Katherine T. Schmidt (2014)

Katie and a LingcodKatie joined the Fisheries & Conservation Biology Lab in May 2008.  She participated as science crew for the California Collaborative Fisheries Research Program (CCFRP) each summer, serving as field coordinator in 2010 and 2011.

Katie obtained a B.S. from Humboldt State University in 2007.  Before attending Moss Landing Marine Laboratories, she participated in numerous internships and temporary positions, including a summer at Rutgers University Marine Field Station studying burrowing anemones, participating in a wide-spread shore-based survey of gray whales, Stellar sea lions and assisting in acoustic telemetry studies involving harbor seals for three semesters at HSU.  Katie has also conducted surveys for CA Sea Grant Extension Program and Oregon State University – Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO).  Lastly, she held a brief internship at Mote Marine Lab in Florida, quality controlling data for past artificial reef surveys and volunteering at their injured sea turtle rehabilitation hospital.  Generally, Katie is interested in providing the data required to make informed decisions regarding use of fishery resources.

Katie defended her thesis in May 2014.   Her research provided current estimates of life history (growth, age at maturity, length at maturity, and fecundity) for Blue Rockfish, Sebastes mystinus, and Deacon Rockfish, Sebastes diaconus (Frable 2015).  The value differences found between the two species’ traits were slight.  When she compared life history traits from both species combined to historical life history estimates, she found large and significant differences.  The 2010s female fish grow to smaller maximum sizes than they did in the 1980s, 2010s female mature at much smaller sizes than they did in the 1960s, and 2010s female fish mature 1-2 years earlier than they did in the 1980s.  However, the total fecundity of females in relation to their length remained the same between 1960s and 2010s fish.  (Please note the current life history trait values were estimated from a combination of Blue and Deacon Rockfish samples since the past estimates from the 1960s and 1980s treated them as one species, and there is no way to separate this information currently).   The observed shift in the life history values is probably the population’s response to the overfishing of these species that occurred in the 1980s to the early 1990s.  These new life history values will be used in the next Blue Rockfish/ Deacon Rockfish stock assessment.

Katie is currently volunteering at the NMFS Southwest Fisheries Science Center with Dr. Munch’s research group, which focuses on trans-generational plasticity of life history traits in Sheepshead Minnow.  She is also assisting with a historical catch reconstruction of Rockfishes in Puget Sound, WA.  By mid-2016, she will be starting a position with NOAA Fisheries West Coast Region in the Central Valley office in Sacramento.
