1. Describe your project, in 4 sentences or less.
I study the growth physiology of red king crab (Paralithodes camtschaticus), specifically comparing wild caught red king crab (from Southeast Alaska) and hatchery-raised red king crab (from the Alutiiq Pride Shellfish Hatchery in Seward, Alaska). There are two aspects to my project: 1. is to determine how often the crabs molt (molt interval) and how much they grow with each molt (growth increment) 2. look at the fluctuations in circulating growth ecdysteroids (20-hydroxyecdysone) in the hemolymph throughout the molt cycle. Additionally, I conduct monthly beach surveys (during the low low monthly tides in Auke Bay) to measure the wild juvenile red king crab that live in the intertidal in order to help determine if there are any differences in growth that may result from rearing crabs in a laboratory over time. By understanding the early life history of king crabs, specifically how they grow and behave during their most vulnerable time (first few years of life), managers will be empowered to manage the fishery in a more informed and predictive manner; moreover, this research may be used to better classify (or “age”) young crabs that are encountered during surveys or other field research opportunities, giving managers and researchers a deeper understanding of how movement and behavior of differing age classes of juvenile king crabs in the field will ultimately affect the fishery into the future. (I know that last sentence is kind of long and a run-on but I only had four sentences!)
