Conservation Status
Habitat loss or degradation of nearshore intertidal zones that serve as a refuge for juvenile pollock are a current concern, and there is a call for more research related to this topic (Cargnelli et al. 1999). There is some speculation that these habitats may be a bottleneck restricting population size. There are additional concerns regarding the effect of overfishing on pollock population sizes. After catch rates increased steadily throughout the 1970s and early 1980s, catch rates dropped 82% between 1986 and 1996 (Mayo 1998). This was accompanied by a 36% decrease in spawning stock biomass between 1986 and 1994. There is speculation that overfishing may be causing important changes in population structure as well, for example the decrease in mean age at maturity and mean size at maturity observed by Caragnelli et al. (1999).
