RNA-Seq Analysis of the Growth Hormone Transgenic Female Triploid Atlantic Salmon () Hepatic Transcriptome Reveals Broad Temperature-Mediated Effects on Metabolism and Other Biological Processes.

This study examined the impact of rearing temperature (10.5, 13.5 or 16.

Interacting Effects of Sea Louse () Infection and Formalin-Killed on Atlantic Salmon Skin Transcriptome.

(sea lice) and bacterial co-infection threatens wild and farmed Atlantic salmon performance and welfare. In the present study, pre-adult -infected and non-infected salmon were intraperitoneally injected with either formalin-killed bacterin (ASAL) or phosphate-buffered saline (PBS). Dorsal skin samples from each injection/infection group (PBS/no lice, PBS/lice, ASAL/no lice, and ASAL/lice) were collected at 24 h post-injection and used for transcriptome profiling using a 44K salmonid microarray platform.

Comparative Genomics Analysis of Isolated from Lumpfish () in Newfoundland Reveal Novel Chromosomal Organizations.

is a Gram-negative marine pathogen causative agent of vibriosis in a wide range of hosts, including invertebrates and teleosts. Lumpfish (), a native fish of the North Atlantic Ocean, is utilized as cleaner fish to control sea lice () infestations in the Atlantic salmon () aquaculture industry. is one of the most frequent bacterial pathogens affecting lumpfish.

Transcriptomic Profiling in Fins of Atlantic Salmon Parasitized with Sea Lice: Evidence for an Early Imbalance Between Chalimus-Induced Immunomodulation and the Host's Defense Response.

Parasitic sea lice (e.g., ) cause costly outbreaks in salmon farming.

Impact of rearing temperature on the innate antiviral immune response of growth hormone transgenic female triploid Atlantic salmon (Salmo salar).

AquAdvantage Salmon (growth hormone transgenic female triploid Atlantic salmon) are a faster-growing alternative to conventional farmed diploid Atlantic salmon. To investigate optimal rearing conditions for their commercial production, a laboratory study was conducted in a freshwater recirculating aquaculture system (RAS) to examine the effect of rearing temperature (10.5 °C, 13.

Optimization and field use of a bioassay to monitor sea lice Lepeophtheirus salmonis sensitivity to emamectin benzoate.

A bioassay for sea lice Lepeophtheirus salmonis sensitivity towards emamectin benzoate (EMB) was validated for field use. A probit regression model with natural responsiveness was used for the number of affected (moribund or dead) sea lice in bioassays involving different concentrations of EMB. Bioassay optimization included an evaluation of the inter-rater reliability of sea lice responsiveness to EMB and an evaluation of gender-related differences in susceptibility.
