What is fallback ?: metrics needed to assess telemetry tag effects on Anadromous Fish behavior
Hydrobiologia, 2009Co-Authors: Holly J. Frank, Martha E. Mather, Joseph M. Smith, Robert M. Muth, John T. Finn, Stephen D. MccormickAbstract:Telemetry has allowed researchers to document the upstream migrations of Anadromous Fish in freshwater. In many Anadromous alosine telemetry studies, researchers use downstream movements (“fallback”) as a behavioral field bioassay for adverse tag effects. However, these downstream movements have not been uniformly reported or interpreted. We quantified movement trajectories of radio-tagged Anadromous alewives (Alosa pseudoharengus) in the Ipswich River, Massachusetts (USA) and tested blood chemistry of tagged and untagged Fish held 24 h. A diverse repertoire of movements was observed, which could be quantified using (a) direction of initial movements, (b) timing, and (c) characteristics of bouts of coupled upstream and downstream movements (e.g., direction, distance, duration, and speed). Because downstream movements of individual Fish were almost always made in combination with upstream movements, these should be examined together. Several of the movement patterns described here could fall under the traditional definition of “fallback” but were not necessarily aberrant. Because superficially similar movements could have quite different interpretations, post-tagging trajectories need more precise definitions. The set of metrics we propose here will help quantify tag effects in the field, and provide the basis for a conceptual framework that helps define the complicated behaviors seen in telemetry studies on alewives and other Fish in the field.

80’s population-specific compositions of two related Anadromous shad species during the oceanic phase determined by microchemistry of archived otoliths
Canadian Journal of Fisheries and Aquatic Sciences, 2019Co-Authors: David José Nachón, Gilles Bareille, Hilaire Drouineau, Hélène Tabouret, Catherine Taverny, Catherine Boisneau, Sylvain Bérail, Christophe Pécheyran, Fanny Claverie, Françoise DaveratAbstract:The specific stock composition and dispersion of Anadromous Fish species aggregations in the marine environment are poorly known, while they can play a major role in the metapopulation dynamics. Otolith microchemistry has proven to be a powerful tool to address natal origins of Anadromous Fish. We used archived otolith microchemistry to investigate the population-specific composition of European shads (Alosa alosa and Alosa fallax) subadults in the ocean during the 80’s. The allocation of natal origin was addressed relying on contemporary water and juveniles signatures within a Bayesian model. A great discrimination of natal origin was obtained at the Biscay Gulf scale. However, the discrimination of 80’s natal origin for the southern rivers with similar geology based on 2013 water and juveniles baselines was doubtful. Our results showed that the most abundant southern populations were dominant, suggesting that population-specific composition was related to population relative abundance. The dispersion in the marine environment was plastic; alternatively shads were found large distances away from their natal rivers, while others remained in the vicinity of their natal river plume.
