Many studies have evaluated the adequacy of alternate ingredient diets for Atlantic salmon, Salmo salar, mainly with focus on fish performance and health; however, comprehensive analysis of fillet quality is lacking, particularly for salmon fed these diets in recirculation aquaculture systems (RAS). To this end, a study was conducted comparing fillet quality and processing attributes of postsmolt Atlantic salmon fed a fishmeal-free diet (FMF) versus a standard fishmeal-based diet, in replicate R...

AbstractGenetic line-by-environment (G×E) interactions were determined for growth and processing traits of five genetic lines of Rainbow Trout Oncorhynchus mykiss reared in four environments. Genetic lines included (1) a mixed pool of 109 families selectively bred for improved growth (Growth Line) at the U.S. Department of Agriculture (USDA) National Center for Cool and Cold Water Aquaculture (NCCCWA; Kearneysville, West Virginia), (2) a mixed pool of 52 randomly bred families (Synthetic Control...

Fillet yield (FY, %) is an economically-important trait in rainbow trout aquaculture that affects production efficiency. Despite that, FY has received little attention in breeding programs because it is difficult to measure on a large number of fish and cannot be directly measured on breeding candidates. The recent development of a high-density SNP array for rainbow trout has provided the needed tool for studying the underlying genetic architecture of this trait. A genome-wide association study ...

The Atlantic salmon farming industry has progressively decreased the proportion of fishmeal used in commercial diets due to rising costs and sustainability concerns. A variety of alternate proteins have been identified to partially replace fishmeal; however, very little research has described the effect of feeding alternate protein, fishmeal-free diets to Atlantic salmon, particularly post-smolts cultured in recirculation aquaculture systems (RAS). Therefore, a 6-month study was conducted to com...

AbstractFemale Rainbow Trout Oncorhynchus mykiss were cultured within a freshwater recirculating aquaculture system under 24-h constant lighting in 13°C water and fed every 6 h to near satiation. An opaque roof allowed surface light intensity to vary between <200 and about 1,500 lx. During months 14–26 posthatch we examined changes in plasma concentrations of testosterone (T), estradiol-17β (E2), the maturation inducing steroid (MIS) 17α,20β-dihydroxy-4-pregnen-3-one (17,20βP), growth hormone (G...

Sexual maturation occurs at the expense of stored energy and nutrients, including lipids; however, little is known regarding sex effects on nutrient regulatory mechanisms in rainbow trout prior to maturity. Thirty-two, 14-month-old, male and female rainbow trout were sampled for growth, carcass yield, fillet composition, and gene expression of liver, white muscle, and visceral adipose tissue. Growth parameters, including gonadosomatic index, were not affected by sex. Females had higher percent s...

Abstract To study the effects of sexual maturation on fatty acid metabolism in fish fed to satiation daily, expression of thirty-five genes involved in fatty acid metabolism was determined in sexually maturing diploid (2N; fertile) and triploid (3N; sterile) female rainbow trout. Gene expression was assessed in liver, white muscle, and visceral adipose tissues for fish that were 16 to 24 M of age. Previously, we reported minimal differences in most growth measurements between maturing 2N and 3N ...

Abstract In many cultured fish species, such as salmonids, gonadal development occurs at the expense of stored energy and nutrients, including lipids. However, mechanisms regulating nutrient repartitioning during sexual maturation are not well understood. This study compared sexually maturing diploid (2 N) and sterile triploid (3 N) female rainbow trout to investigate effects of sexual maturation on expression of 35 genes involved in fatty acid metabolism, including genes within fatty acid synth...

AbstractDuring a controlled 6-month study using six replicated water recirculation aquaculture systems (WRASs), it was observed that Rainbow Trout Oncorhynchus mykiss in all WRASs exhibited a higher-than-normal prevalence of side swimming (i.e., controlled, forward swimming but with misaligned orientation such that the fish's sagittal axis is approximately parallel to the horizontal plane). To further our understanding of this abnormality, a substudy was conducted wherein side swimmers and norma...
