Marine habitat

Pacific herring are a pelagic fish species found from northern Baja California to northern Honshu Island, Japan. They are found throughout the Puget Sound basin and are a mix of “resident” and “migratory” stocks. 

New research shows that warmer and more acidic oceans could lead to shorter embryos and higher respiration in Pacific herring.

Scientists argue that herring managers should take a tip from stock market investors and diversify the population’s “portfolio.” 

A 2018 paper in the journal Ocean and Coastal Management examines and compares planning approaches used to develop marine protected areas and estuary restoration projects in Puget Sound. It finds that management policies can benefit from increasingly collaborative planning with a focus on multiple benefits such as flood control, salmon recovery, recreation and resilience to climate change. 

During June, near normal air temperatures and continued low precipitation have resulted in highly variable freshwater inputs to Puget Sound. A large Noctiluca bloom extends across the South Central Basin of Puget Sound. Coccolithophores are blooming in Hood Canal. Macroalgae is drifting as mats on the water in Port Madison, South Central Basin, and South Sound. They are also piling up on beaches in South and Central Puget Sound and Whidbey Basin. Juvenile fish are migrating out of the estuaries and meeting a complex thermal habitat. New infrared images tell the story. Meet our ocean acidification expert, Stephen Gonski.

Getting bigger faster can help save juvenile Chinook salmon from a gauntlet of hungry predators ranging from birds and marine mammals to larger fish. We continue our series on the Salish Sea Marine Survival Project with a look at what helps salmon grow and prepare for life in the open ocean.
