Abstract
- Telemetry has major potential for application to fish habitat science and management, but to date it is underutilized in this regard. We posit this is because (1) fish telemetry projects are often geared towards detecting fish movement, opposed to systematically sampling habitat selection, and (2) there are often differences in scale between telemetry data and management decisions. We discuss various ways in which telemetry can contribute to fish habitat science and present some considerations for improving its application to this field. To date, most fish telemetry studies have been descriptive (e.g., fish use area A more than area B); greater adoption of more inferential study approaches that assess causal ecological drivers of movement and space use would be of value and require more extensive measurement of environmental conditions. We conclude by presenting a conceptual framework for scaling from individual studies to broad applications in habitat management. Established telemetry networks can readily support synthesis activities, although fish tracking data and environmental data are rarely stored together, and current disconnects among repositories may constrain broad integration and scalability. Si le potentiel d'application de la telemetrie a l'etude et a la gestion des habitats du poisson est important, l'approche demeure sous-utilisee a ce jour. Nous postulons que les causes en sont (1) le fait que les projets de telemetrie appliquee au poisson sont souvent axes sur la detection des deplacements des poissons, par opposition a l'echantillonnage systematique de la selection d'habitats et (2) les differences d'echelles frequentes entre les donnees de telemetrie et les decisions de gestion. Nous abordons differentes approches par lesquelles la telemetrie peut contribuer a l'etude de l'habitat du poisson et certaines considerations permettant d'en ameliorer l'application a ce domaine d'etude. La plupart des etudes telemetriques sur les poissons a ce jour sont descriptives (p. ex. les poissons utilisent plus la region A que la region B). Une adoption plus large d'approches plus inferentielles qui evaluent les facteurs ecologiques causals des deplacements et de l'utilisation de l'espace serait utile et necessiterait des mesures plus vastes des conditions environnementales. Nous concluons en presentant un cadre conceptuel pour passer de l'echelle d'etudes individuelles a celle d'applications plus larges en gestion des habitats. Des reseaux telemetriques etablis peuvent aisement appuyer des activites de synthese, mais les donnees de suivi des poissons et les donnees environnementales sont rarement conservees ensemble et le manque d'harmonisation des depots de donnees peut limiter l'integration et l'extensibilite de ces dernieres.
