Tagging studies, using technologies such as satellite telemetry, collect information on both bycatch and target species to identify and characterize their habitat** [1]. These habitat data can be used with fisheries data, such as effort and bycatch interaction rates, [1] to identify habitat or interaction 'hotspots' and inform management. Bycatch management is becoming increasingly dynamic, aided by advances in tagging telemetry. For example, a recent study identified the principal environmental variables influencing the co-occurrence between whale sharks, baleen whales and tuna purse-seine fisheries [2]. These mega-fauna were mostly observed in productive areas during particular seasons.
See 'Spatial and Temporal Measures' for more information.
**Studies examining post-release mortality of bycatch species utilise tagging. Use the filter ‘post-release mortality’ to discover these references.
