rachycentron canadum) is a marine teleost species with great productive potential worldwide. However, the genomic information currently available for this species in public databases is limited. Such lack of information hinders gene expression assessments that might bring forward novel insights into the physiology, ecology, evolution, and genetics of this potential aquaculture species. In this study, we report the first de novo transcriptome assembly of R. canadum liver, improving the availability of novel gene sequences for this species. Illumina sequencing of liver transcripts generated 1,761,965,794 raw reads, which were filtered into 1,652,319,304 high-quality reads. De novo assembly resulted in 101,789 unigenes and 163,096 isoforms, with an average length of 950.61 and 1,617.34 nt, respectively. Moreover, we found that 126,013 of these transcripts bear potentially coding sequences, and 125,993 of these elements (77.3%) correspond to functionally annotated genes found in six different databases. We also identified 701 putative ncRNA and 35,414 putative lncRNA. Interestingly, homologues for 410 of these putative lncRNAs have already been observed in previous analyses with Danio rerio, Lates calcarifer, Seriola lalandi dorsalis, Seriola dumerili, or Echeneis naucrates. Finally, we identified 7894 microsatellites related to cobia’s putative lncRNAs. Thus, the information derived from the transcriptome assembly described herein will likely assist future nutrigenomics and breeding programs involving this important fish farming species.
