Unexpected trophic diversity in the endemic fish Orestias chungarensis in a high‐altitude freshwater ecosystem, Lake Chungará (4520 m), northern Chile

Journal of Fish Biology, EarlyView.
Abstract Orestias chungarensis Vila & Pinto, 1986 is a small‐bodied (max fork length = 120 mm) cyprinodontiform fish with a very restricted global distribution. The species is limited to a single, small (283 km2), high‐altitude (4520 m) catchment located in the Altiplano of northern Chile. Until the late 20th century, O.

Dietary administration of vitamin C and Lactobacillus rhamnosus in combination enhanced the growth and innate immune response of the rainbow trout, Oncorhynchus mykiss [PDF]

, 2012
The effects of dietary vitamin C and Lactobacillus rhamnosus on immunity and growth performance were investigated in Oncorhynchus mykiss. For this purpose, 480 rainbow trout (68±5g) were obtained from a local farm and acclimated to laboratory conditions ...

The physiological response of juvenile diploid and triploid Arctic charr Salvelinus alpinus to exhaustive exercise

Journal of Fish Biology, EarlyView.
Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.

Errors in Length-weight Parameters at FishBase.org [PDF]

, 2011
Background: FishBase.org is an on-line database of fish related data that has been cited over 1500 times in the fisheries literature. Length-weight relationships in fish traditionally employ the model, W(L) = aL^b^, where L is length and W is weight ...

Cellular responses to thermal stress and moderate oxygen limitation in juvenile lake trout

Journal of Fish Biology, EarlyView.
Abstract Lake trout (Salvelinus namaycush) is an important food fish in northern communities, inhabiting cool, well‐oxygenated water, but climate change is reducing available habitat, with extended summer stratification of lakes creating an upper thermal barrier (~15°C) and lower dissolved oxygen (DO) boundary (4–7 mg L−1).

Anesthetic effect of tricaine methanesulfonate, clove oil and electroanesthesia on lysozyme activity of Oncorhynchus mykiss [PDF]

, 2011
There is a few available information about the effect of anesthetics, specially electroanesthesia on immune parameters in fish. In the present work, two anesthetics, MS222 (50 ppm), clove oil (25 ppm), and electroanesthesia were tested in rainbow trout ...

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

Journal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

Habitat-based variation in the trophic ecology of the world’s highest-altitude self-sustaining population of invasive rainbow trout

Knowledge and Management of Aquatic Ecosystems
Rainbow trout (Oncorhynchus mykiss) have been widely introduced outside of their natural range and are one of the World’s most invasive species. Illegally introduced into the isolated, high-altitude (4520 m) Chungará catchment of northern Chile, rainbow ...

Study of fish meal substitution with earthworm in diet of rainbow trout (Oncorhynchus mykiss) [PDF]

, 2015
This experiment was carried out to evaluate the effect of earthworm (Eisenia fetida) in diet for rainbow trout in a complete randomized design with 5 treatments in triplicates using 15 cages in a pound for 8 weeks.
