(2008). The effects of the acetic acid " pain " test on feeding, swimming, and respiratory responses of rainbow trout (Oncorhynchus mykiss).

Gonadotropins (GTHs), FSH and LH, play central roles in vertebrate reproduction. Here, we report the production of biologically-active recombinant FSH (r-mtFSH) and LH (r-mtLH) of an endangered salmon species, Manchurian trout (Brachymystax lenok), by baculovirus in silkworm (Bombyx mori) larvae. The biological activities of the recombinant hormones were analyzed using COS-7 cell line transient...

Unidirectional (36)Cl(-) efflux via the red blood cell anion exchanger was measured under Cl(-) self-exchange conditions (i.e. no net flow of anions) in rainbow trout Oncorhynchus mykiss and red-eared freshwater turtle Trachemys scripta to examine the effects of acute temperature changes and acclimation temperature on this process. We also evaluated the possible adaptation of anion exchange to ...

Cobalamin uptake and transport in mammals are mediated by three cobalamin-binding proteins: haptocorrin, intrinsic factor, and transcobalamin. The nature of cobalamin-binding proteins in lower vertebrates remains to be elucidated. The aim of this study was to characterize the cobalamin-binding proteins of the rainbow trout (Oncorhynchus mykiss) and to compare their properties with those of the ...

Flavobacterium psychrophilum is the causative agent of rainbow trout fry syndrome (RTFS), also called bacterial cold water disease (BCWD) in USA. Since being discovered in USA in the 1940s, the disease has spread to aquacultures worldwide [1]. Mortality rates as high as 90% have been reported in fry, although the mortality rate in Danish outbreaks average around 30–40%. Rainbow trout (Oncorhync...

An Evaluation of Stress Induced Hortality of Stocked Catchable-sized Rainbow Trout in Temple Fork of the Logan River

Endotoxins from Escherichia coli and Aeromonas salmonicida caused marked cortisol production in the rainbow trout (Salmo gairdneri).

From the large data set available on the toxicity of boron to aquatic organisms, the toxicity of boron to the early life stages of rainbow trout (Oncorhyncus mykiss) is the seminal issue relative to setting water quality criteria and effluent standards. Issues associated with the early life stage studies are the flat concentration-response curve, the low threshold of toxicity, and teratogenic e...

Movement of live animals is a key contributor to disease spread. Farmed Atlantic salmon Salmo salar, rainbow trout Onchorynchus mykiss and brown/sea trout Salmo trutta are initially raised in freshwater (FW) farms; all the salmon and some of the trout are subsequently moved to seawater (SW) farms. Frequently, fish are moved between farms during their FW stage and sometimes during their SW stage...
