Coastal seine surveys contain some of the only direct measures of age-0 abundance for Atlantic cod (Gadus morhua) and Pacific cod (Gadus macrocephalus), yet their utility in forecasting future year-class strength has not been evaluated among regions. We analyzed coastal time series from the Gulf of Alaska, Newfoundland, and Norway to test the hypothesis that recruitment signals are stronger when assessed under thermal conditions that provide high juvenile growth potential. Weaker recruitment signals were associated with low growth potential from cold winters (Newfoundland) and recent warmer summers (Norway). We conclude that temperature-dependent growth strongly influences the utility of coastal surveys in recruitment forecasting among regions. Temporal changes in growth potential (e.g., via climate change) will likely affect recruitment signals by way of changes in juvenile mortality or spatial shifts to more favorable thermal habitats.

Purpose – The purpose of this paper is to build on previous studies on the link between objective and subjective person-organization fit (P-O fit) and argue that the strength between objective and subjective fit is contingent on advertisement attractiveness and organizational image. Accordingly, the authors observe if advertisement attractiveness and organizational image help to strengthen the objective-subjective P-O fit relation. Design/methodology/approach – The authors conduct a survey among 942 individuals and compare between prospective jobseeker (n=629) and actual jobseeker (n=313) subsamples. Findings – Generally, the authors show that ad advertisements positively moderates the relation between objective and subjective fit. Moreover, the authors show that advertisement attractiveness moderates the relationship between objective and subjective fit for prospective jobseekers while the moderating influence of advertisement attractiveness is not significant for actual jobseekers. Organizational image, however, is shown to act as a negative moderator, particularly for the actual jobseeker sample. Research limitations/implications – The authors aim to contribute to prior research by emphasizing how the link between objective and subjective P-O fit can be elevated by cues such as advertisement attractiveness and might be disturbed by a very good organizational image. Practical implications – This study informs practitioners how two important recruitment signals, job advertisement and organizational image, influence the transmission of objective into subjective fit and thus help firms to improve their recruitment efforts. Originality/value – Even though many studies support the effects of P-O fit on organizational attractiveness or application intentions, only little is known in terms of how the relationship between the two dimensions of P-O fit – objective and subjective fit – can be positively influenced. Hence, there is a lack of understanding of how firms can focus their recruitment efforts effectively on highly fitting individuals.

Abstract Age-0 juveniles may be the earliest, reliable indicators of recruitment into commercial marine fisheries, but independent fisheries assessments are usually conducted on older life stages in adult habitats. We used an 8 year juvenile gadid survey along the coast of Kodiak, Alaska to examine annual abundance, growth and mortality in age-0 Pacific cod (Gadus macrocephalus), with comparisons to saffron cod (Eleginus gracilis) and walleye pollock (Gadus chalcogrammus) where possible. Annual abundance of age-0 fish was positively correlated among all three species, suggesting Pacific gadids respond similarly to processes controlling pre-settlement survival and/or delivery to coastal nurseries. In Pacific cod, June temperature was positively correlated with size-at-settlement but post-settlement growth was density- rather than temperature-dependent. Age-0 abundance indices for Pacific and saffron cod predicted the number of age-1 fish the following year (i.e. positive “recruitment signals”), but only in the larger nursery (Anton Larsen Bay) where age-1 gadids were more likely to remain resident after their first year. Recruitment signals for Pacific cod improved with later estimates of age-0 abundance, likely because of high mortality following settlement in July. In contrast, very few age-0 and age-1 walleye pollock were caught across the entire time-series of the survey. Collectively, these data suggest that nearshore surveys may be a tractable means of examining early life history processes and assessing year-class strength in juvenile Pacific and saffron cod, but have relatively low value in understanding the population dynamics of walleye pollock.
