Effect of temperature on Atlantic salmon gut microbiota (2019)

Atlantic salmon smolt were placed in tanks at 15 C and fed for 4 weeks before the tank temperature was increased to 19 C. Feeding continued for up to four months by which time feeding rates had significantly declined. The fish then experienced a recovery period at 15 C for 4 weeks. Multiple tanks were used stocked with 200-300 fish. Distal gut digesta was stripped at the end of the three temperature phases (initial, thermal stress, recovery). Microbiota in samples was assessed using 16S rRNA gene (V1-V3 region) amplicon sequencing using the MiSeq Illumina platform. The dataset provided here is the first of three and was performed in 2018.
