Nope. They were using a Ricker model, modified for the two-year life
cycle of the pink salmon, which has a density dependent growth term in
it. They estimated rates of increase from an extensive data set, then
added a parasite induced mortality term estimated from years that salmon
populations were exposed to sea lice. The time to 99% extinction was
estimated from the population growth rates, and is about 4 years.

Just a question, because I don´t know anything about pink salmon. Do
all the pink salmon of a particular year return at the same time?

Just wondering because of the two year cycle you mentioned.
