A set of 96 genetic markers, or single nucleotide polymorphisms (SNPs), winnowed by Columbia River basin researchers from a list of 4,439 previously identified in Pacific lamprey could help give researchers insights into the lives and life influences faced by the diminished, but highly valued, fish species, according to a research paper made available last week online.

Pacific lamprey migrating up the Columbia River will find their route past McNary Lock and Dam a bit easier to travel, thanks to a prototype lamprey-passage structure installed in the downstream end of the Oregon shore fish ladder, U.S. Army Corps of Engineers officials announced this week.
