Writing Exercise #4

(1) Marlene Lorgen-Ritchie in her post doctoral project entitled “A Temporally Dynamic Gut Microbiome in Atlantic Salmon During Freshwater Recirculating Aquaculture System (RAS) Production and Post-seawater Transfer” (2021) asserts that Atlantic salmon aquaculture are undergoing an expansion of land-based recirculating aquaculture systems (RAS), especially for freshwater (FW) stages of production. (2) Lorgen-Ritchie provides evidence that microbial diversity and richness showed an increase over time across FW production, but declined sharply and significantly 1-week post-SWT before re-establishing itself with a completely different community structure after 4 weeks. (3) The purpose of this dissertation is to describe her graduate work on how juvenile salmon undergo parr-smolt transformation, and become pre-adapted to tolerate seawater (SW) so that a deeper understanding of the interplay between microbial composition and functionality can play a role in optimizing fish performance in tightly regulated RAS production. Lorgen-Ritchie establishes a scholarly relationship with academics both in microbiological and marine biological research as well as other specialties within the biological sciences.
