Variability in body growth is an important part of variability in fish populations
It has long been established, indeed it is almost axiomatic, that annual variability in births of new fish (“recruitment”) is the most important reason why the total mass of fish populations varies from year to year. The rate of which individual fish grow (“body growth”) is also known to vary from year to year, but is generally considered to be fairly unimportant in explaining population variability.
Read moreA new guide on how to figure out which parts of DNA are actually expressed
Scientists trained in ecology and physiology are increasingly able to complement their work with the burgeoning field of “functional genomics”, i.e. the study of which parts of DNA (the “genome”) are actually expressed and used to make proteins under different conditions. A new guide is now provided for those from non-genetic fields to harness the power of fast computers and rapid technology in sequencing the letters in DNA, so that they can infer how animals respond to the environment.
Read moreThe blue-backed basslet, a new species from the Honduras
Reef fish species from waters deeper than 130 m are difficult to collect manually, because they are too deep for SCUBA divers. But now manned submersibles equipped with underwater vacuums are able to suck up new specimens with surprising alacrity. Among the specimens slurped up by one such submersible is brand new blue and gold species of basslet: the blue-backed basslet (Lipogramma adabeli), with distinct blue coloration, genetics, and habitat use distinguishing it from other similar species.
Read moreDesigning salmon-friendly dam turbines
The Columbia River used to host returns of nearly 9 million salmon every year, led by the largest returns in the world of Chinook salmon (4.4 million fish). But construction of multiple large dams on various tributaries and the Columbia River itself, eliminated salmon from vast tracts of rivers above impassable dams, and also had a serious effect on salmon survival in the remaining areas.

After graduating from WSU and enrolling at UW, my first task as a graduate student was to assist Ken Chew in setting up several oyster and mussel field stations to investigate shellfish diseases. I did find getting paid to conduct research while taking numerous interesting classes really stimulated my interest in graduate school. Ken introduced me to the questionable pleasure of consuming Olympic oysters fresh in the field. Although I love most shellfish, I never developed a fondness for raw oysters, although they are not too bad when consumed with a good Scotch.

I’m from a small island off the coast of Maine and was never in doubt that I would work in fisheries in some way during my career. However, I did not have a well-organized plan, and my path to the University of Washington began by following my wife to Washington state after our graduation from Dartmouth College. I spent several years working a variety of “odd jobs,” from trapping flying squirrels to electrofishing the small streams of the Olympic Peninsula before realizing I needed to pursue graduate school.

At the age of five, I was bitten with marine biology when a crab pinched my toe. Ever since, I have sought justice by eating as many crabs as possible.

My association with the School of Aquatic and Fishery Sciences and its predecessor, the College of Fisheries, has been 56 years in the making and has been at the center of just about every one of my major life-making decisions; I will be forever indebted to SAFS and its faculty, past and present.

I grew up fishing in the Rocky Mountains of Canada and off the coast of central California. It was when I was a dockworker and unloading fishing boats in Port San Luis, California that I realized I wanted to become more involved with the assessment and management of fisheries.

SAFS is not just about academic training, but also about working with fishers, managers, policy-makers and industry to truly understand how fisheries science works in the real world. I will be forever grateful for that opportunity.
