  text: Brown trout (Salmo trutta) is an important aquaculture species in Germany,
    but its production faces challenges due to global warming and a high embryo mortality.
    Climate factors might influence the fish’s bacterial community (BC) and thus increase
    embryo mortality. Yet, knowledge of the physiological BC during ontogeny in general
    is scarce. In this project, the BC of brown trout has been investigated in a period
    from unfertilized egg to 95 days post fertilization (dpf) using 16S rRNA gene
    amplicon sequencing. Developmental changes differed between early and late ontogeny
    and major differences in BC occurred especially during early developmental stages.
    Thus, analysis was conducted separately for 0 to 67 dpf and from 67 to 95 dpf.
    All analyzed stages were sampled in toto to avoid bias due to different sampling
    methods in different developmental stages. The most abundant phylum in the BC
    of all developmental stages was Pseudomonadota, while only two families (Comamonadaceae
    and Moraxellaceae) occurred in all developmental stages. The early developmental
    stages until 67 dpf displayed greater shifts in their BC regarding bacterial richness,
    microbial diversity, and taxonomic composition. Thereafter, in the fry stages,
    the BC seemed to stabilize and changes were moderate. In future studies, a reduction
    in the sampling time frames during early development, an increase in sampling
    numbers, and an attempt for biological reproduction in order to characterize the
    causes of these variations is recommended.
