Studies on animal carotenoids; carotenoids of the brown trout (Salmo trutta Linn.).
This paper presents an analysis of the carotenoids of the brown trout (Salmo trutta Linn.), being the first of a series designed to throw light on the general functions of this class of pigments in animals. Apart from the role of the carotenoid derivative vitamin A as a component of visual purple, and the importance of some carotenes as vitamin A precursors, precise knowledge is almost entirely...
متن کاملMolecular studies on the seasonal occurrence and development of five myxozoans in farmed Salmo trutta L.
Five myxozoan species, Tetracapsuloides bryosalmonae, Sphaerospora truttae, Chloromyxum schurovi, Chloromyxum truttae and a Myxobolus species were detected in farmed brown trout, Salmo trutta L. from Central Scotland. Using PCR and in situ hybridization, this study investigated the seasonal occurrence and tissue location of these species in young of the year brown trout. C. schurovi, C. truttae...
متن کاملEnvironmental stress linked to consumption of maternally derived carotenoids in brown trout embryos (Salmo trutta)
The yellow, orange, or red colors of salmonid eggs are due to maternally derived carotenoids whose functions are not sufficiently understood yet. Here, we studied the significance of naturally acquired carotenoids as maternal environmental effects during embryo development in brown trout (Salmo trutta). We collected eggs from wild females, quantified their egg carotenoid content, fertilized the...
متن کاملComposition of the ovarian fluid in 4 salmonid species: Oncorhynchus mykiss, Salmo trutta f lacustris, Salvelinus alpinus and Hucho hucho.
The ovarian fluid of rainbow trout (Oncorhynchus mykiss), charr (Salvelinus alpinus), lake trout (Salmo trutta f lacustris) and Danube salmon (Hucho hucho) was analyzed for its inorganic and organic composition. The qualitative composition of the ovarian fluid of the investigated species was similar, but significant quantitative differences were found. The following components were determined: ...
متن کاملInfluence of parental life history on maturation and smoltification in brown trout (Salmo trutta L.)
The developmental pathways of the offspring of three groups of trout, Salmo trutta L., with known life histories were compared: one group from a freshwater resident population and two groups from an anadromous population (fish that have smoltified and fish that have not). The fish were hybridized within a group, and 27 families were obtained and reared mixed in two tanks. Tracking fish specimen...
