Spatial and temporal variation in rosy rockfish (Sebastes rosaceus) life history traits

Ryan completed his undergraduate studies at Westmont College in 2010 with a B.S. in Chemistry and a minor in Biology. Before graduation, he worked as a research assistant at the Kodiak Seafood and Marine Science Center, where he participated in several biochemical research projects aimed at creating new food products and reducing fishery-related waste.

Ryan grew up participating in the commercial salmon fishery with his family on Kodiak Island. Both throughout his undergraduate career and after graduation, Ryan continued to work as a full-time crewman fishing for salmon in Bristol Bay and the Gulf of Alaska.

During the fall of 2010, Ryan returned to Kodiak and was hired as a Biological Technician II for the Alaska Fisheries Science Center (NMFS). Here, he was responsible for maintaining water quality for ongoing experiments and assisting with studies involving juvenile king and tanner crab. One such project evaluated the potential effects of ocean acidification on these species. Another important, ongoing project looked into the economic and ecological viability of reestablishing a healthy red king crab population around Kodiak Island.

Ryan joined the Fisheries and Conservation Lab  at MLML in the fall of 2012.  Ryan’s thesis project investigated spatial and temporal variation in the demography and life-history characteristics of Rosy Rockfish (Sebastes rosaceus).  By ageing Rosy Rockfish otoliths collected by NMFS in the 1980s as well as those collected from 2012 to 2014, Ryan sought to answer questions about variability in growth parameters over the past four decades. In addition, collections of Rosy Rockfish south of Point Conception were used to investigate spatial differences between southern and central California Rosy Rockfish populations.

Since beginning his studies at MLML, Ryan has served as science crew and volunteer coordinator for the California Collaborative Fisheries Research Program (CCFRP). Ryan  helped to lead field work for the Rockfish Conservation Area Project between 2012-2014-- a short-term project to evaluate the performance of Rockfish Conservation Areas (RCAs) after 10 years of implementation.

Ryan defended his thesis in the spring of 2016, and was hired as a technician for the Fisheries and Conservation Biology Lab where he continues to participate in lab projects that include CCFRP and the development of new video lander tools to improve fisheries management of Pacific rocky reefs.
