Biochemical composition of copepods for evaluation of feed quality in production of juvenile marine fish
(Journal article; Peer reviewed, 2007-12-13)To increase current knowledge on the nutritional value of natural prey organisms, the biochemical components of mainly three copepods (Acartia grani, Centropages hamatus, and Eurytemora affinis) from a marine pond system ... -
The combined impact of plant-derived dietary ingredients and acute stress on the intestinal arachidonic acid cascade in Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2010-03)A study was conducted to assess the effect of substituting high levels of dietary fish oil (FO) and fishmeal (FM) for vegetable oil (VO) and plant protein (PP) on the intestinal arachidonic acid (AA) cascade in the carnivorous ... -
Different Dietary Levels of Protein to Lipid Ratio Affected Digestive Efficiency, Skeletal Growth, and Muscle Protein in Rainbow Trout Families
(Journal article; Peer reviewed, 2009)Normal Protein (NP) and High Protein (HP) diets were provided to rainbow trout families from juvenile to maturity. Muscle protein concentration increased during growth and the protein to lipid (P/L) ratio was doubled at ... -
Effects of different modified diets on growth, digestive enzyme activities and muscle compositions in juvenile Siamese fighting fish (Betta splendens Regan, 1910)
(Journal article; Peer reviewed, 2011-10-12)The effects of four modified diets (gamma-irradiated, microwave-irradiated, probiotic-supplemented and carbohydrase-supplemented diets) were studied on digestive enzyme specific activities and growth performance quality ... -
Effects of ration on the maturation and fecundity in captive Atlantic herring (Clupea harengus)
(Journal article; Peer reviewed, 1998)We examined the effects of amount of food on vitellogenic oocyte size and number (fecundity) between two experimental groups of Atlantic herring (Clupea harengus) kept in separate but identical compartments of a large ... -
Molecular cloning, characterization and nutritional regulation of key enzymes required for the effective utilization of marine wax esters by Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2010-10)Previous studies had shown that wax ester-rich lipid extracted from calanoid copepods could be a useful alternative to fish oil as a provider of long-chain n-3 polyunsaturated fatty acids in diets for use in salmon ... -
Seasonal variability in nutrient regeneration by mussel Mytilus edulis rope culture in oligotrophic systems
(Journal article; Peer reviewed, 2011-06-09)Blue mussel Mytilus edulis cultures contribute to nutrient cycling in coastal ecosystems. Mussel populations filter particulate nutrients from the water column and inorganic nutrients are regenerated by excretion of metabolic ...
