Fish in all the world's oceans exhibit variable body size and growth over time, with some populations exhibiting long-term declines size. These patterns can be caused by a range of biotic, abiotic, anthropogenic factors impact productivity harvested populations. Within given species, individuals often life history strategies that may cause groups to buffered against change. One most studied size-at-age has been salmon; Chinook salmon Northeast Pacific Ocean are largest-bodied species have experienced Using monitoring data, we develop novel models link observed changes traits environmental variability. Our results identify three distinct trends across 48 stocks our study. Differences among correlated ocean distribution, migration timing, freshwater residence. We provide evidence driven interannual variation certain oceanographic processes competition pink salmon.
