In the study reported here on estimating survival rates of Atlantic salmon smolts from four rivers over 14 years, factors that could be standardized include the tag type, the size distribution of smolts being tagged, the tag implantation procedures and the placement of the receiver arrays. By standardizing these elements of the study, the individual river experiments are more likely to be exchangeable and by using hierarchical models, the inferences on the parameters of interest less uncertain.

The authors acknowledge the field work contributions over the years of study of staff from the Atlantic Salmon Federation, in particular Graham Chafe, who were involved in the tagging operations, receiver deployments, and data retrievals. This study would not have been possible without the financial contributions of a large number of individuals, foundations, and organizations that sponsored this research through donations to the Atlantic Salmon Federation. A complete list of contributors can be found at www. We also acknowledge the editorial contributions of the two anonymous reviewers.

Abstract The migration dynamics and inter-annual variation in early at-sea survival of Atlantic salmon Salmo salar smolts over 14 years of study are reported for four river populations located in the Gulf of St. Figure 1. Open in new tab Download slide. Figure 2. Figure 3. The state process survival is represented by a binary variable z i , j , which takes the value 1 if individual i is alive at the detection point j and 0 otherwise.
Preliminary analyses of the proportions of tags detected at the arrays suggested a positive association with the fork length of the fish at tagging Figure 4.leapsrabacksute.tk

There is also a decreasing temporal trend linear regression of median length vs. Survival probabilities relative to the length of fish at tagging by river and tag type overall are modelled as linear effects on the logit scale with tag type included as an interaction term with fork length i.
