Using modern biochemical techniques, three long-term physiological, genetic, and isotopic datasets will be generated using immunohistochemistry, DNA-sequencing, and stable isotope analysis. This project will perform analysis on previously collected larval cowcod (Sebastes levis) and bocaccio (Sebastes paucispinis), two commercially important species that have experienced dramatic decline throughout the 20th century. This work will contribute to understanding the 'winners' and 'losers' in future ocean conditions, and provide fishery managers with crucial information that may be applied to maintain commercially-important fishery stocks and preserve local biodiversity. These specimens together with a corresponding oceanographic dataset were collected by the California Cooperative Oceanic Fisheries Investigations program and represent the longest fishery-independent dataset in the world. To better understand factors that affect larval physiology and predator-prey interactions, this project will apply modern biochemical techniques to larval fish collections spanning 67 years. The primary factors affecting early-life mortality are predation and starvation, which are affected by oxygen, nutrients, and other ocean conditions including warming and acidification linked to human activity that has increased carbon emissions. Determining how environmental factors influence larval fish populations is essential to predicting the adult population structure and will enhance fishery management strategies. The fellowship supports research and training of the fellow that will utilize biological collections in innovative ways.
