Jacob (Jake) Gregg

Jake Gregg manages the research aquaculture system at the Marrowstone Marine Field Station which produces Specific Pathogen Free (SPF) marine fish. The availability of SPF fish over the past 21 years has led to new discoveries in disease ecology that are documented in dozens of peer reviewed publications.

Jake’s broad interests in physiology and ecology began during his undergraduate studies in human performance, and continued through graduate school, where he studied the early life history of lingcod, a top predatory fish of the western North Pacific Ocean. During his lingcod research, Jake adapted aquaculture techniques to a novel species. This experience led to his recruitment by the USGS, where he was asked to develop a research hatchery for Pacific herring, an important forage fish species. Over the past 21 years the hatchery at the USGS Marrowstone Marine Field Station has developed into mainstay of the research projects that occur at the center. Marrowstone regularly produces 20,000 post-metamorphosed herring for disease research. The hatchery has also raised other marine species to meet research needs. In addition to marine disease research, Jake has contributed to research in phylogenetics, age-and-growth, parasitology, contaminates, tagging, and habitat restoration. Jake has also been involved in K-12 educational outreach throughout his career. The most notable example, a collaboration between the USGS, the US Navy and local schools that documented fish assembly changes at a local restoration site using 8th grade students as the primary data collectors.
