Iteroparous Capable of spawning more than once before death
Jacks Male salmon that return from the ocean to spawn one or more years before
full-sized adults return. For coho salmon in California, Oregon,
Washington, and southern British Columbia, jacks are 2 years old, having
spent only 6 months in the ocean, in contrast to adults, which are 3 years
old after spending 1 ½ years in the ocean.
Jills Female salmon that return from the ocean to spawn one or more years
before full-sized adult returns. For sockeye salmon in Oregon,
Washington, and southern British Columbia, jills are 3 years old (age 1.1),
having spent only one winter in the ocean in contrast to more typical
sockeye salmon that are age 1.2, 1.32.2, or 2.3 on return.
Kokanee The self-perpetuating, non-anadromous form of O. nerka that occurs in
balanced sex ration populations and whose parents, for several generations
back, have spent their whole lives in freshwater.
Lambda Also known as Population growth rate, or the rate at which the abundance
of fish in a population increases or decreases.
LRL Laboratory Reporting Level (USGS NAWQA data)- Generally equal to
twice the yearly determined LT-MDL. The LRL controls false negative
error. The probability of falsely reporting a non-detection for a sample that
contained an analyte at a concentration equal to or greater that the LRL is
predicted to be less than or equal to 1 percent.
Major Population A group of salmonid populations that are geographically and
Group (MPG) genetically cohesive. The MPG is a level of organization between
demographically independent populations and the ESU.
