Life History of Pacific Northwest Fishes through Age and Growth Structures Active
Otolith, Scale, Fin Ray
Used as tools to provide life history information such as: age, growth, orgin, size at age data, migration history, etc.
The focus of our research is the ecological analysis of Pacific Northwest fishes through age and growth structures such as: scales, fin rays and otoliths (small calcium carbonate deposits beneath the brain used in hearing and balance that grow in proportion to the overall growth of the fish). These structures are utilized as research tools for understanding life histories and habitat importance related to both species and habitat preservation as well as restoration. Various research techniques are continually being applied, either alone or in combination, to answer questions of concern. The techniques include, but are not limited to: aging from otoliths, analyzing otolith microstructure patterns for growth, residence and thermal marks, identifying migration patterns, maternal signals and stock of origin from otolith microchemistry (through incorporation of elements from surrounding habitat), aging and growth from scales, and utilizing fin rays as a non-lethal substitute for otoliths.
Puget Sound Fall Chinook Estuarine Utilization
Puget Sound Chinook salmon are just one of many species whose populations have declined to precariously low levels (ESA threatened status) coinciding with widespread loss of estuarine and nearshore habitats throughout Puget Sound. Juvenile fall Chinook salmon utilize several habitats during their migration to the open ocean. One important habitat is the estuary, particularly tidal deltas, which provide a migratory corridor, protection from predators, and opportunity to forage, grow and adapt to seawater. In response to the loss of vital habitat, monitoring and restoration efforts within the tidal delta and nearshore habitats of large river deltas are becoming common throughout Puget Sound. A baseline of information that includes characterization of life history types, estuary residence times, growth rates, and habitat use is needed for evaluating the potential response of natural and hatchery origin Fall Chinook salmon to restoration efforts, therefore helping to evaluate restoration success and guide complementary monitoring efforts.
The Western Fisheries Research Center (WFRC) and its partners are using otoliths to examine the life history of Fall Chinook salmon within several large river deltas of Puget Sound (Skagit, Snohomish, Nisqually rivers). Chinook residence times and growth rates in various habitats, and the overall importance of estuarine utilization to juveniles as well as the returning adult population are the focus of the research.

Non-Native West Coast American Shad Life History
American shad, an anadromous species native to the East Coast of the United States, was transported to California in 1871. Over the years, they have expanded their range south to Mexico and north to Alaska. Since American shad have become well-established and numerous in many systems, it is important to understand their potential impacts and interactions with threatened fish species, such as salmon. Understanding these interactions may become more important as environmental conditions change. There have been a few shad investigations in their introduced range but much of our knowledge of shad biology and ecology is from East Coast populations. Baseline life history information is crucial to understanding the extent to which this non-native species can impact native fishes.
The WFRC and its partners are using otoliths and scales as tools to increase our knowledge of shad life history throughout its entire West Coast range. Most recently, the research is focused on the use of otolith microchemistry to help explain habitat usage and migration (i.e., Do some shad, as juveniles, move back and forth between fresh and estuarine or marine waters? Do some shad exhibit extended freshwater rearing in their first year?), and more accurately describe life history characteristics of the adult population as a whole. This would include microchemical patterns from otoliths to corroborate repeat spawning patterns initially identified through scale analysis.

Validation of a Non-Lethal Approach to Life History Examination
Many freshwater and anadromous fish species, including bull trout, display diverse life history patterns, are highly migratory, and use multiple habitats throughout their life history. Connectivity among these different habitats is critical for providing access to spawning, rearing, foraging, overwintering, and migratory habitats. However, to protect connectivity, we must first know what habitats are used and when they are used. Migratory and life history patterns of salmonids, including bull trout and other listed fishes, is predominately evaluated using tagging techniques. Unfortunately, these methods only provide information for specific life stages, are not practical for young fish, suffer from low recapture rates, are temporally limited due to tagging constraints and are expensive for fish like bull trout with large-scale migratory behaviors or that use diverse habitats.
Fortunately, life history information can be obtained through alternative means. Examination of fish otoliths, both visually and chemically, can be used for obtaining life history information about fish including age, growth and habitat usage. Specifically, microchemical analysis of otoliths can provide information on migratory behavior, individual life history patterns, maternal life history patterns, and large-scale habitat use in basins with significant variation in water chemistry. Microchemistry studies have typically relied on analysis of otoliths from incidental mortalities or lethal sampling, but there is interest in moving toward non-lethal methods, especially for threatened and endangered species such as bull trout. Fin rays can potentially be used as an alternative to otoliths for answering the same questions but in a non-lethal way. Some initial microchemistry research obtained similar results between otoliths and rays. However, questions remain as to the extent to which microchemical analysis of non-lethally removed fin rays can be used to obtain the same information normally obtained through lethal sampling of otoliths.
Using rainbow trout and steelhead as proxies for the endangered bull trout, WFRC and its partners are examining otoliths and rays to provide a clearer understanding of how fin rays develop relative to otoliths, and to determine the utility of rays regarding the existence of chemical signals associated with maternal effects.
