The fatty acid composition of farmed Tra catfish (Pangasius hypophthalmus) was determined and compared to farmed Atlantic salmon (Salmo solar) and to wild-caught Asian seabass (Lates calcarifer). Saturated fatty acids (SFA) were most abundant in catfish (42.6%) while salmon (37.2%) and seabass (39.0%) were rich in polyunsaturated fatty acids (PUFA). Tra catfish contains Docosahexaenoic acid (DH...

Monola oil, a high oleic acid canola cultivar, and canola oil were evaluated as replacers of fish oil at three levels of inclusion (60%, 75% and 90%) in rainbow trout diets. After a 27-week grow-out cycle, the diet-induced effects on growth, fatty acid metabolism and final eating quality were assessed. Overall, no effects were noted for growth, feed utilisation or fish biometry, and the fatty a...

The aim of this study was to determine the effect of different feed restriction periods on the growth performance as well as the biochemical and fatty acid compositions of fillet in rainbow trout (Oncorhynchus mykiss). Fish with an average initial weight of 64.80±7.41g were used in the study. The trial lasted 60 days and 4 different feeding diets were alternately applied to the fish. The contro...

Abstract Pikeperch ( Sander lucioperca ) is a freshwater fish that has become increasingly popular as food fish. Within this study, the influence of spawning process on meat quality was investigated. For purpose, adult pikeperch examined directly before and after spawning, compared regarding physical parameters lipid composition. The results indicate values pH, electrical conductivity yellownes...

Accurate prediction of meat yield in live animals may allow more efficient genetic improvement of meat yield in farm-raised catfish. An initial trial with 30 channel catfish demonstrated significant correlations among weight-adjusted residuals for muscle area measured from transverse ultrasound images and transverse sections at five locations along the trunk musculature (r = 0.30 to 0.70). Rela...

Suboptimal vitamin D status is common among humans, and might increase bone resorption with subsequent negative effects on bone health. Fatty fish, including Atlantic salmon, is an important dietary vitamin D source. However, due to a considerable change in fish feed composition, the contribution of vitamin D from salmon fillet has been reduced. The main objective was to investigate if intake o...

The aim of this study was to develop a simple method for the automatic estimation of fat content in salmon fillets by means of image analysis. Salmon fillets have a zebra-like appearance, consisting of white myocommata stripes divided by red-coloured muscle tissue. The stripes contain a high proportion of lipid, and it has previously been shown that the proportion of myocommata in a fillet corr...

Fish proteins have been reported to be more satiating than meat proteins. The objective was to determine the effect of different animal protein pre-meals on satiety. A total of ten intact female hounds were fed pork loin, beef loin, chicken breast, salmon fillet or pollock fillet. Each pre-meal was fed to contain 100 g protein. Blood was collected at 0, 5, 15, 30, 60, 90 and 120 min postprandia...

the purpose of this study was to investigate the effect of polyvinyl chloride vacuum packaging(170 micron thickness) on omega 3 and omega 6 contents of carp fillet at -18 ° c during 180 day storage. the tests were done with the use of gas chromatography. total content of w6 in fresh fish was 18.21%. after 180 day storage the amount of w6 in control sample changed to 14.85% but for vacuumed fill...

Production traits such as growth, feed efficiency, survival, and fillet yield are economically important traits and an improvement in one or more of these traits will benefit the U.S. catfish farming industry. The U.S. Department of Agriculture (USDA) 103 line of channel catfish was developed jointly between the USDA Agricultural Research Service (ARS) Catfish Genetics Research Unit, Stoneville...
