Neala Kendall (Research Scientist, Statewide Quantitative Synthesis and Reporting Unit, Fish Program, Washington Department of Fish and Wildlife) will be presenting Monday (3/4/19) from 3-4 pm in the Physics and Astronomy Tower, Room C520.
Title: Density-dependent factors shaping salmon and steelhead survival and life history
In Washington State and beyond, we want higher numbers of salmon and steelhead for conservation and recreation. Salmon and steelhead have been highly impacted by a multitude of factors over the last century, and recovering them has been challenging. Density dependence is an important factor that can influence survival and life history of salmon and steelhead and should be considered when taking management actions. In this talk, I will discuss two recent projects where considering density dependence was helpful. First, I’ll discuss factors, including intraspecific density dependence, related to the life history strategies anadromy and residency in steelhead and rainbow trout (Oncorhynchus mykiss) across their Pacific Rim range. Second I’ll talk about an ongoing project asking the question: in the past, when more hatchery Chinook salmon (O. tshawytscha) have been released into the Salish Sea, has there been an associated increase in the number of hatchery Chinook salmon that have survived their migration in the ocean and returned as adults. We consider the abundance of both juvenile Chinook and pink salmon (O. gorbuscha) as density dependence has appeared to play a role in shaping survival rates.
