(Submitter supplied) Background: Salmonid species have followed markedly divergent evolutionary trajectories in their interactions with sea lice. While sea lice parasitism poses significant economic, environmental, and animal welfare challenges for Atlantic salmon (Salmo salar) aquaculture, coho salmon (Oncorhynchus kisutch) exhibit near-complete resistance to sea lice, achieved through a potent epithelial hyperplasia response leading to rapid louse detachment. more...

(Submitter supplied) There is a paucity of information on the physiological changes that occur over the course of salmon early marine migration. Here we aim to provide insight on juvenile Coho salmon (Oncorhynchus kisutch) physiology using the changes in gene expression (cGRASP 44K microarray) of four tissues (brain, gill, muscle, and liver) across the parr to smolt transition in freshwater and through the first eight months of ocean residence. more...

(Submitter supplied) Most Pacific salmonids undergo smoltification and transition from freshwater to saltwater. Saltwater acclimation requires salmonids to make various adjustments in color, shape, size, metabolism, catabolism, and osmotic and ion regulation. The molecular mechanisms underlying this transition are largely unknown. The present study acclimated coho salmon (Oncorhynchus kisutch) to four different salinities (<0.5, 8, 16, and 32 ppth) and assessed gene expression through microarray analysis of gill, liver and olfactory tissues. more...

(Submitter supplied) Exposure to environmental concentrations of organophosphate pesticides in Pacific salmon can cause neurobehavioral injuries leading to loss of survival. However, the molecular mechanisms underlying olfactory impairment remain poorly understood. In the current study, we exposed juvenile salmon to three environmentally-relevant doses of chlorpyrifos (CPF) and malathion (MAL) individually and to three concentrations of binary mixtures of both compounds. more...

(Submitter supplied) By directly comparing gene expression in wild type, domestic, and GH transgenic strains of salmon, we have found that domestication and GH transgenesis are modifying similar genetic pathways. Genes in many different physiological pathways show modified expression in domestic and GH transgenic strains relative to wild-type, but effects are strongly correlated. Genes specifically involved in growth regulation (IGF-I, GHR, IGF-II, THR) are also concordantly regulated in domestic and transgenic fish, and both strains show elevated levels of circulating IGF-I. more...

(Submitter supplied) This is the first use of cDNA microarrays to study the influence of GH transgenesis on liver gene expression in a non-mammalian vertebrate. Three groups of salmon were examined: transgenic on full ration (T), transgenic on restricted ration (R), and control nontransgenic (C). Daily weight gains in T were approximately 8-fold higher than in C, and 4-fold higher than in R. Differential gene expression in T, R, and C samples was determined using ~ 16,000 gene microarrays. more...
